Review for Gmail Manager by beltman713
Rated 5 out of 5 stars
I've been using this add-on since Firefox 1.x. It is simply the best Gmail checker out there. I tried some of the others, but this one was the only one that would check multiple Gmail accounts. Gmail Manager has never let me down.
This review is for a previous version of the add-on (0.5.5).To create your own collections, you must have a Mozilla Add-ons account.
