How do I backtrack to vers 3.6xx from vers 4? (very slow)
Vers 4 is very slow on my work computer.(not the one I am using now) How do I downgrade to 3.6xx without loosing anything. Or do I have to do an uninstall and reinstall.

Here's the process to roll back:
First, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 4.
You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.
Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details.
Note: I haven't actually tried this myself!
