This is a bookmarklet, not an extension, so you only activate it when you need it. To answer your actual question: autoplay videos that follow you when you scroll >:|

uBlock origin allows me to select elements and add them to a universal blacklist. Slowly but surely I am defeating all news websites auto-play videos.

Firefox has an about:config setting that kills them all.

Kind of random comment, but thank you! I switched to Firefox from Chrome a few weeks ago, and one of my major annoyances was that Firefox would play Youtube videos opened in background tabs, even before the tab ever got focus. Seeing your comment gave me the idea to search about:config for a setting related to autoplay, and I found a setting that enables my preferred behavior.

So, thanks!
