This is an extension for Chrome that allows you to keep your trusted sites away from the rest.

Great Barrier lets you save all of your frequently used and trusted websites. And when you receive a link from a webpage that is not in your whitelist and is unfamiliar to you, Great Barrier will direct you to an incognito window where you can view that page without affecting the current pages you have opened in your default browser. Hence, your sensitive pages are isolated from other sites.

This is helpful in case those untrusted links are spam or full of pop-up ads that can harm your device. And by directing you to incognito mode when you clicked them, those sites won't be saved in your web history.
