Below is a the link for a kiosk build of Ubuntu based on 9.10. This build is a specific configuration of Ubuntu that will automatically login as a kiosk user. The kiosk user's xsession consists only of a single Firefox Window.
Be sure to see the FAQ at the bottom.
It has been designed so that the kiosk user can only use this Firefox window. I have taken every measure I could think of to disable the opening of other windows and closing of others. If the Firefox window is closed, the session ends and restarts gdm.
