title: Unsupported command-line flag: --ignore-certificate-errors
body: <p>Using Python 2.7.5, python module selenium (2.41.0) and chromedriver (2.9).</p>
  
  <p>When Chrome starts it displays a message in a yellow popup bar: "You are using an unsupported command-line flag: --ignore-certificate-errors. Stability and security will suffer." This simple example reproduces the problem.</p>
  
  <pre><code>from selenium import webdriver
  browser = webdriver.Chrome()
  browser.get("http://google.com/")
  </code></pre>
  
  <p>How do I remove this command-line flag in python selenium?</p>
