youtubevideo not playing when login to youtube with Tenfourfox 10
Playing without login in to youtube works fine, as soon as I login to add a video to my playlist it shows the message:
'your browser doesn't support the available video format' refurring to html 5 video.
Got my preferences set to 'Always use private browsing mode'
any idea's?

Just to make sure: When you're logged out of YT, the *same* video plays fine, but it doesn't play when you're logged in?

Yes, indeed. The same video played without being logged in.
The strange think is: most video's on YouTube play fine, it almost seems like a hickup from YouTube itself.
As if not al video's are in html5 format?
Cheers

HTML5 can use different video formats: H.265 and web.m. We support web.m (but not H.264). Most videos are encoded in web.m, so that's not the problem.
If you like, please share a link to one of the problematic videos so I can have a look at it. I tested several videos and they all play fine no matter if I'm logged in or not.
