Reverse to old version

I don't know whether your previous version number is stored anywhere on your PC. Firefox 4 and higher look fairly different in the user interface department than Firefox 3.6, so you probably know whether you leaped up from 3.6 to 11. There are two currently supported previous versions you could try if you are unhappy with Firefox 11. By the way, why do want to revert -- what isn't working? ---- There is an "extended release" version of Firefox 10 that will be kept up-to-date with security fixes for a while. It's intended more for businesses that need a high degree of stability, but you can download it here if you like: http://www.mozilla.org/en-US/firefox/organizations/all.html If you prefer Firefox 3.6.28, you can download that here: http://www.mozilla.org/en-US/firefox/all-older
