Rated 5 out of 5 stars

It doesn't work in TB 102.4.2 (64 Bit).
Sorry but there is no entry in the "Tools" menu of Thunderbird underneath the hamburger menu.

*****************************

Correction:

I have to correct myself: I finally found it in the "tools-menu". Not underneath the "hamburger menu" but above in the menu bar. So it works and everything seems to be OK! - sorry for the inconvenience

This review is for a previous version of the add-on (2.2.6). 

That's strange. See https://photos.app.goo.gl/Yaq6naxVYHpaWaqs7
