I cannot open Mozilla Firefox. Instead, a XULRunner dialog box appears with the message: Error: Platform version "6.0.2" is not compatible with minVersion >=6.0.1 maxVersion<=6.0.1 edit

Can you please tell me how to solve this problem? I have been running Mozilla Firefox on my Dell laptop with Windows 7 os.

Thanks

If you use ZoneAlarm Extreme Security then try to disable Virtualization.

Do a clean reinstall and delete the Firefox program folder.
