works fine the most time, but not always

I usually love this ext, but the past few days, it's been acting up... since the recent FF update. It starts off working properly, but then everything freezes on my computer, I can't even move my mouse. Had to hard reboot the last time I used it. Please fix. thank you

cette application est tres pratique

It was not working because of the last firefox update. You should uninstall the add on and CLOSE the firefox before install it again. It's fixed now.
