Only recently have i started to get this error message on youtube videos
"Your browser does not currently recognize any of the video formats available."
Its not all of them but most of them give that to me, its quite annoying that i have to load up chrome just to watch a youtube video.
I'm using FF19.0

I was having the same problem but I kinda solved it. Go to and opt out of the HTML5 trial. Now videos should work in YouTube without any problems.
