The main ways to block websites
You can block websites at three different levels: on a single device using browser settings or software, across all devices on your home network using your router, or on a work computer using your employer's tools. The method you choose depends on whether you want to block sites for yourself, for other people using your devices, or across your entire household.
Browser-level blocking works only in that specific browser on that specific device — if someone switches browsers or uses their phone, the block does not follow them. Router-level blocking affects every device connected to your Wi-Fi, including phones and tablets, but requires access to your router's admin panel. Device-level blocking through parental controls or third-party software can restrict what any user account on that computer sees, regardless of which browser they use.
Each method has trade-offs. Browser blocking is easiest to set up but easiest to bypass. Router blocking is harder to circumvent but affects everyone on your network, including guests. Software-based blocking on Windows or Mac gives you more control over specific accounts but requires installation and maintenance.
Key Takeaways
- Browser extensions like Freedom, Cold Turkey, or LeechBlock let you block websites in Chrome, Firefox, or Safari with a few clicks, but only in that browser on that device.
- Your router's admin panel can block websites for all devices on your Wi-Fi network at once, though the steps vary by router brand and model.
- Windows includes a built-in parental controls feature that can restrict websites for specific user accounts, and Mac offers similar controls through Screen Time.
- Third-party software like Cold Turkey Blocker or Freedom can block sites across your entire device and prevent you from disabling the block until the timer runs out.
- Blocking at the router level is hardest to bypass but affects all users, while browser-level blocking is easiest to set up but only works in one browser.
Blocking websites in your browser
The fastest way to block a website is through a browser extension. Chrome, Firefox, Safari, and Edge all support extensions that let you add sites to a blocklist in seconds. Popular options include Freedom, LeechBlock NG, Cold Turkey, and StayFocusd. You install the extension, add the websites you want to block, and the extension prevents you from visiting them.
To install an extension in Chrome: open the Chrome Web Store, search for the blocker you want, click "Add to Chrome," and confirm. Then click the extension icon in the top right corner of your browser, find the settings or options, and add your blocked sites. Most extensions let you set time limits (block sites between 9 AM and 5 PM, for example) or block them completely.
Browser blocking has a major limitation: it only works in that browser. If you block a site in Chrome but use Firefox, you can visit the blocked site in Firefox without restriction. Someone else using your computer in a different browser can also bypass the block. For this reason, browser extensions work best when you are blocking sites for yourself as a productivity tool, not when you are trying to restrict what others can see.
Blocking websites on your router
Blocking at the router level affects every device connected to your Wi-Fi — phones, tablets, laptops, smart TVs, everything. This is the most effective way to block sites for everyone on your network at once. The exact steps depend on your router brand, but the general process is the same: log into your router's admin panel, find the parental controls or content filtering section, and add websites to a blocklist.
To access your router: open a web browser and type 192.168.1.1 or 192.168.0.1 into the address bar. You will be prompted to log in with a username and password — if you have not changed these, they are usually printed on the router itself or in the manual. Once logged in, look for a section labeled "Parental Controls," "Content Filtering," "Access Control," or "Security." The exact name varies by manufacturer.
In that section, you can usually enter website addresses or domain names you want to block. Some routers let you block by category (adult content, gambling, social media) rather than individual sites. After you save your changes, the router will block those sites for all connected devices. The downside is that someone with access to the router's admin password can disable the block, and the process is more technical than using a browser extension.
If your router does not have a built-in content filter, you can use a DNS-based blocking service like OpenDNS or Cloudflare for Families. These services intercept DNS requests (the system that translates website names into addresses) and block sites before your device even tries to connect. You change your router's DNS settings to point to their servers instead of your internet provider's, and the blocking happens automatically across all devices.
Blocking websites on Windows
Windows 10 and Windows 11 include a built-in parental controls feature called Family Safety that can restrict websites for specific user accounts. This works across all browsers on that account, so someone cannot bypass it by switching from Edge to Chrome. To set it up, you need a Microsoft account and the ability to create or modify user accounts on the computer.
To enable Family Safety: open Settings, go to Accounts, select Family and other users, and click "Add a family member." Create a child account or add an existing Microsoft account. Once the account is set up, go back to Family Safety, select that account, and turn on "Web and search." You can then set content restrictions (block adult content, for example) or add specific websites to a blocklist. The person using that account will see a message when they try to visit a blocked site.
