Which Firefox tabs are playing video or audio?

PROBLEM: After a restart of Windows 10 and re-starting Firefox, a Firefox window with a YouTube web page in a tab will start playing unbidden. When multiple Firefox windows with multiple tabs each are in use multiple YouTube videos will start playing. (Only one of possibly multiple YouTube tabs per FireFox window, I believe.) The cacaphony is annoying. Tracking down the offending tabs is difficult. (There is no "Show tabs playing media" feature in Firefox.)

QUESTIONS: (1) How do I prevent Firefox from playing media (YouTube and others) unbidden when Firefox re-starts and re-loads its tabs? (2) How do I quickly find which Firefox windows have a tab that is playing media? (3) How do I quickly find which Firefox tabs are playing media? (4) How can YouTube videos be prevented from automatically starting when a Firefox web page with that video is re-loaded?

You can click the "List all tabs" (Tab Manager) button at the far right to see what tab play media and possibly mute them.

I think that easiest to prevent tabs from playing media is to load all tabs on demand, i.e. you need to click a tab and to load this tab. These two prefs in about:config control this feature.
