I use win7 64bit, I use zonealarm firewall and avast antivirus, Ive had no problems with firefox 3.6.? but when installing firefox 4 everythings ok until it tries to check the capability of previously installed pluggins and at this point freezes!!! Ive got 3 previous pluggins: zonealarm toolbar and a couple of others I think. Ive had to go back to using firefox 3.6

Reproducible: Always

Steps to Reproduce:
1.installing firefox 4 everythings ok until it tries to check the capability of previously installed pluggins and at this point freezes!!!
2.ctrl alt del, shut down not responding firefox program in task manager, restart computer, uninstall firefox 4, restart computer, repeat step 1...
3.repeat step 2 and then step 1....

Actual Results:  
freezes/crashes at same point every time. so gave up and went back to firefox 3.6

Expected Results:  
should have completed installing firefox 4

People seem to be saying that firefox 4 doesnt work with win 7 64bit and as from my experience they are right. is it true?

That is actually Firefox (hence why you killed firefox.exe) and not the installer.
