102-748: KeePass comes in two different variants: KeePass 1.x and KeePass 2.x. Although the 1.x variant is the former variant it is supported indefinitely: Dominik Reichl: "2.x isn't the successor of 1.x, and 1.x isn't dead". KeePass 2.x has a different software basis in C# instead of the former C++ . Mainly communication features are extended in KeePass 2.x: authentication with the Windows user account , remote and shared database editing as well as many plugins allowing communication and authentication with different web browsers , databases and more. KeePass 1.x and 2.x support

204-476: A File Transfer Protocol (FTP) client for browsing file servers, the ability to block images from individual domains (until version 72), a 3D page inspector (versions 11 to 46), tab grouping (until version 44), and the ability to add customized extra toolbars (until version 28). Functions can be added through add-ons created by third-party developers . Add-ons are primarily coded using an HTML , CSS , JavaScript , with API known as WebExtensions , which

306-546: A Metro-style version of Firefox, optimized for touchscreen use, on the "Aurora" release channel. However, on March 14, 2014, Mozilla cancelled the project because of a lack of user adoption. In March 2017, Firefox 52 ESR, the last version of the browser for Windows XP and Windows Vista , was released. Support for Firefox 52 ESR ended in June 2018. Traditionally, installing the Windows version of Firefox entails visiting

408-526: A blacklist and whitelist of sites that will be used in the filter. Version 23, released in August 2013, followed the lead of its competitors by blocking iframe , stylesheet, and script resources served from non-HTTPS servers embedded on HTTPS pages by default. Additionally, JavaScript could also no longer be disabled through Firefox's preferences, and JavaScript was automatically re-enabled for users who upgraded to 23 or higher with it disabled. The change

510-467: A cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are free, open-source, and cross-platform. Mono also joined Microsoft but was not merged into .NET. As of November 2024, the most recent stable version of

612-422: A semitone higher in pitch . This is similar to the language name of C++ , where "++" indicates that a variable should be incremented by 1 after being evaluated. The sharp symbol also resembles a ligature of four "+" symbols (in a two-by-two grid), further implying that the language is an increment of C++. Due to technical limits of display (standard fonts, browsers, etc.), and most keyboard layouts lacking

714-420: A backing field, or implement arbitrary getter and setter functions. A property is read-only if there's no setter. Like with fields, there can be class and instance properties. The underlying methods can be virtual or abstract like any other method. Since C# 3.0 the syntactic sugar of auto-implemented properties is available, where the accessor (getter) and mutator (setter) encapsulate operations on

816-419: A class can implement any number of " interfaces " (fully abstract classes). This was a design decision by the language's lead architect to avoid complications and to simplify architectural requirements throughout CLI. When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order (i.e. the same signature ), similar to Java , C# allows both

918-425: A configuration menu at about:config for power users , and location-aware browsing (also known as " geolocation ") based on a Google service. Firefox has an integrated search system which uses Google by default in most markets. DNS over HTTPS is another feature whose default behaviour is determined geographically. Firefox provides an environment for web developers in which they can use built-in tools, such as

1020-475: A database, parsing an XML file, or searching through a data structure, shifting the emphasis onto the actual program logic to help improve readability and maintainability. C# used to have a mascot called Andy (named after Anders Hejlsberg ). It was retired on January 29, 2004. C# was originally submitted to the ISO/IEC JTC 1 subcommittee SC 22 for review, under ISO/IEC 23270:2003, was withdrawn and

1122-603: A function (i.e. hiding the former implementation). To do the latter, you have to specify the new keyword. Extension methods in C# allow programmers to use static methods as if they were methods from a class's method table, allowing programmers to virtually add instance methods to a class that they feel should exist on that kind of objects (and instances of the respective derived classes). The type dynamic allows for run-time method binding, allowing for JavaScript-like method calls and run-time object composition . C# has support for strongly-typed function pointers via

1224-611: A new project called Servo to write a completely new and experimental browser engine utilizing memory safe techniques written in Rust . In 2018, Mozilla opted to integrate parts of the Servo project into the Gecko engine in a project codenamed the Quantum project. The project completely overhauled Firefox's page rendering code resulting in performance and stability gains while also improving

