title: Why am I getting this WebDriver exception in Chrome and not in Firefox
body: <p>Here is the error</p>
  
  <pre><code>WebDriverException: Message: "findElement execution failed;\\n Property \'Error\' of object [object DOMWindow] is not a function"
  </code></pre>
  
  <p>I run:</p>
  
  <pre><code>LoginPage.authenticate(self, self.admin_user) 
  </code></pre>
  
  <p>This works fine, logs me in OK, but as soon as I try to find an element on the next page using the chrome driver:</p>
  
  <pre><code>self.driver.find_element_by_id('Menu_LogInOut')
  </code></pre>
  
  <p>I get the above error.  It doesn't error out in Firefox.</p>
  
  <p>Has anyone else run into this?  What is going on?  How do I get around it?</p>