For more control, third-party software like Cold Turkey Blocker or Freedom can block websites across your entire device and prevent you from disabling the block until a timer runs out. These are designed for productivity — you set a block for a specific time period, and you cannot turn it off early even if you restart your computer. This is more restrictive than browser extensions but more reliable if you are trying to enforce a block on yourself.
Blocking websites on Mac
macOS includes a feature called Screen Time that can restrict websites for specific user accounts. Open System Settings, go to Screen Time, select the account you want to restrict, and click "App Limits" or "Communication Limits." You can set content restrictions or add specific websites to a blocklist. Like Windows Family Safety, this works across all browsers on that account.
If you want stronger restrictions that you cannot easily disable, Freedom and Cold Turkey both work on Mac and offer the same timer-based blocking as on Windows. You can also use browser extensions like LeechBlock NG or Freedom in Safari, Chrome, or Firefox, though these only block within that specific browser.
Blocking websites on phones and tablets
On iPhone and iPad, open Settings, go to Screen Time, tap "Content & Privacy Restrictions," and turn on the toggle. Then tap "Allowed Apps" or "Content Restrictions" to block categories of content, or go to "Websites" to add specific sites to a blocklist. You can set a Screen Time passcode so someone cannot disable the restrictions without the code.
On Android, the process varies by manufacturer and Android version. Most phones have a built-in parental controls feature in Settings — look for "Parental Controls," "Digital Wellbeing," or "Family Link." You can also use Google Family Link, which is Google's parental control app and works across multiple Android devices. Install the app, set up a supervised account, and add websites to a blocklist from the parent dashboard.
Browser extensions for mobile are limited — most phones do not support extensions the way desktop browsers do. For stronger mobile blocking, use your phone's built-in parental controls or a third-party app like Freedom, which has mobile versions for both iOS and Android.
Comparing blocking methods by situation
| Situation | Best Method | Why |
|---|---|---|
| Blocking sites for yourself as a productivity tool | Browser extension or Cold Turkey | Quick to set up, timer-based blocking prevents you from disabling it early |
| Blocking sites for other people on your home network | Router-level blocking or parental controls | Works across all devices and browsers, harder to bypass |
| Blocking sites on a specific user account | Windows Family Safety or Mac Screen Time | Built-in, works across all browsers, requires account password to disable |
| Blocking sites across your entire home network | Router blocking or DNS-based service | Affects all devices at once, no per-device setup needed |
| Blocking sites on a work computer | Your employer's tools or IT department | Your employer likely has blocking software already installed; check with IT first |
What happens when someone tries to visit a blocked site
When a blocked site is accessed, the user sees one of several messages depending on the blocking method. Browser extensions usually show a popup or redirect page saying the site is blocked. Router-level blocking typically shows a blank page or a message from your router manufacturer. Parental controls on Windows or Mac show a message that the site is restricted and may offer an option to request permission from the account owner.
Some blocking tools let you customize the message — you can set a redirect page with your own text, or show a motivational message instead of a blank page. This is useful if you are blocking sites for someone else and want to explain why the block is in place.
Frequently Asked Questions
Can someone bypass a website block?
It depends on the method. Browser extensions are easiest to bypass — someone can uninstall the extension or use a different browser. Router-level blocking is harder to bypass but can be disabled if someone knows the admin password. Parental controls on Windows or Mac require the account password to disable. The most difficult to bypass are timer-based blockers like Cold Turkey, which cannot be disabled until the timer runs out, even if you restart your computer.
Will blocking a website slow down my internet?
No. Browser extensions and parental controls have minimal impact on speed. Router-level blocking and DNS-based blocking may add a tiny delay (milliseconds) as the router or DNS service checks each website, but you will not notice it in normal use.
Can I block a website on just one device if I share my Wi-Fi?
Yes. Use a browser extension or parental controls on that specific device. Router-level blocking affects all devices on your network, so if you only want to block a site on one phone or laptop, use the device's own settings instead.
What if I block a site by mistake and need to unblock it?
The process depends on the method. For browser extensions, open the extension settings and remove the site from the blocklist. For router blocking, log into your router's admin panel and remove the site from the blocklist. For parental controls, open the settings and remove the site from restrictions. If you set a timer-based block in Cold Turkey or Freedom, you have to wait until the timer runs out unless you know the override password.
Can I block a website on my work computer?
Check with your IT department first — most workplaces have their own blocking software already installed, and installing your own software may violate company policy. If your employer allows it, you can use a browser extension on your work browser, but router-level blocking would affect your entire home network, not just work devices.
