Rated 3 out of 5 stars

The plugin parameters are not saved when thunderbird (T91.9.1) is closed, may be because i use a main password to protect my accounts passwords.

This review is for a previous version of the add-on (2021.9.1). 

If you want to report a bug, could you use the issue tracker instead of posting a "review"? Thank you! — in the meanwhile, I'll have a look
