Unable to go fullscreen on videos

So, I’ve been having a problem with my Firefox recently. Out of the blue, it decided that it wasn’t going to let me watch fullscreen videos. YouTube Disney+, you name it. Everytime I try to enter fullscreen on YouTube, it’ll try to, the screen will be just black and it’ll exit itself out of fullscreen and tell me “Fullscreen is Unavailable.” I’m not sure how this is happening.

Add-Ons on my browser:

-uBlock

What I’ve tried to do to resolve this problem, to no avail:

-I tried clearing cookies and cache of each website. No success.

-I tried reinstalling the browser completely. No success there.

-I went to about:config and made sure the fullscreen api’s were enabled. They were enabled as they should be.

-Checked website permissions.

What exactly is going on? I’m a little lost here. If it helps, I’m using the latest version of Firefox on MacOS.
