Origins and Lineage

Mozilla Firefox 2 was a version of Mozilla Firefox, a web browser released on October 24, 2006 by the Mozilla Corporation.

Firefox 2 uses version 1.8 of the Gecko layout engine for displaying web pages. The release contained many new features not found in Firefox 1.5, including improved support for Scalable Vector Graphics (SVG) and JavaScript 1.7, as well as user interface changes.

On March 22, 2006, the first alpha version of Firefox 2 (Bon Echo Alpha 1) was released. It featured Gecko 1.8.1 for the first time. Mozilla Firefox 2.0.0.x is the final version supported on Windows NT 4.0 and Windows 98. Mac OS X 10.5 support was added October 18, 2007 with version

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,[1][2] and later merged into the program itself.[3]

Mozilla ended support for Firefox 2 on 18 December, 2008.[4]

Market adoption & usage of Firefox 2

Template:Seealso Template:Firefox usage share

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%."[5]

A Softpedia article, however, noted in July 2007 that "Firefox 2.0 has been also expanding its share constantly in spite of IE7. From just 0.69% in October 2006, Firefox 2.0 is now accounting for 11.07% of the market. Mozilla has even sacrificed version 1.5 of its open source browser for Firefox 2.0. With support cut at the end of June, Firefox 1.5 dropped to just 2.85%."[5][6][6][7][8]

Firefox 2 began to lose notable market share to Firefox 3 within 24 hours after its release, Firefox 3 usage rose from under 1% to over 3% according to Net Applications in that time period.[9] Firefox 2 market share consistently dropped, eventually being surpassed by Firefox 3 in 2008 in the general browser market as the Firefox version with the greatest share, and by early 2009 had dropped under 3 percent.[10]
