I am getting the XULRunner error. I did a "clean install" of the latest version and am still getting the following error: >XULRunner >Error: Platform version '11.0' is not compatible with >minVersion >= 12.0 >maxVersion <= 12.0

What do I do now?

If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox. Other security software may have similar features to prevent Firefox from updating files properly.