1326-427: A nickname of the red panda , which became the mascot for the newly named project. For the abbreviation of Firefox, Mozilla prefers Fx or fx, although it is often abbreviated as FF . The Firefox project went through many versions before version 1.0 and had already gained a great deal of acclaim from numerous media outlets, such as Forbes and The Wall Street Journal . Among Firefox's popular features were

1428-435: A number of plugins , although 2.x allows more plugins. It has a password generator and synchronization function, supports two-factor authentication , and has a Secure Desktop mode. It can use a two-channel auto-type obfuscation feature to offer additional protection against keyloggers . KeePass can import from over 30 other most commonly used password managers. A 2017 Consumer Reports article described KeePass as one of

1530-400: A plugin architecture. There are various plugins available from the KeePass website (such as import/export from/to various other formats, database backup, integration, automation, etc.). Note that plugins may compromise the security of KeePass, because they are written by independent authors and have full access to the KeePass database. KeePass has an opensource wrapper, QuicKeepass, that allows

1632-465: A plugin. The CSV output is compatible with many other password safes like the commercial closed-source Password Keeper and the closed-source Password Agent. Also, the CSVs can be imported by spreadsheet applications like Microsoft Excel or OpenOffice / LibreOffice Calc . File format support can be expanded through the use of KeePass plugins. KeePass supports simultaneous access and simultaneous changes to

1734-419: A pointer to the respective object. Due to their special handling of the equality operator, strings will nevertheless behave as if they were values, for all practical purposes. You can even use them as case labels. Where necessary, value types will be boxed automatically. C# supports a strict Boolean data type , bool . Statements that take conditions, such as while and if , require an expression of

1836-497: A randomized device ID to prevent services from uniquely identifying the device for tracking purposes. The DRM module, once it has been downloaded, is enabled, and disabled in the same manner as other plug-ins . Since version 47, "Google's Widevine CDM on Windows and Mac OS X so streaming services like Amazon Video can switch from Silverlight to encrypted HTML5 video" is also supported. Mozilla justified its partnership with Adobe and Google by stating: Firefox downloads and enables

1938-490: A running KeePass to steal all data when the host is compromised. KeePass cannot prevent password theft and, as Dominik Reichl, the administrator of KeePass, states, "neither KeePass nor any other password manager can magically run securely in a spyware-infected, insecure environment." The password list is saved by default as a .kdbx file, but it can be exported to .txt , HTML , XML and CSV . The XML output can be used in other applications and re-imported into KeePass using

2040-467: A shared password file by multiple computers (often by using a shared network drive), however there is no provisioning of access per-group or per-entry. As of May 2014, there are no plugins available to add provisioned multi-user support, but there exists a proprietary password server (now titled Keepass Hub, formerly known as Pleasant Password Server ) that is compatible with the KeePass client and includes provisioning. KeePass can minimize itself and type

2142-591: A sharp symbol ( U+266F ♯ MUSIC SHARP SIGN ( ♯ )), the number sign ( U+0023 # NUMBER SIGN ( # )) was chosen to approximate the sharp symbol in the written name of the programming language. This convention is reflected in the ECMA-334 C# Language Specification. The "sharp" suffix has been used by a number of other .NET languages that are variants of existing languages, including J# (a .NET language also designed by Microsoft that

2244-434: A single attribute of a class. A C# namespace provides the same level of code isolation as a Java package or a C++ namespace , with very similar rules and features to a package . Namespaces can be imported with the "using" syntax. In C#, memory address pointers can only be used within blocks specifically marked as unsafe , and programs with unsafe code need appropriate permissions to run. Most object access

2346-496: A single method to cover all interfaces and if necessary specific methods for each interface. However, unlike Java, C# supports operator overloading . C# also offers function overloading (a.k.a. ad-hoc-polymorphism). Since version 2.0, C# offers parametric polymorphism , i.e. classes with arbitrary or constrained type parameters, e.g. List<T> , a variable-sized array which only can contain elements of type T . There are certain kinds of constraints you can specify for

2448-487: A temporary, random session key. Access to the database is restricted by a master password or a key file. Both methods may be combined to create a "composite master key". If both methods are used, then both must be present to access the password database. KeePass version 2.x introduces a third option—dependency upon the current Windows user. KeePass encrypts the database with the AES , Twofish or ChaCha20 symmetric cipher, where

