Facebook video

Posted

Videos in Facebook show black. My drivers are up to date. The same videos play on my laptop, but not on my desktop. All software on both computers are the same, Windows 7. When I chose "restart Firefox with add-ons disabled" it works, however I already disabled all add-ons, so I cannot pinpoint on an add-on as the source of the problem. The videos play with Chrome and IE, but not with Pale Moon. It plays in Pale Moon when restarted in safe mode.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

It defitinitely was the Hardware Acceleration. I have tried several options with Hardware Acceleration enabled, but only disabling it proved to work. Thanks for your speedy response.
