How to Block a Website on Any Phone or Browser

Updated 12 Nov 2026

The right way depends on your device and your browser. Here is one short answer for each, and a link to the full steps. Every path below comes from Apple, Google, Microsoft or Mozilla help pages.

iPhone and iPad (Safari and other browsers)

Screen Time is free and already on your device. Apple's iOS 26 page gives these steps:

1. Open Settings and tap Screen Time.
2. Tap Content & Privacy Restrictions and turn it on.
3. Tap App Store, Media, Web, & Games, then Web Content.
4. Choose Limit Adult Websites, tap Add Website under Never Allow, and type the address.

Apple's own-device pages for iOS 27 list no web steps. If you are on iOS 27, check your Settings first. Full steps: How to Block Websites on iPhone.

Android phone

Google's Digital Wellbeing page has a site timer for Chrome. It is a daily time limit, not a full block.

1. Open Settings and tap Digital Wellbeing.
2. Tap the chart, then tap Chrome. If you do not see it, tap Show all apps.
3. Next to the website, tap Set site timer.
4. Pick a time and tap OK.

Google's page does not say what happens when the timer runs out. Test it with a short time first. It also covers Chrome only.

If the phone is a child's, Google says Family Link can allow or block specific sites in Chrome. Full steps: How to Block Websites on Android.

Chrome on a computer

On the Google pages we read, Chrome has no setting where you add sites you want blocked on your own account. Here is what Google does describe:

• Extensions. You can add one from the Chrome Web Store. Google says you can't add extensions in Incognito mode or as a guest. Each extension also has an Allow in incognito switch. And you can turn any extension off in Manage extensions.
• Family Link. For a child's account, a parent can allow or block specific sites. Google says the child can sign out of Chrome, and then those settings don't apply.
• Work computers. Google says an administrator can use the URLBlocklist policy, which "stops web pages with prohibited URLs from loading."

Safari on a Mac

Apple's Mac page uses Screen Time again.

1. Choose Apple menu > System Settings, then click Screen Time. You may need to scroll down.
2. Click Content & Privacy, then App Store, Media, Web, & Games.
3. Under Safari, choose Limit Adult Websites and click Customize.
4. Click the add button below the Restricted list, type the address, then click Done.

Apple's page puts this setting under Safari. It does not say whether other browsers on the Mac follow it. Full steps: How to Block Websites on a Mac.

Firefox and Edge

Edge. Microsoft Family Safety can block sites in Edge. On the web, sign in to your Microsoft account and choose Family Safety. Find a family member and select Go to overview, then select Edge. Add the address under Blocked Sites. Microsoft says its filters only work in a supported browser, which is Edge for now.

Firefox. Mozilla says extensions add new features to Firefox. We found no built-in block list on the Mozilla pages we read. An extension you install yourself is one way to add one.

Why one browser's block is not enough

• A block in one browser does not cover your other browsers or your apps.
• You hold the off switch. On your own device, you can usually turn the block off in a few taps or clicks.
• On iPhone, anyone who knows the Screen Time passcode can change the list. Pick a passcode that someone else keeps.

A block works best when it covers the whole device and has a lock so you can't turn it off in a hurry.

Block any site with Mamori (free)

Mamori works on your iPhone, iPad or Android. You can add any site you like. It is free, and there is no limit.

1. Open Mamori and tap Block.
2. Under Add to your list, tap + A site.
3. Type the site address and add it.
4. Tap Lock and pick your lock.
5. Go to Home and tap Turn on.

To remove a site or turn protection off, you first get past your lock: a wait, a phrase you type, or a PIN a friend keeps. Adding a site is instant. Free waits are 15 seconds. Premium gives you longer locks, from 5 minutes to a week.

Mamori does not work on computers, so for Chrome, Safari on a Mac, Firefox or Edge, use the steps above.

On iPhone, the first time, iPhone asks you to switch Mamori on in Settings. You only do this once. When protection is off, nothing is blocked, and you can delete Mamori like any app.

FAQ

Can I block a website on my phone for free?

Yes. Screen Time on iPhone and Digital Wellbeing on Android come with your phone. Mamori is free too.

Does blocking a site delete anything?

No. It only stops the site from opening on that device. Your accounts stay as they are.

Will a block on my phone also work on my laptop?

Not with Mamori. It works on the phone or tablet it is on. Apple says that with Share Across Devices on, Screen Time limits and schedules apply to your iPhone, iPad and Mac. Its page does not say the same for your list of blocked sites.

Can I block a whole group of sites at once?

In Mamori, yes. The groups are Adult sites, Social media, Gambling, Dating, News, Games and Shopping. Each one blocks the apps and their websites.
