I think 19 or 20 it freezes firefox so u have to crash it And if u upgrade from 18 or 19 to 20 something like that it causes problems launching firefox after a crash, which is weird because even tho the task manager shows no firefox running or anything related, it's as if session manager is still on somehow but hidden, because not even crashing explorer causes the prob to go away, u have to reinstall again or restart ur computer.

This review is for a previous version of the add-on (0.8.0.8.1-signed).
