You can check if you have a user.js in the Firefox profile folder.

The user.js file appears only if you or another software created, therefore, normally, he wouldn't be here.

The user.js file is read whenever you launch Firefox and initializes the preferences to the value specified in this file, so preferences that cannot be changed temporarily for the current session.

You can check for problems with preferences and rename or delete the file prefs.js and possible numbered prefs-# .js and a user.js file possible to reset all default prefs.
