I think the developer has unfortunately abandoned us :(

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

Ok. I hear all of you, and thanks for sticking with me. I'm not abandoning... and no excuses. I'm going to try and get this thing fired up in Thunderbird 60.4 to start. We'll go from there. Here's hoping.

TB60 support has been submitted awaiting review. Let me know if you have any troubles.
