It's a great addon!!
One addon for ALL email accounts!!
1. if the user wants,
the notification showing the number of unread emails
to show the new spam emails too
(ie. to show eg.1+2 ----> 1 new mail & 2 new spam emails).
In this way, you won't miss any emails that may have accidentally labeled as spam in your email account.
2. to make a way to open ALL the mail accounts in tabs simultaneously
(eg. by pressing Ctrl+click on the statusbar icon of Webmaill Notifier)
