Great extension. Much more useful than just green indicator in the address bar or other extensions which track just the main page without third-party content.

But it's still hard to validate certificate which Patrol is suspicious about.
It would be a great feature to add on-demand (button?) validation via "https://www.grc.com/fingerprints.htm" or Perspectives notaries in the "certificate changed" dialog.
