Rounded YouTube Player (Derounded)

Of course, who am I to give you only half a video? Here's the video with all the corners you could ever want.
Also, it turns out that I'm not the only one who's fed up with this rounded corner nonsense. There exists a browser extension that gives back all that was taken away.
addons.mozilla... This is for Firefox, I don't know if there's one for Chrome, or Edge, or whatever browser you may be using.
There is hope, after all.
