How can I get Firefox to recognize YouTube?
When I try to play anything on YouTube I get the Firefox doesn't recognizemessage
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:72.0) Gecko/20100101 Firefox/72.0
Hi circemae1, the player might be saying that it doesn't have any formats that Firefox knows how to play. I think that is very unusual on MacOS X systems.
Did this problem just start recently?
Could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.
If Firefox is not running: Hold down the option/alt key when starting Firefox. (On Windows, hold down the Shift key instead of the option/alt key.)
If Firefox is running: You can restart Firefox in Safe Mode using either:
- (menu bar) Help menu > Restart with Add-ons Disabled
- "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Any specific media related messages in the Web Console ?
- "3-bar" menu button or Tools -> Web Developer
