Seems like this add-on has been abandoned. Not compatible with Thunderbird 7. Love the website, wish they would update their add-ons.
The extension has been updated so it can be installed on Thunderbird 7.

Great program. I really like the map, it makes mailing packages with tracking number really fun.This review is for a previous version of the add-on (1.0.4e).
