Hi livebuckwheat, Please see: http://kb.mozillazine.org/Locking_preferences for more details.

You can use this content in the mozilla.cfg file:

//
pref("plugin.state.java", 2);

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

I do not see the mozilla.cfg file, where about is it located?

You need to create both files in the Firefox program folder.

• local-settings.js file in the defaults\pref folder where you find channel-prefs.js
• mozilla.cfg in the main Firefox program folder

Thanks. I finally figured that out. You've been an amazing help.
