facebook videos not playing in firefox. IE plays them fine, also no problem with youtube videos in firefox.

Facebook videos are not playing in firefox, it plays youtube videos fine. The fb videos start to load and after that just a black screen remains.

No such issues in IE, I've no addons installed, flash player is latest, and tried by enabling/disabling the block popups option.

Thanks in advance.

go to Help Menu -> select "Restart with Add-ons Disabled"

Firefox will close then it will open up with just basic Firefox. You can enable the Add-ons later. Check and tell if its working.

Check if clearing the Cache helps:

  1. Go to Tools menu > Options > Advanced > Network.
  2. Under the Offline Storage section, click on the Clear Now button.

Otherwise, see the possible solutions in this article: Fix common audio and video issues.

Thanks @dynamite and @mha007, but the problem still remains.

There were no conflicting plugins, vlc or any dlls.

You can try to disable the hardware acceleration in the Flash Player. See Flash videos won't play full screen

Flash "Display settings" window:


Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

Update the Flash plugin to the latest version.
