Help! After this morning's update installed, an error message appeared that read: "XUL Runner. Platform version '6.0.2 is not compatible with miniVersion =6.0.1 maxVersion =6.0.1" Now Firefox won't open or respond at all. What's the fix?

Error dialogue box appeared:
XUL Runner. Platform version '6.0.2 is not compatible with miniVersion>=6.0.1
maxVersion<=6.0.1
This happened a few minutes ago when I clicked on the Mozilla icon.

If you use ZoneAlarm Extreme Security then try to disable Virtualization and do a clean reinstall.
