Hi, Please [http://kb.mozillazine.org/Locking_preferences see this.] The settings you may want to lock are '''network.proxy.http''' and '''network.proxy.http_port''' or '''network.proxy.autoconfig_url''' ...............................................................................................................................

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift

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

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: * http://kb.mozillazine.org/Locking_preferences 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

Got it! Thanks for all your help!!!
