Thats a pitty.. I now deactivated the addon and switched to "MinimizeToTray revived" but unfortunately it does not simply minimize TB as this addon did, but lays it to the tray.

I was looking for a solution to speed up the start of firefox and thunderbird, which lasted always about 3 seconds - time is everything. With this addon, they are starting immediately. Thanks! Concerning firefox: An option would be nice, to close all tabs when minimized and only home tab is displayed when reopened.
