I am running firefox 4.0 just upgraded to it, and i tried to access my classes for today but the site doesn't support 4.0 but supports 3.0 and 3.5. I was wondering how i can go back to 3.0 or 3.5 so that i can still access my classes using fire fox. I prefer fire fox over internet explorer.

It would be better to use the portable Firefox version for such websites if you can't use Firefox 3.6.x. Downgrading to an old and no longer supported Firefox 3.0 version is not recommended.