2550-461: A trademark claim from Phoenix Technologies . The replacement name, Firebird, provoked an intense response from the Firebird database software project. The Mozilla Foundation reassured them that the browser would always bear the name Mozilla Firebird to avoid confusion. After further pressure, Mozilla Firebird became Mozilla Firefox on February 9, 2004. The name Firefox was said to be derived from

2652-616: A type that implements the true operator, such as the Boolean type. While C++ also has a Boolean type, it can be freely converted to and from integers, and expressions such as if (a) require only that a is convertible to bool, allowing a to be an int, or a pointer. C# disallows this "integer meaning true or false" approach, on the grounds that forcing programmers to use expressions that return exactly bool can prevent certain types of programming mistakes such as if (a = b) (use of assignment = instead of equality == ). C#

2754-662: A web page used too many resources, the entire Firefox process would hang or crash, affecting all tabs. Additionally, any exploit could easily access system resources, including user files. Between 2008 and 2012, most browsers shifted to a multiprocess architecture, isolating high-risk processes like rendering, media, GPU, and networking. However, Firefox was slower to adopt this change. It wasn't until 2015 that Firefox started its Electrolysis (e10s) project to implement sandboxing across multiple components. This rewrite relied on interprocess communication using Chromium 's interprocess communication library and placed various component including

2856-508: A whole; its usage then declined in competition with Google Chrome . As of July 2024 , according to StatCounter , it had a 6.5% usage share on traditional PCs (i.e. as a desktop browser), making it the fourth-most popular PC web browser after Google Chrome (65%), Microsoft Edge (13%), and Safari (9.0%). The project began as an experimental branch of the Mozilla project by Dave Hyatt , Joe Hewitt , and Blake Ross . They believed

2958-450: Is 0, DoH is disabled; 1 activates DoH in addition to unencrypted DNS; 2 causes DoH to be used before unencrypted DNS; to use only DoH, the value must be 3. By setting network.trr.uri to the URL, special Cloudflare servers will be activated. Mozilla has a privacy agreement with this server host that restricts their collection of information about incoming DNS requests. On May 21, 2019, Firefox

3060-636: Is a free and open source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation . It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 and later versions of Windows , macOS , and Linux . Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD , OpenBSD , NetBSD , and other platforms. It

3162-439: Is a general-purpose high-level programming language supporting multiple paradigms . C# encompasses static typing, strong typing , lexically scoped , imperative , declarative , functional , generic , object-oriented ( class -based), and component-oriented programming disciplines. The principal inventors of the C# programming language were Anders Hejlsberg , Scott Wiltamuth, and Peter Golde from Microsoft . It

3264-446: Is a member of a class that can be invoked as a function (a sequence of instructions), rather than the mere value-holding capability of a field (i.e. class or instance variable ). As in other syntactically similar languages, such as C++ and ANSI C , the signature of a method is a declaration comprising in order: any optional accessibility keywords (such as private ), the explicit specification of its return type (such as int , or

3366-524: Is also available for Android and iOS . However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser . Firefox is the spiritual successor of Netscape Navigator , as the Mozilla community

The original implementation of Eiffel for .NET was called Eiffel#, a name retired since the full Eiffel language is now supported. The suffix has also been used for libraries , such as Gtk# (a .NET wrapper for GTK and other GNOME libraries) and Cocoa# (a wrapper for Cocoa ). The core syntax of

3672-632: Is designed to be compatible with Google Chrome and Microsoft Edge extension systems. Firefox previously supported add-ons using the XUL and XPCOM APIs, which allowed them to directly access and manipulate much of the browser's internal functionality. As compatibility was not included in the multi-process architecture, XUL add-ons have been deemed Legacy add-ons and are no longer supported on Firefox 57 "Quantum" and newer. Mozilla has occasionally installed extensions for users without their permission. This happened in 2017 when an extension designed to promote

3774-727: Is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named Firefox Quantum . A Mozilla executive stated that Quantum was the "biggest update" to the browser since version 1.0. Unresponsive and crashing pages only affect other pages loaded within the same process. While Chrome uses separate processes for each loaded tab, Firefox distributes tabs over four processes by default (since Quantum), in order to balance memory consumption and performance. The process count can be adjusted, where more processes increase performance at

3876-455: Is done through safe object references, which always either point to a "live" object or have the well-defined null value; it is impossible to obtain a reference to a "dead" object (one that has been garbage collected), or to a random block of memory. An unsafe pointer can point to an instance of an unmanaged value type that does not contain any references to objects subject to garbage collections such as class instances, arrays or strings. Code that

