since some days I have a problem with the flash player plugin in the Firefox browser. On some videos on YouTube I noticed that I get just a green screen. I still can hear the sound. In Internet Explorer and other browsers, however, the same videos (and all others) play well. I don't know what to do. I can't fix this.
I'm not sure if this happens only on YouTube. I didn't had the time to test other flash players on other websites. But since Internet Explorer don't has any problems at all, I don't think its a YouTube problem.
Here is one example: http://www.youtube.com/watch?v=56wwc1xPreU&feature=related
In most cases, either updating to the newest video drivers or disabling hardware acceleration will resolve this bug. In addition, please see this FAQ:
