Betas of Firefox 3.6.4 were made available starting on April 20, 2010. A preview version of Lorentz, Firefox 3.6.3plugin1, was made available on April 8, 2010. It is named after the Lorentz National Park. The Firefox developers created a new feature called Lorentz. įirefox 3.6.2 was released on March 23, 2010, followed by version 3.6.3 on April 1 which closed some bugs in the ASLR and DEP handling found at the Pwn2Own contest 2010. Coinciding with a proposal to cater to Enterprise users with optional Extended Support Releases beginning in 2012 based upon Firefox 10, Mozilla discontinued support for Firefox 3.6 on Ap with automatic update to Firefox 12 pushed out to compatible devices by June 2012. Soon after 4, much less weight was given to major version numbers, with 6 numbers used by September of that year (4, 5, 6, 7, 8, and 9) compared to 3 in nearly a decade of Firefox development (1, 2 and 3).įirefox versions 4 through 9 had all reached end-of-life status while Mozilla continued supporting Firefox 3.6 with security updates. Firefox 3.6 is the last major version of an official Firefox release to run on PowerPC-based Macintoshes (see TenFourFox for a much-more-recent version of Firefox for PowerPC-based computers running Mac OS X). It was superseded by Firefox 4, released the next year, although Fx 3.6 had a prolonged period of use and version 4 had noted user interface changes. This was to allow users to receive new features more quickly and the dawn of a new roadmap that reflected these changes. As well as receiving major updates, the browser also received minor updates with new features. This release marked the beginning of a new development cycle for Firefox. In this version, support for X BitMap images was dropped. It uses the Gecko 1.9.2 engine (compared to 1.9.1 in Fx 3.5), which improves compliance with web standards. The release's main improvement over Firefox 3.5 is improved performance (due to further speed improvements in the TraceMonkey JavaScript engine). Mozilla Firefox 3.6 is a version of the Firefox web browser released in January 2010.
