Update doesn't work Rated 1 out of 5 stars

Was a great add on and i loved it and it worked flawlessly for years. installed the update version 1.0.1, don't get the error message anymore, but don't get the message notification either. It just says no mail regardless if there is mail or not. very annoying. I am using FF 6.0.2.

This review is for a previous version of the add-on (1.0.0.21).
