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

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Try to "disable the hardware acceleration" in the Flash Player as a quick test.

i have the same exactly porblem and have screenshot of my own https://support.cdn.mozilla.net/media/uploads/images/2013-01-06-13-19-22-79838b.png

none of the replies did help me please, i really dont like the other browsers and the idea of launching one only to watch a video in youtube freaks me out.

please help me to fix this problem i've tryed E-V-R-E-Y-T-H-I-N-G - reinstall firefox - reinstall and update external patchs/add-ons - cleaning all temporary and chace files - disable firewall and antivirus to see if it sloves the problem - allowing Java & JavaScipt just all the options it demends

none of them helped me... im really desperate

ok guys i think i came up with the solution the problem is with acessing videos on youtube with the normal connection protocol www. or http:// for some reason acessing videos with insecure connection is not allowed by youtube's servers

while https:// which is secured protocol connection is allowed and allow running of videos.

to be honest i dont know why youtube/google not preforming auto-linking between each protocol in cases 1 of them is not working well like facebook's servers do for example.

i will try to contact them and ask them why.

anyway i would like to thank all of you
