An internal Google Chrome page allows users to see all interstitial warnings or notifications that may be encountered while browsing the web with Chrome. An interstitial warning page is shown when Google wants to warn or notify a user about a particular risk or concern before a web page is loaded into the browser. Users can decide whether they want to ignore the warning and proceed, or go back to the previous page they were at. For example, Chrome 70 will have different warning interstitials than Chrome 71. For the Safe Browsing category, you can also see normal warning pages that are shown in Chrome for mobile and desktop.
