The fastest way to block a site on Android

You can block a website on Android using your phone's built-in browser settings, a third-party app, or your network settings. The method you choose depends on whether you want to block the site across all apps, just in your browser, or for a specific user on a shared device.

The simplest approach for most people is to use a browser-level blocker in Chrome or Firefox, since that's where most browsing happens. If you need to block a site across your entire phone — including in apps — you'll need to use a dedicated blocking app or adjust your router settings at home.

This guide walks you through each method so you can pick the one that fits your situation.

Key Takeaways

  • Chrome and Firefox both let you block sites directly in their settings without installing anything extra.
  • Third-party blocking apps like Freedom, Cold Turkey, or AppBlock work across your whole phone, not just the browser.
  • Parental control apps like Google Family Link let one person manage what another person can see on a shared device.
  • Router-level blocking affects all devices on your home network, so it works even if someone tries to use a different browser or app.

Blocking a site in Chrome

Chrome doesn't have a built-in block list, but you can use the SafeSearch filter to block adult content, or install an extension that does the blocking for you. The most straightforward method is to use a free extension like BlockSite or LeechBlock.

Open Chrome and go to the Google Play Store. Search for "BlockSite" and install it. Once installed, open the extension, tap the menu icon, and add the website URL you want to block. The extension will prevent that site from loading whenever you try to visit it in Chrome.

If you want to block adult content across Chrome without an extension, open Chrome settings, scroll to "Safety," and turn on SafeSearch. This filters explicit results from Google searches and blocks adult sites from loading, though it's not foolproof.

Blocking a site in Firefox

Firefox on Android doesn't have a native blocking feature either, but you can install the uBlock Origin extension, which blocks both ads and specific websites. Open Firefox, tap the menu icon (three horizontal lines), go to "Add-ons," search for uBlock Origin, and install it.

Once installed, visit the website you want to block. Tap the uBlock Origin icon in the address bar, then tap the power icon to block that entire domain. The next time you try to visit that site, Firefox will stop it from loading.

Alternatively, you can use the same BlockSite extension available in Chrome — it works in Firefox too and gives you a dashboard to manage all your blocked sites in one place.

Using a dedicated blocking app for your whole phone

If you need to block sites across your entire phone — not just in the browser — you'll need a dedicated app. These apps work by creating a VPN connection or using Android's device administrator feature to intercept all traffic, including apps.

Freedom is one of the most popular options. Download it from the Google Play Store, create an account, and add the websites or apps you want to block. You can set schedules so sites are only blocked during certain hours, or block them permanently. Freedom costs money but offers a free trial.

Cold Turkey and AppBlock work similarly and are free or low-cost. AppBlock is lighter on your phone's battery and works well if you just want to block a few sites. Cold Turkey is more powerful if you need to block apps too, not just websites.

When you install any of these apps, Android will ask you to grant device administrator access. This is normal — the app needs this permission to actually block sites system-wide. You can revoke the permission anytime by going to Settings > Security > Device Admin Apps and unchecking the app.

Setting up parental controls for a shared device

If you're setting up a phone for a child or another family member and want to control what they can see, use Google Family Link. This is Google's official parental control tool and works across Android phones and Chromebooks.

On your own phone, download Google Family Link and create a family group. Add the other person's Google account to the group. Then on their phone, sign in with their account. You'll now see their phone in your Family Link dashboard.

In the Family Link app on your phone, tap their device, go to "App activity," and scroll to "Blocked sites." Tap the plus icon and enter the website URL. You can also set screen time limits, control app downloads, and see their location. The person using the device will see a notification that their parent or guardian has set restrictions.

Blocking sites at your router level

If you want to block a site for everyone on your home network — including guests — you can do it from your router's settings. This works on any device that connects to your Wi-Fi, whether it's Android, iPhone, laptop, or tablet.

Open a web browser on any computer or phone connected to your Wi-Fi and type your router's IP address into the address bar. This is usually 192.168.1.1 or 192.168.0.1, but check your router's manual or the sticker on the back if those don't work. Log in with your router's admin username and password (also on the sticker if you haven't changed it).

Look for a section called "Parental Controls," "Access Control," or "Content Filtering" — the exact name varies by router brand. Add the website URL to the blocked list. Save your changes, and that site will no longer load on any device connected to your Wi-Fi.

The downside is that someone can bypass this by using mobile data instead of Wi-Fi, or by changing their DNS settings. But for a household where everyone is using the same network, it's the most comprehensive approach.

What to do if a site keeps loading despite blocking

If a site still loads after you've blocked it, the most common reason is that you blocked the wrong URL. For example, blocking "facebook.com" won't block "m.facebook.com" or "www.facebook.com" — you may need to block all three versions.

Check the exact URL in your blocker's settings. If you're using a browser extension, make sure it's actually enabled — tap the extension icon in your address bar and confirm it shows as active. If you're using a dedicated app, check that you granted it device administrator access and that the app itself hasn't been disabled in your phone's settings.

If you're blocking at the router level and the site still loads, someone may be using mobile data or a different Wi-Fi network. You can also try clearing your browser cache, since sometimes a cached version of a site will load even if the live site is blocked.

Frequently Asked Questions

Can I block a site on Android without installing an app?

Yes, if you only need to block it in your browser. Chrome and Firefox both support extensions like BlockSite that work without a separate app. However, if you need to block a site across your entire phone including in other apps, you'll need either a dedicated blocking app or access to your router settings.

Will blocking a site stop it from working in apps too?

It depends on the method. Browser extensions only block the site in that browser. Dedicated apps like Freedom and AppBlock block sites system-wide. Router-level blocking also works across all apps and browsers on your network, but only when connected to that Wi-Fi.

Can someone unblock a site I've blocked on their phone?

If you're using Google Family Link, the person can't unblock sites without your permission — you control the restrictions from your phone. If you're using a regular blocking app on their phone, they can uninstall it if they have access to the phone's settings. Router-level blocking is hardest to bypass without changing networks.

Does blocking a site use more battery?

Blocking apps that use a VPN connection do use slightly more battery because they're constantly monitoring traffic. Browser extensions use almost no extra battery. Router-level blocking uses no battery at all on your phone.

What's the difference between blocking and filtering?

Blocking stops a site from loading entirely. Filtering (like SafeSearch) lets the site load but removes certain content from it. Filtering is less strict and easier to bypass, but it uses less battery and doesn't require special permissions.
