Waardering 4 van 5 sterren

Works as advertised, thank you! However, the permissions asked are frightening (full access to Thunderbird and to the computer). As Comunica2 mentioned, one can disable the plugin when not used as a workaround.

Deze beoordeling betreft een eerdere versie van de 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.
