title: What do the coloured dots in firephp output mean?
body: <p>I've seen green, orange, &amp; grey dots, and they don't seem to correspond to variable types… any ideas?</p>
  
  <p>I didn't find any mention of them in the FAQ, etc: <a href="http://www.firephp.org/Wiki/Reference/FAQ" rel="nofollow noreferrer">http://www.firephp.org/Wiki/Reference/FAQ</a></p>
