Using Firefox 77.0.1 64 bit on Win7 Pro. Picture-in-picture is disabled in Firefox settings; but every video window from, for instance; www.nbcnews.com; not only starts playing automatically; but as I scroll down, the picture-in-picture floating window appears. I do NOT want these videos to play automatically and I do NOT want picture-in-picture... forced on me from a website. How can I stop both picture-in-picture and autoplay? Thanks for your assistance!
