Mozilla has released the final version of Firefox 9 beta meaning it won't be long before it is confirmed as the next stable version of Firefox.

The latest update features improvements to Javascript that Mozilla claims boosts performance by over 30 percent. Mozilla has also tweaked Javascript with something called Type Inference for faster loading times. The other improvement is greater theme integration and swipe navigation for Mac OS X users.

Mozilla's frequent update policy still isn't popular with users - especially because they don't seem to deliver major improvements and break add-ons. Let's hope when the final version of Firefox 9 is confirmed, the transition will be smoother and the improvements more noticeable.

You can download Firefox 9 beta final for Windows and Mac or just wait for it to update automatically.
