New laptop startup. Installed Firefox (has edge) and now in Firefox it will not play videos. Tried Youtube and just get a spinning wheel. Tried videos on other websites and get the same issue. Edge was doing that also and I had to change a setting in Edge. I tried that on Firefox following a web search for "videos won't play using Firefox" but have had no success.

If you have Windows 10 N or KN then you may not have the Media Feature Pack installed. https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows
