I have not even used the AddThis 3.1 main features yet, and this app is simply annoying. It uses up screen space but doesn't really need to. If you click on View and uncheck AddThis, the toolbar disappears. However, the next time you start Firefox there is that annoying, space hogging toolbar again. Tried all options to fix this without sucess. I will be uninstalling. Good concept, poor execution.This review is for a previous version of the add-on (3.1.0).
