Rated 5 out of 5 stars

Excellent add-on. I use thunderbird on my PC and Gmail Manager on my laptops. This is perhaps the most useful add-on yet for email. Might have to make a contribution on this one. now if they could include yahoo, aol, and windows live accounts that would be the ultimate.

This review is for a previous version of the add-on (0.5.7.5).
