Worked once I realized I needed to select both sections of the menu to block the site I was on when enabling this extension. No more forced videos while scrolling through the news site. Video placeholders still pop up but at least the annoying noisy videos do not load nor play.

Blocks annoying pop up videos that move to the corner of your screen and start playing. Finally able to get rid of them on a particular site that I frequent. Love it!!!!!!!!!!!!!!!!
