Rated 4 out of 5 stars

half the add-ons work, half (including yours) don't work. How tired of this fucking program! There are many letters, but I would have passed it long ago.

This review is for a previous version of the add-on (3.1).  This user has a previous review of this add-on.

Well, the new addons are build using the new Web-extension API so this is most probably related to the crashing extension process. I don't think the old addons are using that (but they will stop working in the future probably in the next major release in September).

Anyway, if restarting PC doesn't help and reinstalling addons doesn't help either (make sure to restart Thunerbird after uninstalling), then I'm out of ideas.
You can try to install Thunderbird Beta but it will use a new profile so you would have to setup everything again.

I hate this random issues after updates... it's just frustrating because it should fix issues, not introduce new one...
