Here, we’ve selected three popular web browsers: Firefox, Opera, and Microsoft Edge.

Block Websites on Android with Web Blocker Apps

Web blocker apps are specifically designed to block websites on phones and tablets. The advantage of using them is that they block websites on your child’s device no matter what browser they use to surf the internet. Using web blockers, you don’t need to install add-ons and extensions on each and every browser your child uses. Moreover, you can let your child surf the internet with the popular Chrome browser since web blockers work well with Chrome. 

There are various web blocker apps on Google Play, but we recommend BlockSite. If you remember from the previous paragraphs, BlockSite is also a web browser extension. Below we’ll explain how to run BlockSite on your child’s Android phone or tablet. 

How to Block Websites on Android with BlockSite App

3. If the app asks for “Accessibility” permission, tap “Agree” to give permission
4. In the dashboard of the app, tap the green + sign 
5. In the panel that appears, you have a search bar. Enter the URL (address) of the website you want to block, like “facebook.com” 
6. The name of the website will appear in the search results. Tap it so that a green check mark appears 

Repeat this process for every URL you want to block. You can alternatively use BlockSite’s categories to block all the websites flagged as inappropriate. 

Block Websites on Android with Security Apps 

Mobile security apps, including firewalls and antiviruses, are primarily used to detect malware and stop hackers from accessing data on phones and tablets. However, some of them, like Mobile Security, also have website-blocking features. Below we’ll explain how to use Mobile Security on your child’s phone to block websites. 

How to Block Websites on Android with Mobile Security

To block websites with the Mobile Security app, you need to create an account for your child on Trend Micro, the production company of Mobile Security. Follow the steps below:

Block Websites on Android Using Host File 

Host file is a plain-text file in the Android operating system that maps hostnames and IP addresses. Modifying this file can block inappropriate websites on your child’s phone or tablet. However, you should be careful since the host file is crucial for your child’s phone to operate. 

How to Edit Host Files to Block Websites on Android

There are two methods for editing the host file: On a computer or on your child’s phone or tablet. Below we’ll explain both. 

On a Windows Computer

1. Download SDK Platform-Tools from the Platform-tools website 
2. Install the Android Debug Bridge command-line tool on your computer to control your child’s phone or tablet via USB 
3. Connect your child’s device to your computer via the USB port 
4. Open cmd prompt and enter “adb devices” 
5. Then type “adb pull /system/etc/hosts C:\hosts” (You can replace C with the drive you wish to copy the host file to) 
6. Go to the drive you saved the host file 
7. Open the host file with Notepad 
8. Add the IP “127.0.0.1” and the website URL you want to block. E.g. To block www.facebook.com, type 127.0.0.1 www.facebook.com 
9. Save the host file 
10. Now use cmd prompt again to type “adb push C:\hosts /system/etc/” to return the host file to your child’s device with Android Debug Bridge. (Replace C with the drive where you saved the host file to) 

On an Android Device 

1. If you don’t already have a file manager on your child’s device, download and install a file manager app like ES File Explorer File Manager from Google Play or any other app distribution platform on your child’s Android phone or tablet 
2. After installation, open ES File Explorer 
3. Tap the / button 
4. Look up the host file 
5. Tap the host file and then Open as > Text > ES Note Editor > Edit 
6. Add the IP “127.0.0.1” and the website URL you want to block. E.g. To block www.facebook.com, type 127.0.0.1 www.facebook.com 
7. Save and restart the phone for the settings to apply 

Block Websites on Android Devices with Parental Control Apps 

All the methods described so far have limitations. For example, by blocking websites using a web browser such as Firefox, your child can still access inappropriate websites via a different browser. In addition, although web blocker apps block websites on all browsers, your child can still freely surf the internet on another device. Similarly, security apps block websites on the same device installed. Finally, modifying the host file is a difficult task which may harm the device if done wrongly. 

As an alternative, we suggest parental control apps such as Safes which work on all phones, tablets, and computers running on Android, iOS, Windows, and macOS. Using Safes, you can monitor and control your child’s access to the internet remotely. That means after installing Safes Kids, a Safes companion app, on your child’s devices, you don’t need to touch them again to apply restrictions. 

How to Block Websites on Android Devices Using Safes 

To block websites on your child’s Android phone using Safes: 

1. You first need to create an account on Safes. You can do so using the Safes web panel or downloading the Safes app on your phone 
2. Then, you should create a profile for your child and add their devices 
3. To add your child’s device, you must download and install Safes Kids, the companion app, on your child’s device 
4. After that, you need to pair your child’s device with yours using a pairing code or a QR code given to you 

Now using your own account (again via the web panel or the Safes app), you can manage your child’s website access. To do so: 

1. Click “Web Filter” from the main menu 
2. Here, you have a list of categories of inappropriate websites. Each category contains thousands of inappropriate websites. By activating each category, protect your child from accessing harmful websites 
3. Or, you can add more websites to block (or make exceptions in the blocked categories) by entering their URLs (website addresses)

How do I block websites on Android Chrome without installing any app? 

If your child uses browsers such as Firefox and Opera, you can block their access to certain websites by installing add-ons. You can use your Microsoft account to restrict their access if they use Edge browser. However, these methods do not apply to Chrome, the most popular Android browser. In that case, you need to use alternatives which require installing a third-party app. But if you insist on not installing an app, you can try modifying the host file on your child’s Android phone, which is complicated and technical.
