Hello!
I'd like to add a border to the Picture-in-Picture window; so I've added the following code to my userChrome.css file:
html[windowtype="Toolkit:PictureInPicture"] { border: 2px solid red !important; }
But the border doesn't appear at the bottom; only on the left/top/right sides. How could I fix this?
If I set the border to more than 2px, then I can see it; but if I hover over the PiP window, the shadow of the control buttons cover the borders; is there also a way to change that shadow (without removing it) so that it doesn't cover the borders?
Thank you very much for any help!
