Rated 5 out of 5 stars

The addon itself if great. Very useful and lots of options. However, why was this not included in the new TB3? I mean, Personas got included in FF3.6 and it's not even useful. It may say 3.0.1 compatible but I still had to re-install it after TB updated. Please make Lightning an official part of Thunderbird.

This review is for a previous version of the add-on (1.0b1).
