title: ipython notebook firefox scrollbar
body: <p>I have a pandas DataFrame with more than 70 columns.<br>
  When I produce a calculation on it, firefox (on windows) has the DataFrame printed in a greater space than the window is allotted for it. I would like the scrollbar to fit inside the ipython window allotted for it. Is there any clean way to handle this? </p>
  
  <p>It can be recreated in firefox using this code in an ipython notebook window.</p>
  
  <pre><code>df = pd.DataFrame(np.random.randn(100, 20))
  df.tail()
  </code></pre>
