Check if your Firefox version is supported with selenium server

If you need to run that on jenkins, you need your server to have a display available (X11 server, or xvfb) otherwise no GUI application will be able to run as your server won't know where to display it.

If you have one installed/running, maybe it's only a matter of setting the environment variable DISPLAY to the right x11 display.

There is also the selenium plugin on jenkins that adds the grid to jenkins and then you could configure desktop nodes.

That's your problem. If on linux, use Xvfb. In my case I launch
the RC like this (Ubuntu):

sudo xvfb-run -s"-screen 0 1200x480x8" java -Xmx1536m -jar <standalone jar> -port 4443

With that on 64-bit I can run up to 15 FF's.
