Where to download a previous version of firefox?

I want to go back to Firefox 3.6.3 (last version that worked for me!), but cannot find where to download it from?

Firefox needs to make previous version downloads easily available, if they want users to try their iffy upgrades!

I downloaded Firefox 4.0 and it works only for a few seconds then all I get is ding, ding, ding, I have to use task manager to close the browser. I need to know where to download that previous version of Firefox so that I can get to my email.