However, the introduction of the feature was then delayed so Mozilla developers could "collect and analyze data on the effect of blocking some third-party cookies." Mozilla also collaborated with Stanford University 's "Cookie Clearinghouse" project to develop

4080-740: Is more type safe than C++. The only implicit conversions by default are those that are considered safe, such as widening of integers. This is enforced at compile-time, during JIT , and, in some cases, at runtime. No implicit conversions occur between Booleans and integers, nor between enumeration members and integers (except for literal 0, which can be implicitly converted to any enumerated type). Any user-defined conversion must be explicitly marked as explicit or implicit, unlike C++ copy constructors and conversion operators, which are both implicit by default. C# has explicit support for covariance and contravariance in generic types, unlike C++ which has some degree of support for contravariance simply through

4182-490: Is not marked as unsafe can still store and manipulate pointers through the System.IntPtr type, but it cannot dereference them. Managed memory cannot be explicitly freed; instead, it is automatically garbage collected. Garbage collection addresses the problem of memory leaks by freeing the programmer of responsibility for releasing memory that is no longer needed in most cases. Code that retains references to objects longer than

4284-550: Is required can still experience higher memory usage than necessary, however once the final reference to an object is released the memory is available for garbage collection. A range of standard exceptions are available to programmers. Methods in standard libraries regularly throw system exceptions in some circumstances and the range of exceptions thrown is normally documented. Custom exception classes can be defined for classes allowing handling to be put in place for particular circumstances as needed. The syntax for handling exceptions

4386-482: Is the following: Depending on your plans, the "finally" part can be left out. If error handling is not required, the (Exception ex) parameter can be omitted as well. Also, there can be several "catch" parts handling different kinds of exceptions. Checked exceptions are not present in C# (in contrast to Java). This has been a conscious decision based on the issues of scalability and versionability. Unlike C++ , C# does not support multiple inheritance , although

4488-686: The IEnumerable<;T> interface is implemented on the object. This includes XML documents, an ADO.NET dataset, and SQL databases. + Using LINQ in C# brings advantages like IntelliSense support, strong filtering capabilities, type safety with compile error checking ability, and consistency for querying data over a variety of sources. There are several different language structures that can be utilized with C# and LINQ and they are query expressions, lambda expressions, anonymous types, implicitly typed variables, extension methods, and object initializers.

Because the SVG font tests were removed from the Acid3 test in September 2011, Firefox 4 and greater scored 100/100. Firefox also implements "Safe Browsing," a proprietary protocol from Google used to exchange data related with phishing and malware protection. Firefox supports

4692-456: The Java programming language in 1994, and Bill Joy , a co-founder of Sun Microsystems , the originator of Java, called C# an "imitation" of Java; Gosling further said that "[C# is] sort of Java with reliability, productivity and security deleted." In July 2000, Hejlsberg said that C# is "not a Java clone" and is "much closer to C++" in its design. Since the release of C# 2.0 in November 2005,

4794-487: The LINQ extensions released with C# 3.0 and its supporting framework of lambda expressions , extension methods , and anonymous types . These features enable C# programmers to use functional programming techniques, such as closures , when it is advantageous to their application. The LINQ extensions and the functional imports help developers reduce the amount of boilerplate code that is included in common tasks like querying

4896-563: The WHATWG such as client-side storage, and the canvas element . These standards are implemented through the Gecko layout engine, and SpiderMonkey JavaScript engine. Firefox 4 was the first release to introduce significant HTML5 and CSS3 support. Firefox has passed the Acid2 standards-compliance test since version 3.0. Mozilla had originally stated that they did not intend for Firefox to pass

4998-452: The authenticity of the data is ensured using a HMAC-SHA-256 hash of the ciphertext (Encrypt-then-MAC construction). KeePass at one time had a paste-once functionality, where after a single paste operation, the clipboard would be cleared automatically, but this was removed in version 2.x due to incompatibility and insufficient effectiveness.

