I think it's obvious that there is something corrupted in this installation. Trying to fix it only prolongs the agony and frustration. I think the OP should wipe, format and reinstall Win 7, then install any missing drivers, followed by Firefox. At that point, he should STOP and evaluate the performance of the system before continuing to install ANY additional software.
A big + 4 here. Then I would make a restore point and update Windows which will make another restore point. If every thing goes well you have a point to return to if needed as you continue.
+5. A clean install will fix 1) any problems with corrupted system files, 2) remove any viruses, and 3) fix any current problems with poorly installed software.
Since it was never answered, what AV do you use?
These tutorials will help make sure what you do is a clean install, will the least likely hood of problems.

Before I tried a full re-install I would check that my video drivers are up to date.
I had an issue with it freezing like you when I first ran Win7. Turned out my video drivers were not current and the card was lacking, so I upgraded.
Might be worth a try.
Also which version of Win7 are you running.. there are differences!
and which version of FF. The original 3.5* had a memory leak that would cause it to hang the system up after a while (on my PC anyway), so I moved to Chrome and have not looked back.
Still use FF (3.6.8 currently) at work, but not at home.
Wow, you guys are awesome. Thank you all. I will have a go at your suggestions tonight and let you know what it is. I think firefox is probably the bandit in this picture. But hey it could be anything. I still don't have 100% faith that I can work with WIN7 in the same manner as I work with XP. This may change with the forthcoming service pack.
oh i use Sophos AV. We get it free from work.
