In true Mozilla style, Firefox 4 is slimming down so it can run circles around its hulking IE9 and Chrome 10 competitors. But good things really do come in small packages – or at least on paper they do. Mozilla's already talking of a plan to launch an RC2 update soon after the RC1 release, if there are any problems. Optimistic.
Apart from being "sleeker", as Mozilla describes it, a key upgrade to Firefox 4 will be to sync your settings, passwords, bookmarks, history, and even your open tabs across multiple platforms. So when you leave your desktop you can continue on with your laptop from where you left off. So far, no mention of smartphone compatibility, though. Tut, tut.
Other treats include tab organisation, simpler add-on management, HTML 5 support, multitouch interactivity, and they are claiming at least three times faster performance. Oh yeah, they’ve jumped on the bandwagon to support 3D too.
Mozilla Firefox 4 will be available for free download from March 22.
