Problem with firefox : youtube player is not resized.

Please fix it , Thanks

I tested it with Firefox 116.0 (64-bit) and Violentmonkey v2.15.0 and it appears to be working.

What is your specific setup that you are using?

The setup that I am using is like your third picture.
Can you test it to make sure you don't have conflicting CSS styles or extensions?
