Rated 4 out of 5 stars

Unfortunately I get the double window bug often on Arch Linux on both Thunderbird 31 and 38 Beta. Often times the App Locks Up and I have to manually kill the process. It also seems to me that it would nice to have a "single click / double click" option as single click to maximize from tray seems weird in Gnome 3.16

Nice Work, so far the best Thunderbird Tray for Linux.

This review is for a previous version of the add-on (0.5.6.1-signed).