Each CDM runs in a separate container called a sandbox and you will be notified when a CDM is in use. You can also disable each CDM and opt-out of future updates and that it is "an important step on Mozilla's roadmap to remove NPAPI plugin support." Upon the introduction of EME support, builds of Firefox on Windows were also introduced that exclude support for EME. The Free Software Foundation and Cory Doctorow condemned Mozilla's decision to support EME. From its inception, Firefox

5202-520: The C# and Java languages have evolved on increasingly divergent trajectories, becoming two quite different languages. One of the first major departures came with the addition of generics to both languages, with vastly different implementations. C# makes use of reification to provide "first-class" generic objects that can be used like any other class, with code generation performed at class-load time. Furthermore, C# has added several major features to accommodate functional-style programming, culminating in

5304-470: The C# language is similar to that of other C-style languages such as C, C++ and Java, particularly: Some notable features of C# that distinguish it from C, C++, and Java where noted, are: By design, C# is the programming language that most directly reflects the underlying Common Language Infrastructure  (CLI). Most of its intrinsic types correspond to value-types implemented by the CLI framework. However,

Firefox Hello was an implementation of WebRTC , added in October 2014, which allows users of Firefox and other compatible systems to have a video call, with the extra feature of screen and file sharing by sending a link to each other. Firefox Hello was scheduled to be removed in September 2016. Former features include

5508-485: The Mozilla Suite to Firefox and Thunderbird . The Firefox project has undergone several name changes. The nascent browser was originally named Phoenix, after the mythical bird that rose triumphantly from the ashes of its dead predecessor (in this case, from the "ashes" of Netscape Navigator , after it was sidelined by Microsoft Internet Explorer in the " First Browser War "). Phoenix was renamed in 2003 due to

5610-475: The Servo team transferring ownership of the project to the Linux Foundation . When Firefox initially released, it used a custom script permission policy where scripts that were signed by the page could gain access to higher privilege actions such as the ability to set a user's preferences. However, this model was not widely used and was later discontinued by Firefox. Modern day Firefox instead follows

On January 13, 2022, an issue with Firefox's HTTP/3 implementation resulted in a widespread outage for several hours. On September 26, 2023, Firefox 118.0 introduced on-device translation of web page content. On January 23, 2024, along with the release of Firefox 122.0, Mozilla introduced an official APT repository for Debian -based Linux distributions . Features of

Firefox implements many web standards , including HTML4 (almost full HTML5 ), XML , XHTML , MathML , SVG 1.1 (full), SVG 2 (partial), CSS (with extensions), ECMAScript ( JavaScript ), DOM , XSLT , XPath , and APNG (Animated PNG ) images with alpha transparency . Firefox also implements standards proposals created by

These improvements came in the wake of decreasing market share to Google Chrome , as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing add-ons for Firefox to be made incompatible with newer versions, in favor of a new extension system that

Additionally, you can specify a variable-sized argument list by applying the params keyword to the last parameter. Certain specific kinds of methods, such as those that simply get or set a field's value by returning or assigning it, do not require an explicitly stated full signature, but in

The KeeForm extension fills in user details into website form fields automatically. It is available for Mozilla Firefox , Google Chrome, and Microsoft Edge. Internet Explorer also has a browser integration toolbar available. KeePass features a built-in password generator that generates random passwords. Random seeding can be done through user input (mouse movement and random keyboard input). KeePass has

6222-632: The commercial requirements of Netscape 's sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser. To combat what they saw as the Mozilla Suite 's software bloat , they created a standalone browser, with which they intended to replace the Mozilla Suite. Version 0.1 was released on September 23, 2002. On April 3, 2003, the Mozilla Organization announced that it planned to change its focus from

On Windows Vista and later versions, passwords are encrypted in process memory using Windows Data Protection API , which allows storing the key for memory protection in a secure, non-swappable memory area. On previous Windows systems, KeePass falls back to using the ARC4 cipher with

6426-414: The cost of memory, therefore suitable for computers with larger RAM capacity. On May 3, 2019, the expiry of an intermediate signing certificate on Mozilla servers caused Firefox to automatically disable and lock all browser extensions (add-ons). Mozilla began the roll-out of a fix shortly thereafter, using their Mozilla Studies component. Support for Adobe Flash was dropped on January 6, 2021, with

In interviews and technical papers, he has stated that flaws in most major programming languages (e.g. C++ , Java , Delphi , and Smalltalk ) drove the fundamentals of the Common Language Runtime (CLR), which, in turn, drove the design of the C# language. James Gosling , who created

