title: Chrome: Uncaught TypeError: Cannot read property 'getCurrent' of undefined
body: <p>Whatever I'm doing in chrome, I always see this message in the console.</p>
  
  <p>It's coming from a file called 'popup.js'.</p>
  
  <p>If I click on the name of that file as it shows in the console, I can see that the problem function is chrome.windows.getCurrent</p>
  
  <p>The file in which it is defined attributes authorship to "The Chromium Authors"</p>
  
  <p>What's going on here?</p>
  
  <p>Can I eliminate this error without doing anything that will cause problems when I'm debugging my own javascripts?</p>
