  /** SAFE BROWSING (SB)
      Safe Browsing has taken many steps to preserve privacy. *IF* required, a full url is never
      sent to Google, only a PART-hash of the prefix, and this is hidden with noise of other real
      PART-hashes. Google also swear it is anonymized and only used to flag malicious sites.
      Firefox also takes measures such as striping out identifying parameters and since SBv4 (FF57+)
      doesn't even use cookies. (#Turn on browser.safebrowsing.debug to monitor this activity)
