I am getting an error "This video file cannot be played. (Error Code: 102630)" when trying to play video classroom videos. I tried some different courses and same result. This is latest version of Firefox on Fedora 30. This happened within the last couple of weeks as they seemed to work before. Any thoughts on how to fix?
OK thanks, didn't know Flash was still needed, although it was working previously without Flash. Hopefully that is removed as a requirement in the near future.
