Do you not want your browser going to a site that might be malicious?

You'll definitely want to block anything like that from your browsers. Read on to learn more about blocking websites on Mac, Windows, iPad, iPhone, and Android.

Block Websites in All Web Browsers

Block websites from all web browsers by editing the "Hosts" files on Windows and Mac. Editing the "Hosts" file takes a little work, but this wikiHow article guides you through the process so it's easier to block websites in all your web browsers. For iPad, iPhone, and Mac, use Screen Time to block websites.

  1. Press the Win key and enter Notepad . Right-click on the app and select Run as administrator . This option will open Notepad using your administrator privileges. If you don't open Notepad in administrator mode, you won't be able to edit the "hosts" file.
    • On a laptop with a trackpad instead of a traditional mouse, use two fingers to tap the trackpad instead of right-clicking.
  2. Doing so will confirm your decision and open Notepad.

  3. You'll find Open in the File drop-down menu.
  4. In the window that opens after clicking Open... , do the following:
    • Click the This PC tab on the left side of the window.
    • Double-click your computer's hard drive (e.g., OS (C:) ).
    • Double-click the Windows folder.
    • Scroll down and double-click the System32 folder.
    • Scroll down and double-click the drivers folder.
    • Double-click the etc folder.
  5. Click the "Text Documents" drop-down box near the bottom of the window, then click All Files in the drop-down menu. You should see several files appear in the window.
  6. Right-click the "hosts" file, then do the following:
    • Click Properties
    • Click Security
    • Click Edit
    • Check the "Full Control" box.
    • Click OK , then click Yes when prompted.
    • Click OK to exit the Properties window.
  7. This will open the "hosts" file in Notepad, allowing you to view and edit its contents.
  8. You'll see two "localhost" lines of text here.
  9. It will say either "::1 localhost" or "127.0.0.1 localhost" at the bottom of the page. Your cursor must be directly below the last line of text on this page.
    • Be careful not to delete anything that is already in the hosts file.
  10. This is the loopback address to your own computer, which is what will return an error page in your web browser when someone tries to visit the blocked site.
  11. For example, if you wanted to block Google, you would type www.google.com .
    • If you're blocking sites on Google Chrome, you'll need to place a space and then the "www.[site].com" version of the website's address after the "[site].com" version. To block Facebook, for example, you would type in 127.0.0.1 facebook.com www.facebook.com .
  12. This moves your cursor to a new line. The code you entered will tell your computer to redirect the website to your loopback address instead.
    • You can add as many sites as you want to block, one per line, using the same number (127.0.0.1) as before.
    • If you want to be as thorough as possible, enter different variations of the address (e.g., "google.com" and "https://www.google.com/") as well.
  13. Your changes won't be saved if you simply save using File > Save , so do the following to confirm your changes:
    • Click File
    • Click Save As...
    • Click Text Documents , then click All Files in the drop-down menu.
    • Click the "hosts" file.
    • Click Save
    • Click Yes when prompted.

    sudo nano /etc/hosts

  5. Type in the password that you use to log into your Mac, then press ⏎ Return .
    • Terminal won't display the password characters as you type them.
  6. To do so, press the ↓ key until the cursor is below the last line of text on the page.
  7. Type 127.0.0.1 into the blank line. This is the loopback address to your own computer. [1]
  8. The cursor will move to the right.
    • Don't press ⏎ Return yet.
  9. For example, if you wanted to block Google, you would type www.google.com .
    • This line would then read 127.0.0.1 www.google.com .
    • If you want to be as thorough as possible, enter different variations of the address (e.g., "google.com" and "https://www.google.com/") as well.
    • If you're blocking sites on Google Chrome, you'll need to place a space and then the "www.[site].com" version of the website's address after the "[site].com" version. To block Facebook, for example, you would type in 127.0.0.1 facebook.com www.facebook.com .
  10. This will tell your computer to redirect the website to your loopback address instead.
    • You can add as many sites as you want to block, one per line, using the same number (127.0.0.1) as before.
  11. This is the command to exit the hosts file in the text editor. It will prompt you if you'd like to save your changes.
  12. It will then ask you what filename you'd like to save it as. You want to overwrite the original hosts file, so don't change the filename.
  13. This will save your changes to the original hosts file. Doing so exits the text editor and returns you to the main Terminal window. The website you added will now be unreachable in any web browser on the computer.
