Everybody was shocked after seeing Mozilla Firefox’s ambitious Roadmap of releasing Firefox 7 by the end of this year ( 2011 ).  But it seems the Roadmap would be followed and we could see quick releases of next versions soon.

Ahead of time, Mozilla has silently release the Release Candidate of Firefox 5 and the files are up to download on their FTP servers. It hardly been 12 weeks since Firefox 4 release and we already have the final version of the next version of Firefox.
