This would be one advantage of the system's built-in PiP mode employed by Safari. I don't find the limitations (maximum size, single video) to be hinderances.

Can't you trigger that in Firefox also by right clicking on a video (or twice on YouTube) and then choosing PiP?

Problem is Firefox PiP don’t move other desktops on macOS. It is only available at where your window is.

I wish Safari could just open the video in a normal QuickTime Player window instead of a QuickLook-esque thing...
