Easy methods on how to block websites on Chrome

How to block yourself from a website on Chrome (desktop version)

1. Use an extension to block a website on google chrome

If you’re using an extension on desktop computers, all you need to do is add the URL of the site you want to block to the extension’s list.

Once you’ve done that, the site will be inaccessible from Chrome.

2. Block websites in incognito mode

If you want to block websites while browsing in incognito mode, you can go to the website and click on the lock icon in the address bar.

click the lock icon in address bar to block websites in incognito mode

In the menu that appears, scroll down and click “Site Settings.”

Under the “Permissions“ heading, find the “Notifications” section and change the setting to “Block.” This will prevent the website from sending you any more notifications.

If you want to allow notifications from the website again, you can change the setting to “Allow.”

3. Block a website on Chrome without an extension

There are two ways to block websites on Chrome, which are as follows:

Blocking a website by making changes in hosts files

If you want to edit your host file, you’ll need to find it first.

On a Windows computer, it’s located at C:\Windows\System32\drivers\etc\hosts.

For Mac users, it’s located at /private/etc/hosts.

Once you’ve found the file, open it in a text editor and add the following line at the bottom: www.example.com

Replace “www.example.com” with the URL of the site you want to block. Once you’ve saved the file, the site will be inaccessible from Chrome.

Blocking websites using a router’s IP address

If you want to block websites on all devices connected to your router, you can log into the router’s settings and blocklist the URL of the site you want to block.

This method is usually more effective than using an extension or editing the host’s file.

This is because it will prevent you from accessing the site even if the device isn’t using Chrome.

To find your router’s settings, you’ll need to look up the model number and then find the manual online.

Once you’ve found the manual, look for the section on website filtering or blocking.

The instructions will vary depending on the router, but they should be relatively easy to follow.

Once you’ve added the site to the blocklist, it should be inaccessible from any device connected to your router.

Keep in mind that this method won’t work if the device uses a VPN or proxy.

4. Use SafeSearch to block adult sites on Windows computers

You can enable SafeSearch in your search engine settings if you want to block adult sites. This will filter out any results that are inappropriate for children.To enable SafeSearch in Google, go to Google and click on “Settings” in the bottom right-hand corner.

go to google setting to turn on safesearch

In the menu that appears, click on “Search Settings.” Scroll down to the “SafeSearch filters” section and click the empty box beside “Turn on SafeSearch.”
