I have FF 4.0. I would like to keep up with it as it improves. In the meantime, 3.6 was faster switching tabs and loading most sites. How do I load FF 3.6 and put it on a different profile.

Chosen solution

Do a custom install and install each version in its own program folder to use multiple Firefox versions.

Create a new profile exclusively for each Firefox version and create a desktop shortcut with -P "profile" appended to the target to launch each Firefox version with its own profile.
