firefox 4

Mozilla has just released Firefox 4 FINAL after many BETAs and two release candidates.
"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 startup time to page load speed to graphics and JavaScript performance screaming fast in Firefox".

What is new in Mozilla Firefox 4 final?

In the last weeks we tested the Firefox integration in the Global Menu/AppMenu from its own PPA and the overall Appmenu integration was pleasant with very few bugs.
Just now the Unity Appmenu extension for Mozilla Firefox has landed in Natty Narwhal, making the browsing experience more compact, fixing some bugs and strengthing the Appmenu.
One interesting thing that worth mentioning is that this Unity extension is developed on its own separate package, independent of Firefox (bug targeting and updates will be more efficient and faster).

We've ran some tests (acid3 test and FishIEtank from Microsoft).
