Huh! Mozilla is back and again with an another release date. As per new schedule, Mozilla is planning to release final version of Firefox 4 on Mrach 22! But if they come across any new issue RC2 will be released soon.
Mozilla will soon stop shipping Firefox 3.6 to its users to clear path for Firefox 4.0. Firefox 4 Beta 9 may be released before this year end as it has only 49 blockers to be fixed.
