Youtube loses focus entering fullscreen

Hi there
I have found this issue when trying to watch Youtube videos.
Whenever I enter fullscreen whether by pressing F on the keyboard or double clicking the video, I have to click the video again in order to adjust the volume with the arrow keys.
I have this issue in both Firefox and Edge and it never occurred when I was on Windows 10. I have even tried reinstalling Windows 11 from scratch.
Any ideas?

Thanks

I think they just fixed it in Firefox 110.0.1

Seems to be working now that you said it. Firefox must have updated without me knowing. Still weird how it happened in Edge though as well.
