This started a few days ago, I have no idea how it started. Basically very many Youtube videos don't start in Firefox. They work fine in Chrome (although they don't seem to load instantly, takes a while to start). Here's a screenshot: http://i.imgur.com/z5XP0zU.png

What I've tried:

Reinstall Firefox Reinstall Flash Clear cache in both Firefox and Flash New profile in Firefox Change to HTML5 on Youtube (and turn off Flash in plug-ins)

The Youtube HTML5 page (https://www.youtube.com/html5) looks like this http://i.imgur.com/KlOSgOR.png. In Chrome it's all green.

Please help.

I seem to have solved the problem. I had to manually go remove all Java versions I had and install the newest one. I believe the auto-removal of older versions in the applet when you install didn't work, so I had many versions installed at the same time, and I guess Firefox didn't like that.

Basically all I had to do was go to Programs and Features, remove everything Java related and download it again.

To see "more green" you can enable Media Source Extensions support in Firefox by setting this pref to true on the about:config page.

  • media.mediasource.enabled = true

See:

Did you clear the YouTube cookies as well?

You may also have to clear the Flash local storage.

  • Windows Control Panel > Flash Player > Storage: Local Storage Settings
    • Remove a specific domain: Local Storage Settings by site
    • Remove all domains: Delete All and Delete Data

Flash Website Storage Settings panel:

Global Storage Settings Panel:

If I set media.mediasource.enabled = true, Youtube stops working completely if I have enabled html5. There's a never-ending loading screen on the flash player. The other combinations of html5 on and off and this true or false appear to be the same (error).

Yes I have cleared both cookies and cache, browser and flash.
