title: How can I change Chrome settings to test using navigator.language
body: <p>I'm trying to internationalize an app and need to test how it behaves in other locales.</p>
  
  <p>However, <code>navigator.language</code> always returns <code>en-US</code>, even if I change language settings in both Chrome and OS X.</p>
  
  <p>What can I do to the browser to force <code>navigator.language</code> to return something like <code>es-MX</code>?</p>
  
  <p><strong>Clarification</strong></p>
  
  <p>I'm trying to make the change as a user, through the GUI, not with code. </p>
