Note that your list of details of the system shows that you have a user.js file in the profile folder to initialize prefs each time you start Firefox.

The user.js file is present than if you or another software has created this file and normally it wouldn't be here.
You can check its contents with a text editor (right click: open with) If you do not create this file yourself.

The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

You can delete a possible user.js file and numbered prefs-# .js files and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.
