Still the best one!!! Even over Gmail favicon Rated 4 out of 5 stars
This v0.4 Works great in FF4.0.1 in Ubuntu Natty 11.04 Final,
but only updates the status of unread emails if I leave gmail's tab on the Priority/Inbox page.
+1 for bigger number!!!
+1 for allow user to specify a sound file to be played when favicon icon change to unread mail icon.
