When Firefox first released this feature it was amazing, but after a few updates, it seems that when I enable picture in picture, the video window pops up, but does not remain on top of other windows. Is there a way to revert this behavior to keeping the video on top of other windows, including the browser?
I don’t think so. Just don’t minimize the Firefox window and it will stay on top. At least, that is what I do.
For mine, it falls behind Firefox the moment I click on anything else, even the current page on Firefox
