I am trying to help someone with a Win XP computer. They are trying to set it up for basic internet/skype functionality but also wants parental controls in place. She uses FireFox and from my preliminary research there appears to be no built in parental control options. It looks like there are quite a few extensions available to accomplish this but i think the extensions can be easily removed/disabled by any user (without Administrator control). I was wondering what steps i could take on XP to require the Admin's approval to remove/disable extensions in FF or to uninstall FF or other applications. Also i want it to require the admin's PW if someone wants to install any applications. Does XP offer anything for this?
