After the last update a few days ago, I have had to go into privacy and security and reset everything, plus go into about:config and reset media.autoplay also. Still, even if the main video on a page is blocked, the little floating video remains and the sliding and floating ads and such still remain. I really need a fix for this. I do research online for a living, and having to close all these annoyances all the time is costing me time, thus money.

How do I now stop all this? Even on this page, an annoying drop-over is annoying me. Time is money, and every second counts in my work. Any help would be appreciated. TIA
