When I try to play a youtube video, It shows a black screen for couple of seconds (no buffering icon either!) and then suddenly the progress bar just jumps to the end as if it has finished playing the video. This happens for some youtube videos but the same videos can be watched in IE without any issues. I tried clearing the cookies and history, but didn't work. I am on the latest adobe flash. Is there any way to fix this? Below is a youtube video that I am trying to play but firefox doesn't wanna play it! https://www.youtube.com/watch?v=mEH6tDLKcVU Firefox: 24.0 Flash player version: 11.8.800.168
