Hello and thank you for your report, 

There is nothing that can be done on our side since the problem is from the site and not how FF handles it, please contact the site owner and inform him about this specific problem.

Closing the issue.

I had a look at this as well, and agree with Bogdan. To elaborate, the reason this is a site issue and not a Firefox issue, is that the site is not using the Fullscreen API to make the video fullscreen. Rather, they are doing something custom. You can tell this because the video controls look different from the built-in ones, and the behaviour is very different (no auto-rotation, popup announcing fullscreen mode does not appear, URL bar does not hide, etc.).

Note that the page cannot just hide the URL bar without using a special API like Fullscreen. (This is a security measure. Otherwise, a malicious page could potentially hide the URL bar, draw its own, and hijack your browsing.)
