Rated 4 out of 5 stars

It adds the "new look" to this old Bird :) It's VERY useful!!
Still, since i installed it, Thunderbird it's shown on a maximized window and i can't change it :/
I'm using Ubuntu 10.04 LTS with Thunderbird 6.0.2 :)

This review is for a previous version of the add-on (2.1.1).
