Hello, I have Win 10 and FF, both newest version. When I view a Youtube-Video in theatre mode, then close FF, open FF again with a video, this video does not show in theatre mode. Cookies are allowed. Any solution to open the videos ALWAYS in theatre mode (not fullscreen)? Thanks for help.

This is not a browser issue. Even Chrome won't reopen the video in Theater Mode.
