How to Block Websites on Android Using a Firewall

Firewalls provide security by monitoring access to your device and blocking data using a set of rules. Think of a firewall as a fence between you and the internet. Make sure to choose a no root firewall so that you don't have to root your Android device

One of the most downloaded firewalls for Android is NoRoot Firewall by Grey Shirts. With NoRoot Firewall, you can block sites depending on whether you’re using the internet through a Wi-Fi connection or a mobile data connection. You'll also receive notifications when an app attempts to access the internet. NoRoot Firewall is free to download, doesn't contain ads, and has no in-app purchases.

To block a website using NoRoot Firewall:

  1. Open NoRoot Firewall and swipe left on the gray bar at the top to select the Global Filters tab.

  2. Tap New Pre-Filter.

  3. Enter the full URL of the site you want to block including http or https in front of the domain name.

  4. In the Port line, tap the down arrow, then tap the asterisk (*).

    Tap the Wi-Fi icon if you want to block the website when the device is online; tap the Data icon if you want to block the website when using an LTE connection.
