1.1 Create local-settings.js file - general.config.obscure

Information

The local-settings.js file is used by Firefox to reference and load the mozilla.cfg file which contains all the locked preferences.
Loading a custom configuration file is a primary mechanism for setting and enforcing security requirements within Firefox.

Solution

Perform the following procedure:

* Navigate to the defaults/pref directory inside the Firefox installation directory and create a file called local-settings.js.

* Include the following lines in local-settings.js:

pref("general.config.obscure_value", 0);
pref("general.config.filename", "mozilla.cfg");
