Very dubious. I won't install it until this is fixed.

This review is for a previous version of the add-on (2.1.1).

I think many other add-ons are the same.
Add-ons published on addons.thunderbird.net (ATN) have passed human review.
In addition, the source code of this add-on is open, and anyone can check it.
