I'm looking for a way to test websites on multiple versions of Firefox. I reckon at a time only one version of Firefox can be setup on each computer?

I would use MultiFox. I have posted a link below.

I think that this is a good choice because it can run the different versions of FireFox, but also because it can run them at the same time.

I use Browsershots for this. Nothing to install.

You can also use the portable versions of Firefox, and edit your FirefoxPortable.ini file if you wish to run them simulataneously.

Wouldn't that be cumbersome? Anything that allows running it locally on the dev machine? – ymasood Sep 9 '09 at 12:12

+1 for browsershots. It's much easier than installing tonnes of browsers. And once its all done you can download all the screenshots in a zip file. – Sam152 Sep 9 '09 at 12:23
Thanks looks good. :) – ymasood Sep 9 '09 at 12:24
I must agree, Browsershots is the way to go. Don't commit yourself to one browser, either. – Breakthrough Sep 9 '09 at 12:27

You can run multiple versions of firefox simultaneously on the same machine, by using a seperate profile for each one. This blog post goes through how to set it up. (It talks about FF2 & 3, but the same should also work for FF3.5)

Here's what I do personally for testing... run portable firefox (from portable apps) with different versions. Of course the latest 3.5 is native install on my computer, but FF3, FF 2, and FF 1 - I run as portable apps.

they can all run simultaneously too by the way.
