I just got a new laptop it won't let me full screen a video that I am watching. What should I try?

I am using a site called couchtuner and when I am using Firefox and I press the full screen button and nothing happens. The video keeps playing it just doesn't go full screen. I have gone on youtube but those videos go full screen just fine. It also goes full screen if I use microsoft edge.

The video code on the site may not have Full-screen support have you tested this using a different browser?

It works fine on a different browser, just not Firefox

It is possible that the video is played in an iframe and that the outermost iframe is missing the allowfullscreen=true attribute that Firefox needs.

This can happen if there are multiple iframes nested and only the iframe with the video has this attribute. You can possibly check this in the Inspector via the right-click context menu.

Can you give a link directly to a page where this problem occurs, assuming no login is needed?
