You get this error message when there is a .js (local-settings.js) file in the "defaults\pref" folder that specifies to process the mozilla.cfg file, but the mozilla.cfg isn't found.
Did you make sure that the mozilla.cfg doesn't have a hidden .txt file extension?
You can use the mozilla.cfg file in the Firefox program folder to set or lock preferences and run privileged JavaScript code.
A local-settings.js file needs to be placed 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
The mozilla.cfg file needs to start with a comment line (//).
