As promised in FireFox’s new rapid release development cycle, Mozilla released a new version of FireFox web browser today: FireFox 5.0, about three months after the release of FireFox 4.0 on March 22nd, 2011.

Go ahead upgrade your current FireFox or download and install FireFox if you are not using it (really? You are not using FireFox?), and enjoy the security and feature it brings to you.
