Mozilla Firefox 5 is now available for download just three months after the release of Firefox 4. Firefox 5 almost looks like Firefox 4 because rather than making a whole new look, Mozilla has added better support for web standards, fixed some bugs and some performance issues. See the list of changes in Firefox 5.
Mozilla Firefox 5 is faster than Firefox 4 with some great enhancements. You can download Firefox 5 from Official Mozilla site or just navigate to Help>>About Firefox.
