title: Is there a good guide to interpreting the Firebug net panel?
body: <p>I’m using the Net panel in Firebug to evaluate the performance of web pages I’m writing.</p>
  
  <p>Specifically, I’m wondering what the precise meaning is of the stages for each resource that’s downloaded (i.e. DNS lookup, Connecting, Blocking, Sending, Waiting, receiving).</p>
  
  <p>But more generally, is there a Firebug guide where I can look this stuff up?</p>
