Firefox isnt working

[Musafir]

I have windows Xp SP2 and have two user accounts in my computer one is limited and the other is Administrator both have latest Firefox (2.0.09) installed. I installed some Add Ons/extensions on firefox running on Adminitrator user account and now it has crashed. Its not starting anymore and whenever I click on its icon it keep crashing saying "firefox.exe has encountered a problem and needs to close. We are sorry for the inconvenience." I have tried fixing in safe mode but the same message error shows up everytime.

I have also uninstalled and installed again but the same problem persists. Its working fine on my limited account though. I would appreciate any help.

Thanks in advance

The profile account on your admin side is corrupt. You need to make a new one. You can see the instructions here

Don't worry it isn't as hard as it looks. Only takes about 3 minutes.
