Mozilla has made Firefox 4 available to download for Windows, Mac OS X and Linux.

Mozilla released 12 betas of Firefox 4 and fixed more than 7,000 bugs before releasing the final version.

"Firefox 4 is the fastest Firefox yet. With dramatic speed and performance advancements across the board, Firefox is between two and six times faster than previous releases. Major enhancements to the JavaScript engine make everything from start-up time and page load speed to graphics and JavaScript performance screaming fast in Firefox," said Mozilla in a blog post.

The latest version includes security features, 'do not track' and 'content security policy'. Firefox Sync allows users to access history, bookmarks, open tabs and passwords across computers and mobile devices. The 'app tab' feature permanently links to favourite sites, such as Twitter.

Firefox also supports web technologies, including HTML5.

Mozilla says Firefox 4 will be available on Android and Maemo devices soon.
