What is Firefox 3.5? - Definition from WhatIs.com
Part of the Personal computing glossary:

Firefox 3.5 is a version of the Mozilla Foundation's Web browser that was released in June 2009. This version of the browser is said to be twice as fast as Firefox 3 and up to five times as fast as IE8. Other reported improvements include enhanced security measures, better support for third-party add-ons and increased implementation of HTML 5.

New features for this version of Firefox include:

  • Integrated video and audio so no external players or plugins are required.
  • Local storage to enable working in Web applications offline.
  • Geolocation for location-aware browsing.
  • Downloadable fonts.
  • Private browsing and the ability to "forget" specified sites.
  • The ability to select which tabs to restore after a browser crash.

Firefox uses the open source Gecko layout engine and is based on the Mozilla browser from which much of its code was originally derived. The source code for Firefox is free, open source software (FOSS) and is released under a tri-license GPL/LGPL/MPL. Mozilla has released Firefox 3.5 for Windows, Linux, and Mac OS X in a variety of languages.

As of June 2009, Firefox controlled 22.5 percent of the browser market, worldwide.
