I have two Ubuntu 12.04 Desktops with Ncomputing vSpace software configured for remote terminal users of Ncomputing L300 thin clients. Both these desktops have Squid configured and connected to internet. So in a way users logging in to these machines can directly access internet without squid. Now users can remove the proxy and have unrestricted access anytime. Which is the reason I want to enforce proxy on users settings which they cannot change. I am fine if the settings makes it mandatory for root or sudo user of Ubuntu. Is this possible ?

Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.

Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg. 

pref("general.config.filename", "mozilla.cfg");

These functions can be used in the mozilla.cfg file: 

defaultPref();	// set new default value
pref();		// set pref, but allow changes in current session
lockPref();	// lock pref, disallow changes
