I have various secure sites I use for work. After upgrading to Firefox 6, some of these sites say they do not support version 6, only version 5 or earlier. I need to return to version 5. If I do an uninstall and then re-install, I have a hunch I will be re-installing 6.

Thank You, Rolf

Mozilla Firefox, Portable Edition

Install Firefox Portable 3.6.20 to use at those web site. It won't affect your current version of Firefox at all.

Check and tell if its working.
