What blocking a website means
Blocking a website means preventing your device from loading a specific web address. When you block a site, your browser or device stops you from visiting it — the page straightforward will not load, even if you type the address directly into the search bar. The block stays in place until you remove it.
Blocking works differently depending on what you are trying to do. You might block a site to stop distracting yourself during work, to prevent someone else from visiting it on a shared device, or to keep a child from accessing content you consider unsafe. The method you use depends on which of these situations matches yours.
Key Takeaways
- Browser extensions like Freedom, Cold Turkey, or LeechBlock are the simplest way to block sites on your own device if you want to stop yourself from visiting them.
- Your device's parental controls or screen time settings let you block sites for other users, including children, and usually require a separate password to remove the block.
- Your router settings can block sites across all devices on your home network at once, which is useful if you manage internet access for a household.
- Blocking a site on your device does not prevent someone with technical knowledge from removing the block if they have access to your device.
Blocking sites on Windows using browser extensions
The easiest method on Windows is to install a browser extension that blocks sites you choose. Open your browser — Chrome, Edge, or Firefox — and search the extension store for blockers like Freedom, Cold Turkey Blocker, or LeechBlock NG. Install the extension, then open its settings and add the websites you want to block by typing their addresses.
Most extensions let you set a schedule: you can block sites only during work hours, for example, or every day from 9 a.m. to 5 p.m. Some extensions also let you set a password so that you cannot unblock a site on impulse — you have to wait until the scheduled block time ends. This works well if you are trying to limit your own browsing rather than control someone else's access.
The downside is that extensions only work in that specific browser. If you use Chrome to block Reddit but then open Firefox, you can visit Reddit in Firefox without any block. If you want to block a site across all browsers on your Windows computer, you need to use your device's parental controls instead.
Blocking sites on Mac using parental controls
On a Mac, open System Settings, then select Screen Time in the left sidebar. Click Content & Privacy, then Web Content. Choose Limit Adult Websites, and you will see a list of restricted sites that Mac blocks by default. Click Customize to add specific websites you want to block.
Type the web address of each site you want to block — for example, reddit.com or youtube.com — and click the plus sign to add it to the list. When you are done, click Done. The sites you added will now be blocked across all browsers on that Mac account.
If you are setting this up to control access for someone else, create a separate user account for them, then set up Screen Time on that account with a password only you know. That person will not be able to remove the blocks without your password. If you forget the password, you will need to reset it through your Apple ID.
Blocking sites on Windows using parental controls
On Windows 10 or 11, open Settings and go to Accounts, then Family & other users. If you are setting this up for yourself, select your account and click App & website restrictions. If you are setting it up for someone else, first create a child account, then select that account and click App & website restrictions.
Turn on the toggle for Restrict websites. You will see a list of categories — Mature content, Drugs, Weapons, and others — that Windows blocks by default. Below that, you can add specific websites by typing their address in the box labeled "Block these websites" and clicking Add. Windows will block those sites across all browsers on that account.
If you set this up on a child account, you control it from your own account using Family settings. The child cannot remove the blocks without access to your account password. On your own account, you can remove blocks whenever you want, so this method works best if you want a gentle reminder rather than a hard barrier.
Blocking sites at the router level
If you want to block a website for everyone on your home network — across all devices, all browsers, and all accounts — you can do it through your router settings. This is the most powerful method because no one can bypass it by switching browsers or devices, but it requires you to access your router's admin panel, which takes a few more steps.
Open a web browser 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 label or manual if neither works. Log in using your router's admin username and password — if you have never changed these, they are usually printed on the router itself or in the manual.
Once you are logged in, look for a section called Parental Controls, Content Filtering, or Access Control. The exact name varies by router brand. Add the websites you want to block by typing their addresses. Save your changes. From that point on, no device on your network can visit those sites, regardless of which browser they use or which account they log into.
The trade-off is that if you forget your router password, you may need to reset the entire router to factory settings, which erases all your custom settings. Write down your router password somewhere safe before you make changes.
Blocking sites on your phone or tablet
On an iPhone or iPad, open Settings and go to Screen Time. Tap Content & Privacy Restrictions, then Web Content. Choose Limit Adult Websites and add specific sites by tapping the plus sign and typing the web address. These blocks explore across all browsers on that device.
On an Android phone or tablet, the process depends on which version you have and which launcher you use. The simplest method is to install a browser extension blocker — most Android browsers support extensions the same way desktop browsers do — or to use your phone's built-in parental controls through Google Family Link if you set up a child account.
If you are blocking sites on your own phone to limit distractions, a browser extension is usually faster than digging into settings. If you are blocking sites on a child's device, use the device's parental controls and set a password only you know.
What happens when you try to visit a blocked site
When you try to load a blocked website, you will see an error message instead of the page. The exact message depends on where the block is set. A browser extension might show a message like "This site is blocked" with a timer showing when the block ends. Parental controls usually show a message saying the site is restricted and asking for a password to proceed. A router-level block typically shows a generic error page.
In all cases, the page does not load. You cannot see any content from the blocked site, and you cannot bypass the block by typing a different version of the address — if you block reddit.com, typing www.reddit.com or old.reddit.com will also be blocked.
Frequently Asked Questions
Can I block a site on just one browser?
Yes, using a browser extension. Extensions only work in the browser where you install them, so you can block a site in Chrome but still visit it in Firefox. If you want to block across all browsers, use your device's parental controls or router settings instead.
What if I forget the password to unblock a site?
On a Mac, you can reset your Screen Time password using your Apple ID. On Windows, you can reset parental controls through your Microsoft account. For a router, you may need to reset it to factory settings, which erases all custom settings. Write down any passwords you set before you forget them.
Can someone remove a block I set on a shared device?
If you set the block on a separate user account with a password only you know, they cannot remove it without your password. If you set it on a shared account, anyone with access to that account can remove the block. Router-level blocks cannot be removed without access to the router's admin panel.
Does blocking a site hide my browsing history?
No. Blocking prevents you from visiting a site, but it does not hide what you have already visited. If you want to delete your browsing history, you need to clear it separately in your browser settings.
Will a VPN let someone bypass a blocked site?
A VPN can sometimes bypass browser extension blocks, but it usually cannot bypass parental controls or router-level blocks. If you are trying to control access on a device you manage, a router-level block is the hardest to bypass.
