you guys should try to do this and revive GPUM. Another abandoned extension that is much much much better than Gmail Manager.
Rated 2 out of 5 stars
Has the potential to be the best Gmail extension for Firefox.
Unfortunately it's very Buggy, some essential functions like "Mark as read" doesn't work anymore for a long time and it has not been fixed. I wish the developer would give it a little bit more attention and updates.
