Rated 5 out of 5 stars

In the very last version of Thunderbird (currently in beta) the account list appears to be empty, so it is impossible to exclude accounts you don't want to be notified of.
5 stars for all the rest.

This review is for a previous version of the add-on (0.4.3). 

Solved in version 0.4.4

Rated 4 out of 5 stars

Very good but, as already said, it would be better if
1) the tray icon go away when there are no more unread mails and
2) if we could have only one new mail icon (today I had four in the notification area)
Thanks
