I cant figure this out. I've un-installed firefox and re-installed it a few times, along with flash player, and its not working. I watch youtube videos all the time. When I click on a video, the screen will be white, but audio will play. Sometimes when I reload the page, it will be a black screen like normal, and play the video with audio.

Is there a fix for this?

I have Ubuntu Linux 8.04 LTS Desktop edition.

Yes I have tried installing/re-installing, un-installing Ubuntu restricted extras. No Luck.

THANKS!!!!!!

How are you installing flash? The flash plugin from the Ubuntu repos should work fine. If you are using the flash plugin from adobe then remove that and install the flash from the Ubuntu repos.

If that don't work then create a new profile. Move your ~/.mozilla folder to ~/.mozilla.bak and relaunch firefox.

If that don't work then uninstall the flash plugin from the Ubuntu repos. Then download the linux .tar.gz flash installer from adobe.com:
http://get.adobe.com/flashplayer/
Then untar it (use the exact name of the file here):
Then copy the libflashplayer.so from the directory that is created to /usr/lib/mozilla/plugins:
The restart firefox.