6732-423: The developer tools for testing purposes. Beginning with Firefox 48, all extensions must be signed by Mozilla to be used in release and beta versions of Firefox. Firefox 43 blocked unsigned extensions but allowed enforcement of extension signing to be disabled. All extensions must be submitted to Mozilla Add-ons and be subject to code analysis in order to be signed, although extensions do not have to be listed on

6834-608: The development and release model changed into a "rapid" one; by the end of 2011 the stable release was version 9, and by the end of 2012 it reached version 17. Major redesigns of its graphical user interface occurred on versions 4.0 ( Strata ) in March 2011, 29.0 ( Australis ) in April 2014, 57.0 ( Photon ) in November 2017, and 89.0 ( Proton ) in June 2021. In 2016, Mozilla announced a project known as Quantum , which sought to improve Firefox's Gecko engine and other components to improve

However, a separate plugin provides Twofish as an encryption algorithm in KeePass 2.x. In KeePass 1.x (KDB database format), the integrity of the data is checked using a SHA-256 hash of the plaintext, whereas in KeePass 2.x (KDBX database format),

7038-478: The following: Firefox 1.0 was released for Windows 95 , as well as Windows NT 4.0 or later. Some users reported the 1.x builds were operable (but not installable) on Windows NT 3.51 . The version 42.0 release includes the first x64 build. It required Windows 7 or Server 2008 R2 . Starting from version 49.0, Firefox for Windows requires and uses the SSE2 instruction set. In September 2013, Mozilla released

7140-592: The four most widely used password managers (alongside 1Password , Dashlane and LastPass ), being "popular among tech enthusiasts" and offering the same level of security as non-free competitors. A 2019 Independent Security Evaluators study described KeePass as well as other widely used password managers as being unable to control Windows 10 's tendency to leave passwords in cleartext in RAM after they are displayed using Windows controlled GUI. In addition, several GitHub projects (KeeFarce, KeeThief, Lazanga) specifically attack

7242-404: The general case, the definition of a class includes the full signature declaration of its methods. Like C++, and unlike Java, C# programmers must use the scope modifier keyword virtual to allow methods to be overridden by subclasses. Unlike C++, you have to explicitly specify the keyword override when doing so. This is supposed to avoid confusion between overriding and newly overloading

7344-557: The in-house Pontoon localization platform. The first official release in November 2004 was available in 24 different languages and for 28 locales . In 2019, Mozilla released Project Fluent a localization system that allows translators to be more flexible with their translation than to be constrained in one-to-one translation of strings. As of November 2024 the supported versions of Firefox are available in 97 locales (88 languages). There are desktop versions of Firefox for Microsoft Windows, macOS, and Linux, while Firefox for Android

7446-503: The information of the currently selected entry into dialogs, webforms, etc. KeePass has a global auto-type hot key. When KeePass is running in the background (with an unlocked database) and user presses down the hotkey, it looks up the selected (or correct) entry and enters every login and/or password characters sequence. All fields, such as title, username, password, URL, and notes, can be drag and dropped into other windows. Windows clipboard handling allows double-clicking on any field of

7548-576: The integrated pop-up blocker , tabbed browsing , and an extension mechanism for adding functionality. Although these features have already been available for some time in other browsers such as the Mozilla Suite and Opera , Firefox was the first of these browsers to have achieved large-scale adoption. Firefox attracted attention as an alternative to Internet Explorer , which had come under fire for its alleged poor program design and insecurity—detractors cite IE's lack of support for certain Web standards, use of

7650-526: The keyword delegate . Like the Qt framework's pseudo-C++ signal and slot , C# has semantics specifically surrounding publish-subscribe style events, though C# uses delegates to do so. C# offers Java-like synchronized method calls, via the attribute [MethodImpl(MethodImplOptions.Synchronized)] , and has support for mutually-exclusive locks via the keyword lock . C# supports classes with properties . The properties can be simple accessor functions with

7752-402: The keyword var , and implicitly typed arrays with the keyword new[] followed by a collection initializer. Its type system is split into two families: Value types, like the built-in numeric types and user-defined structs, which are automatically handed over as copies when used as parameters, and reference types, including arrays, instances of classes, and strings, which only hand over

7854-403: The keyword void if no value is returned), the name of the method, and finally, a parenthesized sequence of comma-separated parameter specifications, each consisting of a parameter's type, its formal name and optionally, a default value to be used whenever none is provided. Different from most other languages, call-by-reference parameters have to be marked both at the function definition and at

