title: Selenium Crashing: Chrome automation extension has crashed
body: <p>I am using Selenium web drivers, and today, for no apparant reason I started getting an error with the message"Chrome Automation Extension has crashed.  Click this balloon to reload the extension".</p>
  
  <p>The only thing I can think of is I added an extension for testing XPath to Chrome today.  But it was working fine for a while after I added that.</p>
  
  <p>Could it be some Chrome security issue?</p>
