Hi,

Recently, Firefox cannot play some html5 YouTube videos.

For example, Firefox cannot play this: https://www.youtube.com/watch?v=LoeSLQwCmZs

But it can play this: https://www.youtube.com/watch?v=1JqR3GVqib4

I refreshed Firefox, so it has not addons installed and cleared the cache but the problem persists.

The flash player plugin is disabled, but if I enable it, then both videos can be played.

I will greatly appreciate any help.

Here I add the YouTube debug information: {

Does it work with a 32 bit Firefox version?

What does the YouTube test page show (About the HTML5 player)?

You can check the media prefs about:config.

I downloaded the 32 bit version of Firefox 43.0.3 from Mozilla webpage. Then run it, but got the following error: XPCOMGlueLoad error for file /opt/firefox/libxul.so: libfreetype.so.6: cannot open shared object file: No such file or directory Couldn't load XPCOM.

After installing the following packages, I could run and play in the 32 bit Firefox both videos successfully:

  • libfreetype6-32bit
  • fontconfig-32bit
  • libXrender1-32bit
  • libXext6-32bit
  • libXdamage1-32bit
  • libXfixes3-32bit
  • libXcomposite1-32bit
  • libasound2-32bit
  • dbus-1-glib-32bit
  • libgtkglext-x11-1_0-0-32bit
  • libXt6-32bit
  • libgthread-2_0-0-32bit

The problem persists with the openSUSE Firefox.

The test page you suggested give the following diagnosis:

  • HTMLVideoElement: supported
  • H.264: supported
  • WebM VP8: supported
  • Media Source Extensions: supported
  • MSE & H.264: supported
  • MSE & WebM VP9: supported
