When I switch videos to fullscreen on YouTube or other platforms, or to switch the browser to full screen, the videos stop. The sound continues. When I click on the video, the screen goes black for a few seconds. Then it works so far again. In Chrome, I do not have the problem

Sounds like a Video Driver issue. I can do Full to standard Youtube with no audio or video losses. And this is W10x64 FCU FF58.0.2x64.

Possibly it is the Beta you are running as shows version 59 here. I would suggest going back to the stable release till the issue is fixed. If you are not reporting these to bugzilla then there is no point in running a Beta or Alpha Release. If you have a bug, file a bug report. https://bugzilla.mozilla.org/ Bug Writing Guidelines : https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines

Please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 58.0.2 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

Thanks for your reply. Now I`m using the version 58.0.2. It seems that this video problem is solved. I still have a problem with that. As soon as I start a game on the side, I get exactly the same mistakes
