Rated 5 out of 5 stars

I noticed that you added Thunderbird support in the final release of 1.1.2! Thanks! I now have your extension installed in both Firefox and Thunderbird. I'm happy that it works great with my themes (as mentioned here on your AMO page)! Kudos to a great add-on!

This review is for a previous version of the add-on (1.1.2). 

Thanks L.A.R. Grizzly.

I guess I have something for you. Check the latest devbuild. ;-)
