Is there a way to restrict the access to plugins and addons to the administrator? We do not want our patrons to have access to the ability to modify Firefox in any way.

You can consider to lock plugin.state.* prefs for each plugin to a specific value.

  • 0:Never Activate; 1:Ask to Activate; 2:Always Activate

You can 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");
pref("general.config.obscure_value", 0);

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

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