It's not working anymore on youtube. I use firefox. It used to work just fine but in the last few days whenever I try to watch a video on youtube the ad starts and by the end of the ad it freezes before beginning the second ad. I click play and by the end of the second ad it freezes again before the actual video begins. I noticed the icon somehow turns gray in a few videos as if youtube disconnected it but in most videos the icon is normal and even then the ads play as if I didn't have the extension. Also, when the video finally begins, the console with the buttons (play, sound, full screen etc) takes about 10 seconds to show up.
