In the latest test build of Chrome for Android appeared a blocker.
Block the browser will only hype. If testing is successful, the blocker can be expected in the stable version of the app for all users.
To enable just go to “site Settings” and select “Advertising”.
Install Chrome Canary right now and to cut unnecessary banners, but I want to remind you that the version is very unstable. If you are not afraid of application crashes, slow and glitches, then download in Google Play.
