body: <p>Is it possible to determine if Google Chrome is in incognito mode via a script?</p>
  
  <p><strong>Edit:</strong> <em>I actually meant is it possible via user-script, but the answers assume JavaScript is running on a web page. I've re-asked the question <a href="https://stackoverflow.com/questions/2916876/is-it-possible-to-determine-if-chrome-is-in-incognito-mode-via-user-script">here</a> in regards to user scripts.</em> </p>
