Settings are stored inside the file in the profile folder, may open it form the Troubleshooting Information window, files is prefs.js
each setting written in the line beggining with user_pref(. So open the profile folder and close the browser backup the settings file then, (do buckup while profile folder quite often) delete file, launch the browser - did it affect? yes - close the browser, restore the file, edit it to delete a half lines, launch browser - did it affect? yes - restore the file, divide deleted half for a half and keep on.
