Rated 3 out of 5 stars

Mine isn't working. In the Add-ons menu, it says: "Requires additional items". That's all. I have Lightning installed. TBird is version 2.0.0.21.
My only add-ons are enigmail and lightning. Anyone have a clue what "additional item" it wants?

This review is for a previous version of the add-on (0.5.1).