7956-475: The language is C# 13.0, which was released in 2024 in .NET 9.0. The Ecma standard lists these design goals for C#: During the development of the .NET Framework , the class libraries were originally written using a managed code compiler system named Simple Managed C (SMC). In January 1999, Anders Hejlsberg formed a team to build a new language at the time called Cool, which stood for " C-like Object Oriented Language". Microsoft had considered keeping

8058-432: The language specification does not state the code generation requirements of the compiler: that is, it does not state that a C# compiler must target a Common Language Runtime, or generate Common Intermediate Language (CIL), or generate any other specific format. Some C# compilers can also generate machine code like traditional compilers of C++ or Fortran . C# supports strongly, implicitly typed variable declarations with

8160-462: The name "Cool" as the final name of the language, but chose not to do so for trademark reasons. By the time the .NET project was publicly announced at the July 2000 Professional Developers Conference , the language had been renamed C#, and the class libraries and ASP.NET runtime had been ported to C#. Hejlsberg is C#'s principal designer and lead architect at Microsoft, and was previously involved with

8262-690: The operating system, was considered a safer alternative since it was less likely to have issues that could completely compromise a computer. This led to a significant increase in Firefox's popularity during the early 2000s as a more secure alternative. Moreover, Firefox was considered to have fewer actively exploitable security vulnerabilities compared to its competitors. In 2006, The Washington Post reported that exploit code for known security vulnerabilities in Internet Explorer were available for 284 days compared to only nine days for Firefox before

8364-455: The password list to copy its value to the Windows clipboard. KeePass may be configured to randomize characters' input sequence to make it harder to log keystrokes . The features is called Two-Channel Auto-Type Obfuscation (TCATO). KeePass automatically clears the clipboard some time after the user has copied one of their passwords into it. KeePass features protection against clipboard monitors (other applications will not get notifications that

8466-405: The playback of video content protected by HTML5 Encrypted Media Extensions (EME), since version 38. For security and privacy reasons, EME is implemented within a wrapper of open-source code that allows execution of a proprietary DRM module by Adobe Systems —Adobe Primetime Content Decryption Module (CDM). CDM runs within a " sandbox " environment to limit its access to the system and provide it

8568-568: The potentially dangerous ActiveX component, and vulnerability to spyware and malware installation. Microsoft responded by releasing Windows XP Service Pack 2, which added several important security features to Internet Explorer 6. Version 1.0 of Firefox was released on November 9, 2004. This was followed by version 1.5 in November 2005, version 2.0 in October 2006, version 3.0 in June 2008, version 3.5 in June 2009, version 3.6 in January 2010, and version 4.0 in March 2011. From version 5 onwards,

8670-476: The problem was fixed. A Symantec study around the same period showed that even though Firefox had a higher number of vulnerabilities, on average vulnerabilities were fixed faster in Firefox than in other browsers during that period. During this period, Firefox used a monolithic architecture , like most browsers at the time. This meant all browser components ran in a single process with access to all system resources . This setup had multiple security issues. If

8772-452: The release of Firefox 85. On June 1, 2021, Firefox's 'Proton' redesign was offered through its stable release channel after being made available in the beta builds. While users were initially allowed to revert to the old design through about:config , the corresponding key-value pairs reportedly stopped working in later builds, resulting in criticism. These included accessibility concerns despite Mozilla's claim to "continue to work with

8874-479: The rendering component in its own sandbox. Firefox released this rewrite in to beta in August 2016, noting a 10–20% increase in memory usage, which was lower than Chrome's at the time. However, the rewrite caused issues with their legacy extension API, which was not designed to work cross-process and required shim code to function correctly. After over a year in beta, the rewrite was enabled by default all users of Firefox in November 2017. In 2012, Mozilla launched

8976-548: The security of existing components. Additionally, the older incompatible extension API was removed in favour of a WebExtension API that more closely resembled Google Chrome's extension system. This broke compatibility with older extensions but resulted in lesser vulnerabilities and a much more maintainable extension system. While the Servo project was intended to replace more parts of the Gecko Engine, this plan never came to fruition. In 2020, Mozilla laid off all developers on

