Firefox 4 RC is Available for Download

Mozilla has put up the first release candidate of Firefox 4 as promised. Even though the promise was of the 12th beta being the last, the transition over the last few months has been fast-paced and it would be time for skeptics to shed off their doubts of whether Firefox will be able to deliver a version 7 by the end of 2011, as planned in the roadmap. A brand new decisive release system already tells us how Firefox is hellbent on reaching this goal.


A complete list of new features in this RC is outlined at this page. Out of these changes , the remarkable ones are design UI, organizing tabs, managing add-ons and better a syncing UI. Behind the scene changes include better HTML5 support and better WebM support.

It is expected that these changes will put Firefox back in the game and with the agile roadmap ahead; Firefox has a chance of getting back a number of power users it lost to Google Chrome and Opera. Benchmarks say, the new JavaScript rendering engine is 3.5x faster and watching HD WebM videos will be fun. Along with that, there are other ‘not so evident at first’ changes like, 3D capabilities and hardware acceleration (which Opera too got a few days ago). The crash protection on tabs allows Firefox to isolate the rouge tab caused by a crashing plugin. This prevents the complete browser from going down, in case of a tab-crash and saves our important work.
