Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla Application Suite, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020.
Early versions The project that became Firefox today began as an experimental branch of the Mozilla Suite called m/b (or mozilla/browser). Firefox retains the cross-platform nature of the original Mozilla browser, using the XUL user interface markup language. The use of XUL made it possible to extend the browser's capabilities through the use of extensions and themes. The development and installation processes of these add-ons raised security concerns, and with the release of Firefox 0.9, the Mozilla Foundation opened a Mozilla Update website containing "approved" themes and extensions. The use of XUL sets Firefox apart from other browsers, including other projects based on Mozilla's Gecko layout engine and most other browsers, which use interfaces native to their respective platforms (Galeon and Epiphany use GTK+, K-Meleon uses MFC, and Camino uses Cocoa). Many of these projects started before Firefox, and may have served as inspiration.
Hyatt, Ross, Hewitt and Chanial developed their browser to combat the perceived software bloat of the Mozilla Suite (codenamed, internally referred to, and continued by the community as SeaMonkey), which integrated features such as IRC, mail, news, and WYSIWYG HTML editing into one internet suite. After it was sufficiently developed, binaries for public testing appeared in September 2002 under the name Phoenix. This name carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case Netscape Navigator which lost the "First browser war" to Microsoft's Internet Explorer. The name Mozilla began as the internal codename for the original 1994 Netscape Navigator browser aiming to displace NCSA Mosaic as the world's most popular web browser. The name for this would-be "Mosaic killer" was meant to evoke the building-crushing Godzilla.
Due to continuing pressure from the Firebird community, on February 9, 2004, the project was renamed again to Mozilla Firefox. The name "Firefox" (a reference to the red panda) was chosen for its similarity to "Firebird", and its uniqueness in the computing industry. To ensure that no further name changes would be necessary, the Mozilla Foundation began the process of registering Firefox as a trademark with the United States Patent and Trademark Office in December 2003. This trademark process led to a delay of several months in the release of Firefox 0.8 when the foundation discovered that Firefox had already been registered as a trademark in the UK for Charlton Company software.Class 09: Computer software for use in managed communications and connectivity.

Firefox 1.0
Firefox version 1.0 was released on November 9, 2004. The launch of version 1.0 was accompanied by "a respectable amount of pre-launch fervor" including a fan-organized campaign to run a full-page ad in The New York Times.
Although the Mozilla Foundation had intended to make the Mozilla Suite obsolete and replace it with Firefox, the Foundation continued to maintain the suite until April 12, 2006 because it had many corporate users and was bundled with other software. The Mozilla community (as opposed to the Foundation) continues to release new versions of the suite, using the product name SeaMonkey to avoid confusion with the original Mozilla Suite.
Firefox 1.5
Firefox 1.5 was released on November 30, 2005. Originally, it was planned to have a version 1.1 at an earlier date as the new Firefox version after 1.0, with development on a later version (1.5) in a separate development branch, but during 2005 both branches and their feature sets were merged (the Mozilla Foundation abandoned the 1.1 release plan after the first two alpha builds), resulting in an official release date between the original dates planned for both versions.
Version 1.5 implemented a new Mac-like options interface, the subject of much criticism from Microsoft Windows and Linux users, with a "Sanitize" action to allow someone to clear their privacy-related information without manually clicking the "Clear All" button. In Firefox 1.5, a user could clear all privacy-related settings simply by exiting the browser or using a keyboard shortcut, depending on their settings. Moreover, the software update system was improved (with binary patches now possible). There were also improvements in the extension management system, with a number of new developer features. In addition, Firefox 1.5 had preliminary SVG 1.1 support.as shown in Mozilla's Bugzilla database
Behind the screens, the new version resynchronized the code base of the release builds (as opposed to nightly builds) with the core "trunk", which contained additional features not available in 1.0, as it branched from the trunk around the 0.9 release. As such, there was a backlog of bug fixes between 0.9 and the release of 1.0, which were made available in 1.5.
There were also changes in operating system support. As announced on June 23, 2005, by the Mozilla Foundation, Firefox 1.1, which later became 1.5, and other new Mozilla products have no longer supported Mac OS X v10.1, in order to improve the quality of Firefox releases on Mac OS X v10.2 and above. Firefox 1.5 is the final version to support Windows 95.
Alpha builds of Firefox 1.5 (id est, 1.1a1 and 1.1a2) did not carry Firefox branding; they were labelled "Deer Park" (which was Firefox 1.5's internal codename) and contained a different program icon. This was done to dissuade end-users from downloading preview versions, which are intended for developers only.
