Firefox 6.0 Released
Firefox 6.0 is officially released despite the final build got leaked out 2 days ago. Firefox 6.0 is released 2 months after Firefox 5.0 and 5 months after Firefox 4.0. Soon, people will just lose track of version number and it will no longer be meaningful! I have lost track of what is the current version of Google Chrome!
