The videos do not play except on YouTube. It shows an error message that it can't play the video. I have the latest updated Adobe Flash player. And the same videos work well on IE and GC !

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
