I wish it worked by using the regular web fullscreen API to pop out. Instead of going fullscreen it would just spawn a chromeless window that I can position anywhere I want and control using my regular window manager controls. As an advantage this would give sites full control over the content including having the full video (or other content) controls instead of just play which is what Firefox PiP gives you.
I disagree with that. The browser already does too much "window management" already. I like that it pops out a separate window that I can do with what I please rather than being limited to whatever window management functionality they decide to add to their internal "window".
Possibly - but in my case the windows was just floating on top of all of my other windows, and whilst I could move and resize it, I could not move it like other windows.
So popping out a new firefox window that operates like a normal window would be great, but the current solution seems like the worst of both worlds.
Also on an unrelated note, seeing your username we used to work together - hope all is going well :)
Do you happen to use sway? (Or maybe just Wayland in general does it..)
I'm using a tiled window manager on X and was rather confused by other comments here, before realizing my window manager must be giving me unintended control over the video popup. I just get a floating window that's fully draggable and resizable identically to other windows.
I'm using Gnome actually. I have found that Wayland tends to keep some apps in check so maybe the less options that Wayland provides to clients is helping me here.
