YouTube won't go full screen

more options

You Tube will not go full screen. I've tried reinstalling, clearing cache, refreshing page, pressing F11. Nothing works. It will go full screen in a private browser, but not in a normal one.

I wonder whether this a problem with the F11 key being blocked/intercepted by the site or an add-on. Could you test whether the full screen button on the menu works -- it is the last one on the Zoom row.

I don't think F11 or Firefox's built-in full screen is relevant, so please ignore that. The display in your screenshot is somewhat similar to when you scroll down, but presumably you didn't scroll down. Does scrolling up/down/up make any difference?

There are a couple new threads on r/Firefox about this, too:

Users there reported that if they are signed out or using a private window (where, presumably, they didn't sign in to their accounts), then the problem doesn't occur.

Maybe Google made a change?
