Rated 3 out of 5 stars
It seems to have some problems. yesterday was working just fine. Today, not have done any upgrade on FF, it is not working. Must be more reliable. Although still being a great addon.This review is for a previous version of the add-on (0.9.2.1-signed).
There were some errors that I found while installed firefox 6, please update to version 0.9.3