9078-473: The semantics of return types on virtual methods. Enumeration members are placed in their own scope . The C# language does not allow for global variables or functions. All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions. Local variables cannot shadow variables of the enclosing block, unlike C and C++. Metaprogramming can be achieved in several ways: A method in C#

9180-585: The service to be signed. On May 2, 2019, Mozilla announced that it would be strengthening the signature enforcement with methods that included the retroactive disabling of old extensions now deemed to be insecure. Since version 60 Firefox includes the option to use DNS over HTTPS (DoH), which causes DNS lookup requests to be sent encrypted over the HTTPS protocol. To use this feature the user must set certain preferences beginning with "network.trr" (Trusted Recursive Resolver) in about:config : if network.trr.mode

9282-409: The show Mr. Robot was silently added in an update to Firefox. Firefox can have themes added to it, which users can create or download from third parties to change the appearance of the browser. In 2013, Firefox for Android added a guest session mode, which wiped browsing data such as tabs, cookies, and history at the end of each guest session. Guest session data was kept even when restarting

9384-451: The standard same-origin policy permission model that is followed by most modern browsers which disallows scripts from accessing any privileged data including data about other websites. It uses TLS to protect communications with web servers using strong cryptography when using the HTTPS protocol. The freely available HTTPS Everywhere add-on enforces HTTPS, even if a regular HTTP URL

9486-413: The type parameters: Has to be type X ( or one derived from it ), has to implement a certain interface, has to be a reference type, has to be a value type, has to implement a public parameterless constructor . Most of them can be combined, and you can specify any number of interfaces. C# has the ability to utilize LINQ through the .NET Framework. A developer can query a variety of data sources, provided

9588-439: The use of KeePass more efficiently on Linux. According to the utility's author, KeePass was one of the first password management utilities to use security-enhanced password edit controls, in this case one called CSecureEditEx. The author makes several claims regarding the security of the control and its resistance to password revealing utilities; however, the author does not cite or make any references to any third-party testing of

9690-427: The websites users visit. Also known as state partitioning or "total cookie protection", SmartBlock works via a feature in the browser that isolates data from each site visited by the user to ensure that cross-site scripting is very difficult if not impossible. The feature also isolates local storage, service workers and other common ways for sites to store data. Firefox is a widely localized web browser. Mozilla uses

9792-514: Was created by Netscape in 1998, before its acquisition by AOL . Firefox was created in 2002 under the codename "Phoenix" by members of the Mozilla community who desired a standalone browser rather than the Mozilla Application Suite bundle. During its beta phase, it proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft 's then-dominant Internet Explorer 6 . It

9894-429: Was first widely distributed in July 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO / IEC (ISO/IEC 23270 and 20619 ) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio , both of which were closed-source . At the time, Microsoft had no open-source products. Four years later, in 2004, a free and open-source project called Mono began, providing

9996-491: Was made due to the fact the JavaScript was being used across a majority of websites on the web and disabling JavaScript could potentially have untoward repercussions on inexperienced users who are unaware of its impact. Firefox also cited the fact that extensions like NoScript , that can disable JavaScript in a more controlled fashion, were widely available. The following release added the ability to disable JavaScript through

10098-466: Was positioned as a security-focused browser. At the time, Internet Explorer , the dominant browser, was facing a security crisis. Multiple vulnerabilities had been found, and malware like Download.Ject could be installed simply by visiting a compromised website. The situation was so bad that the US Government issued a warning against using Internet Explorer. Firefox, being less integrated with

10200-455: Was released on November 9, 2004, and challenged Internet Explorer 's dominance with 60 million downloads within nine months. In November 2017, Firefox began incorporating new technology under the code name " Quantum " to promote parallelism and a more intuitive user interface . Firefox usage share grew to a peak of 32.21% in November 2009, with Firefox 3.5 overtaking Internet Explorer 7 , although not all versions of Internet Explorer as

10302-429: Was then approved under ISO/IEC 23270:2006. The 23270:2006 is withdrawn under 23270:2018 and approved with this version. Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation. That project was not completed, and the name was later reused. The name "C sharp" was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made

10404-453: Was updated to include the ability to block scripts that used a computer's CPU to mine cryptocurrency without a user's permission, in Firefox version 67.0. The update also allowed users to block known fingerprinting scripts that track their activity across the web, however it does not resist fingerprinting on its own. In March 2021, Firefox launched SmartBlock in version 87 to offer protection against cross-site tracking , without breaking
