Selenium Crashing: Chrome automation extension has crashed

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".

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.

Could it be some Chrome security issue?

I had the same problem, I could resolve it as the following: 1.Don’t run Chrome as Admin. 2.Don’t run your selenium App as Admin.
