This is the app that makes it easier to block websites. You can browse the web, and avoid websites like Facebook, Twitter, and other popular sites. 

It is useful for users that don't want to visit the sites they want to block but don't have time to write the URL. You can simply add single words such as “Twitter” or “Facebook” and it will block all URLs for those domains. 

This extension also features a pause function that you can time, so you can allow yourself short breaks if you need to open an urgent link from your blocked sites.
