I've set up Firefox on Ubuntu to run in kiosk (full-screen) mode. This means the user can visit only the predefined URLs. That works fine.
Now I want to set up a second machine the same way, but I cannot remember how I set up the first one. Since I cannot access the menu or the address field, there's no easy way to lookup up the configuration.
Any ideas on how to get the first machine back to normal mode or to find out the Firefox extension or configuration option used?