Firefox 2
On October 24, 2006, Mozilla released Firefox 2 (code named "Bon Echo" during development). This version included updates to the tabbed browsing environment, the extensions manager, the GUI (graphical user interface), and the find, search and software update engines. It also implemented a new session restore feature, inline spell checking, and an anti-phishing feature which was implemented by Google as an extension and later merged into the program itself. In December 2007, Firefox Live Chat was launched. It allowed users to ask volunteers questions through a system powered by Jive Software, with guaranteed hours of operation and the possibility of help after hours.
Firefox 2.0.0.20 was the final version that could run under an unmodified installation of Windows NT 4.0, Windows 98, and Windows Me. Subsequently, Mozilla Corporation announced it would not develop new versions of Firefox 2 after the 2.0.0.20 release, but continued Firefox 2 development as long as other programs, such as Thunderbird mail client, depended on it. The final internal release was 2.0.0.22, released in late April 2009.
Firefox 2.0 featured updates to tabbed browsing environment, the extensions manager, the GUI, and the find, search, and software update engines; a new session restore feature; inline spell checking; and an anti-phishing feature which was implemented by Google as an extension, and later merged into the program itself. Mozilla ended support for Firefox 2 on December 18, 2008. As one article noted after the release of Firefox 2.0 in October 2006, "IE6 had the lion's share of the browser market with 77.22%. Internet Explorer 7 had climbed to 3.18%, while Firefox 2.0 was at 0.69%." With support cut at the end of June, Firefox 1.5 dropped to just 2.85%."
Firefox 2.x was end-of-lifed in December 2008.Firefox 2.0.0.15 security and stability update now available for download developer.mozilla.org With roughly 26 months of support, only Firefox 3.6 was supported longer. The Gecko 1.8.1 browser core continued to receive patches for projects such as Camino, K-Meleon, and SeaMonkey, even after official Firefox releases had ceased. By 2011, the 1.8.1 core had become obsolete, as major websites dropped support for it by employing newer technologies for presentation and complex scripting. Firefox 3.0 or newer listed. The latter can be resource-intensive with the older core, and users stuck with it should use NoScript The latest legacy NoScript version for Firefox 2.0 and SeaMonkey 1.1 is 1.10 to avoid problems with scripts that take too long to process (at the cost of losing some or all site features beyond basic functionality).
Firefox 3
Firefox 3 was released on June 17, 2008, by the Mozilla Corporation. Firefox 3 uses version 1.9 of the Mozilla Gecko layout engine for displaying web pages. This version fixes many bugs, improves standard compliance, and implements new web APIs. Other new features include a redesigned download manager, a new "Places" system for storing bookmarks and history, and separate themes for different operating systems. While the new functionality of the location bar, dubbed the "Awesomebar", was overall well-received, there were those who did not like it due to user interface and performance changes, so much that extensions were made to revert it. Firefox 3 received CNET Editors' Choice in June 2008.
Firefox 3.0 was developed under the codename Gran Paradiso. This, like other Firefox codenames, is the name of an actual place; in this case the seventh-highest mountain in the Graian Alps where they first came up with the idea. Planning began in October 2006, when the development team asked users to submit feature requests that they wished to be included in Firefox 3. This was followed by several more beta releases in spring 2008 culminating in the June release.
Firefox 3 had more than 8 million unique downloads the day it was released, setting a Guinness World Record. See also: The large number of users attempting to access the Mozilla website on June 17 caused it to become unavailable for at least a few hours, and attempts at upgrading to the new version resulted in server timeouts. The site was not updated for the download of Firefox 3 until 12:00 PDT (19:00 UTC), two hours later than originally scheduled. Gareth Deaves, Records Manager for Guinness World Records, complimented Mozilla, saying, "Mobilizing over 8 million internet users within 24 hours is an extremely impressive accomplishment and we would like to congratulate the Mozilla community for their hard work and dedication."
By July 2008, it held over 5.6% of the recorded usage share of web browsers. Estimates of Firefox 3.0's global market share were generally in the range of 4–5%, and then dropped as users migrated to Firefox 3.5 and later Firefox 3.6. Partially as a result of this, between mid-December 2009 and the end of January 2010, Firefox 3.5 was the most popular browser (when counting individual browser versions), passing Internet Explorer 7.Firefox 3.5 is world's most popular browser, StatCounter says , Nick Eaton. seattlepi blogs. December 21, 2009. Retrieved 2009-12-22. Mozilla ended support for Firefox 3 on March 30, 2010, with the release of 3.0.19.
Firefox 3.5
Firefox 3.5 was released on June 30th, 2009. Firefox 3.5 added the Gecko 1.9.1 engine, support for the <video> and <audio> elements defined in the HTML 5 draft specification, a private browsing mode, native support for JSON and web worker threads, multi-touch support, and an updated logo from the previous releases. The default search engine in Russian language builds was changed to Yandex rather than Google, after a survey of Russian Firefox users indicated they preferred Yandex.
