How do I get you Tube videos to play in Firefox? All I get is a black screen.

You Tube will not play videos. Flash videos already on my PC play, they just do not do so when I log on to You Tube.

I installed Flash version 10 and videos played on You Tube's site, but would not do so on my PC.

I installed Flash player 11 with the bug fix, and now they will not play on You Tube but they do on my PC.

You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3.


Try to disable hardware acceleration in Firefox.


Try to "disable the hardware acceleration" in the Flash Player.

That certinly worked for me. It seems that the problem lies with #Real Player, when I got You Tube videos playing again, all my .flv videos on my PC would not play. I chose another programme to open them with and now everything is fine.

I think it is totally ridiculous. I shouldn't have to jump through all kind of hoops to use FireFox. FireFox needs to jump through all the hoops first and fix their problems. Let me know when you get it all fixed. In the meantime...I'll just go back to using IE. At least it works!
