Rated 5 out of 5 stars

This one of the best mail notifier I've used. But This extension didn't work properly with Firefox RC2, it was fine till RC1. I'm using V 1.0.0.6. Please fix it ASAP.

This review is for a previous version of the add-on (1.0.0.6). 

I've been using the extension in Firefox 3.0 (both RC1 and RC2) for a few weeks now without any problems. If you have issues please read the Developer Comments below.
