Firefox shows a black box when viewing YouTube videos, though Chrome doesn't.

So I tried to watch a video on YouTube, yet Firefox just shows a black box. Neither the video nor the audio will play. It doesn't crash my browser or bring up any errors, which leads me to believe that it is not a Flash Player problem.

I opened Google Chrome and tried, and it plays YouTube videos with no problems.

I restarted my computer, yet it still does not work.

Any assistance is very much so appreciated.

I just noticed that I can view embedded youtube videos linked from other websites but I cannot view the same videos directly at youtube.com

Does it help if you change the http link to https?

Changing to https fixed it for me. After adding the 'S' it remained for any other video I played.

Thanks.

https works perfectly. But the average Firefox or YouTube user probably won't know this. Hope a real fix is in the works.

I am having the same problem - and the https thing is working for me. Annoying as hell though.

Could your Content > Enable Javascript be turned off? That would make a black square... and check to see if the link still works in Safari or IE.
