Beware! Rated 1 out of 5 stars

One of the worst add-ons I've ever used. It blocked YouTube, giving me a black box that covered the window instead. Only after I disabled this add-on was I able to see and use YouTube again. Didn't work on FF 7, 8, and 9 beta. I'm rating it one star only because the system won't let me give it zero stars!!

This review is for a previous version of the add-on (1.0.7).
