Mozilla in a low key move has posted the finished version of Firefox 5 (direct links: Mac, Linux 32-bit, Linux 64-bit, Windows). The new version is the first of a now Chrome-like fast schedule and focuses mostly on minor improvements over Firefox 4. It now recognizes CSS transitions, has better support for HTML5 and its Canvas mode, and is tackling privacy with a more prominent Do Not Track option.
Many fixes are also underneath, such as better performance for background tabs and integration with Linux. WebGL, spelling checks, and overall network and memory use have been given boosts as well.
The final release is officially due to go public on June 21 but shouldn't be significantly different than the version posted on Saturday. Firefox 6 is already in alpha and could be in beta as soon as two weeks from now.
