Rated 3 out of 5 stars

Does what it promises. I give 3 stars because it is not really useful to me. If it were minimizing to TRAY, I would give 5 stars. I need to keep Thunderbird running because of calendar alarms. What's the use of a calendar if it's not running?

This review is for a previous version of the add-on (2.0.1.2).
