Wow, I'm very impressed. Thunderbird upgraded to 91.1.2 (64-bit) yesterday and this Add-on no longer worked.
Today, I found it had been auto-updated and works again. It is *such* a useful app which allows me to move emails to folders efficiently and quickly.
Yay! I can feel a donation coming on. Thank you.
