How to lockdown and prevent add-ons from being installed?
Hi. I'd like to lockdown an installation of Firefox on a Win XP computer, to prevent add-ons from being installed by limited account users. How do I accomplish this please?

I wasnt too sure a limited user account could install add-ons in XP pro. You certainly have the ability as an admin to lock or change permissions on any folder and file you wish on a limited user account.
My XP pro system is mothballed, so can not experiment at the moment.
Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify default values.
Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); // use this to disable the byte-shift
See:
You can use these functions in mozilla.cfg:
defaultPref(); // set new default value pref(); // set pref, but allow changes in current session lockPref(); // lock pref, disallow changes
lockPref("xpinstall.enabled", false);
