Firefox cannot play some html5 youtube videos.
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
