Mozilla Firefox (or simply Firefox) is a free and open-source [21] web browser developed by the Mozilla Foundation and its Subsidiary, the Mozilla Corporation. Firefox is available for Windows, OS X and Linux operating systems, With its mobile versions available for Android and Firefox OS; Where all of These versions use the Gecko layout engine to render web pages, Which implements current and anticipated web Standards. [22] An additional version, Firefox for iOS was released in late 2015, But this version does not use Gecko due to Apple’s Restrictions limiting third-party web browsers to the WebKit-based layout engine built Into iOS.

Firefox Was created in 2002 under the name “Phoenix” by the Mozilla community members wanted a standalone browser WHO Rather than the Mozilla Application Suite bundle. Even During Its beta phase, Firefox provede To Be Popular With its testers and Was praised for Its speed, security and add-ons compared to Microsoft’s crack-dominant Internet Explorer 6 Firefox was released in November 2004 [23] and Was Highly Successful with 60 million downloads Within nine months, Which Was The first time Internet Explorer’s dominance That Was Challenged. [24] Firefox is considered the spiritual Successor of Netscape Navigator, [25] nor the Mozilla community Was created by Netscape in 1998 Before Their acquisition by AOL. [26]

Firefox usage Grew to a peak of 32% at the end of 2009 [27] version 3.5 temporarily Making the World’s Most popular browser. [28] [29] Usage pointed declined in competition with Chrome [27] As of January 2016, Firefox has between 9% and 16% of Worldwide usage as a “desktop” browser, Making it the second Most popular web browser. [30] [31] [ 32] [33] [34] Firefox is still the browser Most popular in Cuba, Eritrea and Germany, with 85.93% [35] and 79.39% [36] [37] and 38.36%, [38] [39] of the market share, respectively. It is Also the Most popular desktop browser in Many other African Countries. [40] According to Mozilla, as of December 2014 There were half a billion Firefox users around the world. [41] With declining Internet Explorer, Firefox reached second place in February 2016, as a desktop browser.
Began The Firefox project as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt and Blake Ross. They believed the commercial Requirements of Netscape’s sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser. [43] To combat what broke the saw as the Mozilla Suite’s software bloat, They created a stand-alone browser, with Which They intended to replace the Mozilla Suite. [44] On April 3, 2003, the Mozilla Organization Announced That broke the developer’s Planned to change focus from the Mozilla Suite to Firefox and Thunderbird. [45] The community-driven SeaMonkey Eventually Replaced Was Formed and the Mozilla Application Suite in 2005.
The Firefox project has undergone Several name changes. I Was Originally titled Phoenix, Which Carried the implication of the mythical firebird dried rose triumphantly from the ashes of Its dead predecessor, in this case from the “ashes” of Netscape Navigator after it hadd been Killed off by Microsoft’s Internet Explorer in the “First browser war “. Was Phoenix renamed due to trademark Issues with Phoenix Technologies; the replacement name, Firebird, Provoked an intense response from the Firebird database software project. [46] [47] In response, the Mozilla Foundation Would Stated That the browser always bear the name Mozilla Firebird to Avoid confusion. After further pressure, on February 9, 2004, Mozilla Firebird became Mozilla Firefox. [48] The name Firefox Was Said To Be derived from a nickname of the red panda, [49] [50] Which became the mascot for the Newly named project. For the abbreviation of Firefox, Mozilla prefers Fx or fx, though it is Often abbreviated as FF. [51]

The Firefox project Went through Many versions Before the version 1.0 was released on November 9, 2004.
Features include tabbed browsing, spell checking, incremental find, live bookmarking, Smart Bookmarks, a download manager, private browsing, location-aware browsing (also known as “geolocation”) based on a Google service [52] and an Integrated search system That uses Yahoo! Search, Which is a front end of Microsoft search engine Bing, by default in Most localizations. [53] Additionally, Firefox Provides an environment for web developers in Which They Can use built-in tools, Such as the Error Console or the DOM Inspector, or extensions, Such as Firebug and more Recently there has been an integration feature with Pocket. 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 is scheduled to swear removed in September 2016. [54]

