I have 3 Gmail accounts which I have tried to enter into the so-called GMail Manager, but the Add-on can't seem to remember any of them!!
The support site is blank! The Mozilla forum has lots of similar reports of this not working. This seems to be an abandoned Add-On!!!
I don't understand why Mozilla lists this as TOP RATED!!!
