how about making an app that stops the stupid player from popping up every time you close it!!

The popout player doesn't show up over other tabs or windows so it's basicly useless.
However i have found that mozila already has an inbuilt popout player called picture-in-picture but it's kinda unintuitive to reach for some reason. You can double right click or shift right click on a youtube video to bypass youtube's fancy right click menu and reach mozila's right click menu. In mozila's menu you will have an option that saies something along the lines of "watch with picture-in-picture", idk exactly how it would be in english cuz my menu is in romanian so i'm having to translate.

doesn't works

Unfortunately doesn't work how i needed it to. the popout appears fine and comes up quickly when activated but it only stays on top of other tabs if i don't click or type anywhere! as soon as i have to click on something else it disappears which means i can't perform other tasks without the video going to the back. basically works exactly the same as if i were to open the video in a new window and will not stay on top of my other tabs while i am typing

Não me serviu de nada. Apenas abre o video em outra janela, mas não fica sobre as outras. O que não tem motivo nenhum.
