CloseReview for Gmail Manager by Please read this !!
Rated 5 out of 5 stars
Before you critisize : this is the best Gmail account manager on FF. Thing is it WAS, cause it is now not maintained anymore.
But as it is really a nice addon, Erik Nedwidek proposed its fork "Gmail Manager NG" that makes it working for current versions of FF.
