Firefox 4 Released on 22 March


From Mozilla:-
Today’s triage session concluded with all systems go for a Firefox 4 launch on March 22nd. We will continue to have triage sessions on a daily basis to watch for major issues; however, at this point, we’ve concluded RC1 will become Firefox 4 final.Firefox is the most popular browser for people who enjoy modding and adding plug-ins to use online.  In this regard it’s very different from it’s main rival Chrome which focuses on stripped-down simplicity.  Indeed the new IE9 has gone Chrome’s way so this could enable Firefox to regain some of the market share it’s lost in the last couple of years.
The final version ofd the browser will be available simultaneously for WIndows, Mac and Linux and it adds a few features that we’ve recently seen in other browsers including hardware-accellerated graphics rendering.
It’s an exciting time for the web browser industry as the war is well and truly back on after a few years of not very much going on at all.
