title: Python selenium find_element_by_css_selector() not working
body: <pre><code>from selenium import webdriver
  driver = webdriver.Firefox()
  driver.get('http://www.google.com')
  content = driver.find_element_by_css_selector('title')
  print content
  </code></pre>
  
  <p>I can't seem to get any content by any means(tag_name, class_name, name...)
  What is the problem with this code?</p>
