title: How does FireFox work? Source code walk through?
body: <p>I'd like to learn how FireFox works behind the scenes. I'd like to understand the source code and the different components but the code-base is rather large and I'm not sure where to start. </p>
  
  <p>I'm wondering if there is some sort of walk though written up by anybody either from the firefox team or from outside the community. </p>
  
  <p>I've looked a little bit at: <a href="https://developer.mozilla.org/En" rel="noreferrer">https://developer.mozilla.org/En</a>  but I don't see anything that screams "Start here". I'm simply trying to review their code base for [self-]educational reasons.</p>
