Firefox straight up not playing streaming content
As the title says - no Podcasts, YouTube, or embedded videos. It's possible it may be an add-on issue, but given that the issue is so completely comprehensive, likely not.
Yeah, I was in Win 10 on Youtube yesterday and something has been going on with YT and Firefox for awhile. My daily driver is Linux and have no issue on YT.
Can you provide screenshots and links to pages that are not working for you? Have you tried in safe or private mode. I do recall trying in safe mode, but one side of the site was showing logged in, but the other side was showing the sign in button.
