title: FireFox - Are all preferences in about:config located in .js files?
body: <p>I am writing a script to grab some Firefox settings, however it looks like some preferences are not within Firefox's various .js files. </p>
  
  <p>The preferences I am referring to are the preferences in about:config (such as network.http.max-connections). The .js file I am mainly referring to is prefs.js.</p>
  
  <p>So my question is: Are all preferences shown in about:config hidden in some .js file?</p>
  
  <p>Thanks!