Functions Can Be added through add-ons created by third-party developers. Add-ons are Primarily Implemented by Means of the XUL and XPCOM APIs, say Which Allow to directly access and manipulate much of the browser’s internal functionality. On August 21, 2015, Firefox developers Announced That due to Planned changes to Firefox’s internal operations, Including the Planned Implementation of a new multi-process architecture codenamed “Electrolysis” ( “E10s” Introduced to Some users in version 48), Firefox Adopted a new architecture known as WebExtensions extension, available to destop version and Firefox for Android (considered stable in version 48). WebExtensions uses HTML and JavaScript APIs and is Designed To Be Similar to the Google Chrome [55] and Microsoft Edge extension systems, and run Within a multi-process environment, soft does not enable the same level of access to the browser. Solutions Will Be Available to Allow older add-ons to Operate Within the new architecture, soft by 2017 XPCOM and XUL add-ons Will swear no longer supported. [56]

Can Firefox themes have added to it, so Firefox users Can experience in a more personal way. There are websites Where Can users create and download personalized themes, with developer’s choice of colors and images. Can this make the experience of using Firefox more fun compared to other web browsers That will not offer custom-built themes. Howevera, Mozilla has Announced Its Intention to discontinue Firefox themes. [57] The Firefox add-on website Also gives users the Ability to add other applications Such as games, ad-blockers, screenshot Many other useful apps and apps.

Firefox implements Many Web Standards, Including HTML4 (almost full HTML5), XML, XHTML, MathML, SVG 2 (partial), [59] [60] CSS (with extensions), [61] ECMAScript (JavaScript), DOM, XSLT, XPath, and APNG (Animated PNG) images with alpha Transparency. [62] Firefox Also implements Standards created by the WHATWG Proposals Such as client-side storage, [63] [64] and canvas element. [65] These Standards are Implemented through the Gecko layout engine, and Spidermonkey JavaScript engine.

Firefox has passed Is the Acid2 SINCE Standards-compliance test version 3.0. [66] Mozilla hadd Originally Stated That They did not intend for Firefox to pass the acid3 test fully Because They believed That the SVG fonts part of the test hadd Become outdated and irrelevant, due to WOFF being Agreed upon as a standard by all major browser makers. [ 67] Because the SVG font tests acid3 Were removed from the test in September 2011, Firefox 4 and Greater scored 100/100. [68] [69]

Also Firefox implements [70] a proprietary protocol [71] from Google called “Safe Browsing”, used to exchange data related with phishing and malware protection.

Since version 38 on Windows Vista and newer, Firefox supports the playback of video content protected by HTML5 Encrypted Media Extensions (EME). 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). Within CDM runs a “sandbox” Its environment to limit access to the system, and Provide it a randomized device to Prevent ID 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, [72] “Google’s Widevine CDM on Windows and Mac OS X so streaming services like Amazon Video Can switch from Silverlight to HTML5 video encrypted” Also supported is.

Firefox downloads and Enables the Adobe Primetime and Google Widevine CDMs by default to give users a smooth experience on sites requir That DRM. Each CDM Separate runs in a 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 futures updates

– Watch DRM content on Firefox [73]
and That it is “an Important step on Mozilla’s roadmap to remove NPAPI plugin support.” [74] Upon the introduction of EME support, builds of Firefox on Windows Were Also Introduced That exclude support for EME.
Firefox uses a sandbox security model, [77] and limits scripts from Accessing data from other websites based on the Same-Origin policy. [78] It Also Provides support for smart cards to web applications, for authentication Purposes. [79] It uses SSL / TLS to protect communications with web servers using strong cryptography When using the HTTPS protocol. [80] The bMerI available HTTPS Everywhere add-on enforces HTTPS, Even If a regular HTTP URL is entered. Firefox now supports HTTP / 2. [81]

The Mozilla Foundation offers a “bug bounty” (US $ 3,000 to US $ 7,500 cash reward) to WHO researchers always discover severe security holes in Firefox. [82] Official guidelines for handling security Vulnerabilities Vulnerabilities discourage early disclosure of so as not to give an advantage attackers Potential in Creating exploits. [83]

