SB has taken many steps to preserve privacy. If required, a full url is never sent
to Google, only a part-hash of the prefix, hidden with noise of other real part-hashes.
Firefox takes measures such as stripping out identifying parameters and since SBv4 (FF57+)
doesn't even use cookies. (#Turn on browser.safebrowsing.debug to monitor this activity)
