You might want to do a semi-clean or clean uninstall.

Semi-Clean: This will usually fix problems.
Uninstall Firefox - Delete the programs file folder. Navigate to C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\some 8 digit #.
Copy that to another folder -
Delete the profile -
Reinstall
Copy fhe profile back
You will not lose your extensions.

Clean: Same as above but just delete the profile and reinstall extensions.

Hope that helps.
