I have Win 7 x64 operating system.

How can I run two different FireFox versions?

I want to be able to run FF3.6 and FF10

But it seems its set up the way that I can only install one of them.

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.

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