I don't see how installing Firefox could have stopped the DWM. That's really not something we do - not the installer, and not Firefox itself. I expect there is some other issue at play here. Try following the steps here:

http://support.microsoft.com/kb/976170

and/or asking Microsoft for support.

Please reopen this issue if you manage to fix the issue, and reinstalling Firefox brings it back.
