It stops them from automatically playing in most cases (though there is a bit of an arms race there just like with ad blockers), but it doesn't stop the video container from floating. And some sites start the video when you click to close the floater, then you have to scroll back up to shut up the video, and some interpret scrolling up to video as "oh I want it to float again", so you need to close it a second time.
I don't know if any exist. They are technically possible, but it would just be another arms race because a blocker would need to use names or patterns to detect those floating boxes, but there's infinite different ways they can be named or implemented.

So there is no add-on that specifically focuses on getting rid of this annoyance?
