title: ignore firebug console when not installed
body: <p>I use Firebug's console.log() for debugging my website. If I try viewing my website in browsers without Firebug then I get a <strong><em>console is not defined</em></strong> error. 
  Is there a way to gracefully avoid this error?</p>
  
  <p>I found <a href="http://snippets.dzone.com/posts/show/6326" rel="noreferrer">this potential solution</a>, but it seems a bit cumbersome. 
  And ideas? </p>
