I was wondering if its possible to to set up a computer where a user can only use the web browser and nothing else? they won't have access to any other part of the computer and they won't be able to see any other part of the computer. I was wondering if its possible to setup a computer (windows, mac, linux) and have everything else blocked and locked so that only the web browser (preferably firefox) is available. the user won't be able to minimize or close the browser and documents or files that come off the web are viewed in the browser and deleted once the user is done viewing the documents or files. The user won't be about to connect any devices like a usb, ipod, etc... This probably sounds like a stupid question, but I know it can be done and I know its been done but I just don't know how its done. What addons or plugins will I need? Will there be any scripting or programming involved?
