Rated 4 out of 5 stars
Nice add-on for Thunderbird 3.1.9 only one problem.
Wen you compose a new mail with a adress boek in the side bar left...than you don't see the kolobok smiles side bar ALSO in left sidebar. (a conflict)
Maybe it is an option to choose wether you want it left or right. Left is better when you use the adress boek!
