Good add-on but unfortunately not working Rated 4 out of 5 stars

Good add-on!! I continuously use this add-on forever, if any major problem.
Buy the way, I update the thunderbird 5 from 3 and also this add-on. But the column by this add-on shows just blank. I have been using nickname of address.

This review is for a previous version of the add-on (0.5).
