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

Information

The local-settings.js file is used by Firefox to reference and load the mozilla.cfg file which contains all the locked preferences.

Rationale:

Loading a custom configuration file is a primary mechanism for setting and enforcing security requirements within Firefox.

Impact:

None.

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');

Default Value:
