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

Helpful replies

I was having the same problem but I kinda solved it. Go to http://www.youtube.com/html5 and opt out of the HTML5 trial. Now videos should work in YouTube without any problems.

YouTube HTML5 Video Player

This is an opt-in trial of HTML5 video on YouTube. If you are using a supported browser, you can choose to use the HTML5 player instead of the Flash player for most videos.
Your comments will help us improve and perfect the mixtures we're working on. So jump in, play around and send your feedback directly to the brains behind the scenes.

What does my browser support?

Video tag
h.264
WebM

You are not currently in the HTML5 trial.

Supported Browsers

We support browsers that support both the video tag in HTML5 and either the h.264 video codec or the WebM format (with VP8 codec). These include:

Firefox 4 (WebM, available here)
Google Chrome (WebM, available here)
Opera 10.6+ (WebM, available here)
Apple Safari (h.264, version 4+)
Microsoft Internet Explorer 9 (h.264, available here, WebM support available here)
Microsoft Internet Explorer 6, 7 or 8 with Google Chrome Frame installed (available here)

Notes

Fullscreen support is partially implemented. Pressing the fullscreen button will expand the player to fill your browser. If your browser supports a fullscreen option, you can then use that to truly fill the screen.
If you want to find videos with WebM formats available, you can use the Advanced Search options to look for them (or just add &webm=1 to any search URL).

Additional Restrictions (we are working on these!)

Some videos with ads are not yet supported (they will play in the Flash player)
On Firefox and Opera, only videos with WebM transcodes will play in HTML5
If you've opted in to other testtube experiments, you may not get the HTML5 player (Feather is supported, though)