Because Firefox has FEWER Generally Vulnerabilities publicly known security than Internet Explorer (see Comparison of web browsers), Improved security is Often cited as a Reason to switch from Internet Explorer to Firefox. [84] [85] [86] [87] The Washington Post Reported That exploit code for known security critical Was Vulnerabilities in Internet Explorer available for 284 days in 2006. In comparison, exploit code for known, critical security Vulnerabilities in Firefox Was Before available for nine days Mozilla issued a patch to Remedy the problem . [88]

A 2006 Symantec study showed that, although Firefox hadd surpassed other browsers in the number of local-confirmed Vulnerabilities That year through September, poke Vulnerabilities Were patched far more Quickly than Those found in other browsers – Firefox’s Vulnerabilities Were fixed on average one day after the Was made available exploit code, as compared to nine days for Internet Explorer. [89] Their Symantec Clarified later statement, Saying That still HAD FEWER Firefox than Internet Explorer Vulnerabilities security, as counted by security researchers. [90]

In 2010 a study of the National Institute of Standards and Technology (NIST), based on data compiled from the National Vulnerability Database (NVD), Firefox Was listed as the fifth Most vulnerable desktop software, with Internet Explorer as the eighth, and Google Chrome as the first. [91]

InfoWorld has cited security Experts Saying that, neither Firefox Becomes more popular, more Vulnerabilities Will Be found, [92] a Claim That Mitchell Baker, president of the Mozilla Foundation, has Denied. “There is this idea That market share alone Will make you have more Vulnerabilities. It is not relational at all,” she said. [93]

In October 2009, Microsoft’s security engineers acknowledged That Was Firefox vulnerable to a security issue found in the ‘Windows Presentation Foundation’ plug-in browser SINCE That February of year. A .NET Framework 3.5 SP1 installed Windows Update hadd Silently the vulnerable Into Firefox plug-in. [94] SINCE This vulnerability has been patched by Microsoft. [95]

As of February 11, 2011, Firefox 3.6 hadd no known unpatched security Vulnerabilities according to SECUNET. [96] Internet Explorer 8 Vulnerabilities hadd five unpatched security, the worst being rated “Less Critical” by SECUNET. [97] That Claims Mozilla Vulnerabilities of Mozilla patched all products are publicly listed. [98]

On January 28, 2013, Mozilla Was recognized as the Most Trusted Internet company for privacy in 2012. [99] This study Was performed by the Ponemon Institute and Was a Result of a survey from more than 100,000 Consumers in the United States.

In February 2013 Were Announced Plans for Firefox 22 to disable third-party cookies by default. Howevera, the introduction of the feature so delayed Was Then Mozilla developers Could “and Analyze collect data on the effect of blocking Some third-party cookies.” Also Mozilla collaborated with Stanford University’s “Cookie Clearinghouse” project to Develop a blacklist and whitelist of sites That Will Be used in the filter. [100] [101]

Version 23, released in August 2013, Followed the lead of Its Competitors by blocking iframe, stylesheet, and script resources from non-HTTPS Served embedded servers on HTTPS pages by default. Additionally, JavaScript Could swear Also no longer disabled through Firefox’s preferences, and JavaScript Was re-enabled automatically for users WHO upgraded to 23 or higher with it disabled. Was the change made due to Its use across the Majority of websites, the Potential repercussions on non-WHO Experienced users are unaware of Its impact, Along with the availability of extensions Such as NoScript, Which Can disable JavaScript in a more controlled fashion. The release added Following the Ability to disable JavaScript through the developer tools for testing Purposes. [102] [103] [104]

In January 2015, TorrentFreak using Firefox Reported That When connected to the Internet using a VPN Can Be a serious security issue due to the browser’s support for WebRTC. [105]

Beginning with Firefox 44, all extensions Signed by hadd to swear an oath used in Mozilla to release and beta versions of Firefox. Firefox 43 blocked unsigned extensions, soft Enforcement of extension Signing allowed to swear disabled. All extensions WOULD BE Submitted to Mozilla Add-ons and eu subject to code analysis in order to swear Signed, although extensions wouldn’t have to swear listed on the service in order to swear Signed.
