In doing so, they’ve released the fourth beta of Firefox 3.6, delivering over 100 fixes from the previous beta and additional security measures.

With its impressive security and customizable features, Firefox has charged ahead of the browser pack, proving the unfailing principle that competition is good for innovation – which, ultimately, is good for the end user.
