Can I use two different versions of Firefox on the same computer?

I work part time for ChaCha which requires their toolbar addon to work. They have not updated that toolbar yet to be compatible with FF 4.0. I was wondering can I have two different installs of FF (3.6.16) that I use for ChaCha and 4.0 that I use for everything else until ChaCha updates their toolbar?

You can do a custom install and install each version in its own program folder.

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.
