This is not sent as part of the Anti-Phishing Extension’s normal operation when browsing the web.
  • Web sites (not URLs) visited when browsing the web. These are used to identify URLs that should be blocked within the site being visited and to provide contextual reports and popularity ranking information.

  • Very old versions of the Anti-Phishing Extension also collected MD5 hashes of URLs visited. This has been discontinued in recent versions.
