 // Classes for managing the SafeBrowsing interstitial pages.
 //
 // When a user is about to visit a page the SafeBrowsing system has deemed to
 // be malicious, either as malware or a phishing page, we show an interstitial
 // page with some options (go back, continue) to give the user a chance to avoid
 // the harmful page.
