If you’ve been keeping up with the beta builds and have been using the Beta 8 release (released December 22) then you’re not going to see a lot of changes in Beta 9. In fact, going by the release notes there’s only two changes of any importance highlighted by Mozilla:
> Overhaul of the bookmarks and history code, enabling faster bookmarking and startup performance
> Per-compartment garbage collection is now enabled, reducing work done during complex animations
Other Changes on Firefox 4:
> Nice, fast, robust browser.
> The re-tweaked interface is a nice, and welcome, change. Mozilla’s solution to removing the menu bar and replacing it with a ‘button’ will be familiar to Opera users.
> The revamped Add-on manager is pleasant to use.
> Sync between desktop and mobile is a nice feature but somewhat clunky. > Crash protection makes using Flash, Quicktime and Silverlight a bit nicer to use.
Firefox final will be available in February according to Mozilla, but this release is more of polish to prior released Firefox 4 Beta 8 version and bug fix release. We can expect another beta and then may be release candidate next to follow.
