I hear all this advice about reporting bad ads to the Nexus. OK. ANY add that runs as a video simply chocks my system. I would love to disable Adblock but, I can't. I would allow banner ads, they cause no problem. Video ads totally cripple my system and almost crash Firefox. We can discuss the merits of advertising and how it helps support the Nexus all day long. I agree. I get it. I would love too. Stop the videos and I will disable Adblocker.
