Mozilla has released the final planned beta of Firefox 4.0. The open source browser maker hopes to have the final version out before the end of March. They’re saying final planned beta because Mozilla subscribes to the “when it’s ready” mantra. In other words, Mozilla won’t actually ship until they agree that the code is actually stable and ready for mass consumption.
The list of bugs fixed with beta 12 is upwards of 650 and most of them deal with stability, performance, and security fixes.
I will be testing beta 12 on Linux, OS X and Windows to primarily determine how its overall fit and finish compare to beta 11. I am very impressed with all of the new features the browser has in store. I am going to be specifically focused on Panorama and overall stability.
