Mozilla has put Firefox on a speed train as only a week after the previous release there is already a beta 3. Not a problem in my opinion, as it shows steady progress to a really solid release.

With 80+ bugs fixed in this release stability is again the main focus. Not surprisingly as Firefox 3.6 is more or less feature complete. Of course these betas aren't as exciting this way, but they'll surely pay off once the final release is here. However there are two changes, of which one is important for add-on developers: changes to how we allow third party software to integrate with Firefox in order to prevent crashes, and the ability to run scripts asynchronously to speed up page load times.

Existing beta users will receive the update automatically, or can trigger it manually though the Help menu. The full download is available from the web page. The final Firefox 3.6 release is planned for the end of this year.
