I have tried every suggestion for blocking videos from autoplaying. I have tried Firefox's suggestions, and everything I found on the web, and nothing works. Autoplay happens every time on Fox. Why can't Mozilla get me a straight answer. I cannot be the only person in the world using Firefox, latest version, who has this problem. And, by the way, the way it seems to work is if you leave the video screen visible it does not Autoplay, but as soon as you scroll down to read the article, and thus the video image scrolls up and off the screen, then it starts to play. This isn't just some fluke and I suspect there is some code in the page HTML that does this. So, how the hell do I get it to stop?
