Rated 5 out of 5 stars

I love how this add-on works in Thunderbird. Very quick and easy. Unfortunately, it stopped working with Thunderbird 78 with Mac OS Mohave. The window opens but appears open only momentarily. It still works fine with Mac OS Catalina.

Unfortunately, updating my one machine to Catalina is not an option. Of course I understand that you cannot economically support all OS versions, but if you have any ideas for getting it to work with Mohave, please let me know.

This review is for a previous version of the add-on (3.0). 

Please contact me to my support email or create issue on my github:
If possible, add screenshot.
Anyway it really should work independently of OS. As long as you use Thunderbird 78, everything should work fine.
