flash player not working under xvfb

Flash player not working in firefox (centos 5.5 x64) that run with selenium under XVFB. I开发者_运维问答'm getting just black screen in place where flash should be visible.

Tried both 32 and 64 versions.

May you suggest anything?

If you are running this from a terminal, make sure you installed the correct Flash player plugin and not Flash itself. If you were using Ubuntu, you would run this command:

sudo apt-get install flashplugin-nonfree

Also, what version of Firefox are you running? If you are running 3.0, make sure to open defaults/preferences/firefox.js and make sure you don't have anything here that would be stopping Flash.
