Rated 5 out of 5 stars

Very convenient add-on to export whole folders to mbox. No need for those fancy, expensive apps you can find online as the add-on is very intuitive to use.

This review is for a previous version of the add-on (12.0.4).

Thanks for the very nice review!
If you are interested I am really needing beta users for the new v14 to support Thunderbird 115.

It has a new mbox implementation.
