Hi cosbygerald,

Thanks for the report!

1. Can this problem be reproduced with other versions? Or it only happens with Firefox 76?
   • ESR: https://www.mozilla.org/en-US/firefox/enterprise/
   • other versions: https://www.mozilla.org/en-US/firefox/channel/desktop/
2. Does this only happen on youtube? Do all other sites work well?
3. Can this still be reproduced if you switch the user-agent?
   • Switch user-agent from Firefox to Chome would make the website think you are using Chrome browser.
   • There are some add-ons (e.g. user-agent-string-switcher) that can switch the user-agent

S1 or S2 bugs need an assignee - could you find someone for this bug?

Update: I completely scrubbed Firefox, including all library items, from my system and re-installed Firefox. That appears to have resolved the problem!

I will resolve this then. Please reopen if the issue reoccurs.
