I have an issue with a certain video on Mozilla
So basically my YouTube video screen is large and shrunk only for this video, see pictures, so as you can see I get an HTML5 error and then if I go to full screen that happens, I currently have YouTube Flash Video Player since I prefer Flash, and the other videos are normal, help please.
The url would be helpful, and the warning could be that firefox does not have a 3d viewing codec?
The codec for this video player for example is https://www.youtube.com/watch?v=kLRswHMbwHU
Try Firefox beta version 40, it displays for me.

Try to uninstall the older version of Flash as well.
