I have been using all the beta releases of Firefox 4, but with the final version I frequently receive the message "Firefox is not working," usually when I have it minimized or am otherwise not actively using it. I did not have this problem before the final release. I am running Windows 7 Home Premium with 4 GB RAM. It does not give me a place to file a crash report. So far I can tell, my Firefox installation and all add-ons u to date and compatible with Firefox 4.

See "Hang at exit":

Create a new profile as a test to check if your current profile is causing the problems. See:

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) See:
