Chrome blocks most pop-ups automatically — here's what that means and what you can do

Chrome comes with a built-in pop-up blocker that is turned on by default. This means most unwanted windows and tabs are already stopped before they appear. However, the blocker is not perfect — some pop-ups still get through, and occasionally you may want to allow pop-ups on a specific website. You control these settings in Chrome's site permissions menu, and the process takes less than a minute.

The blocker works by preventing websites from opening new windows or tabs without your direct action. If a site tries to open a pop-up when you have not clicked a link or button, Chrome stops it. You will see a small notification at the top of the page telling you a pop-up was blocked. You can then choose to view it or ignore it.

Key Takeaways

  • Chrome's pop-up blocker is on by default and blocks most unwanted windows automatically.
  • When a pop-up is blocked, you will see a notification at the top of the page that lets you view it if you want.
  • You can turn the blocker off entirely in Settings, though this is not recommended because it exposes you to more unwanted content.
  • You can allow pop-ups on specific websites while keeping the blocker on for everywhere else.
  • Some pop-ups are actually new tabs or windows the website opens legitimately, and these may not be blocked even when the blocker is on.

Check whether the pop-up blocker is on

Open Chrome and look at the top right corner of the window. Click the three vertical dots (called the menu button) and select Settings. On the left side, click Privacy and security, then click Site settings.

Scroll down until you see Pop-ups and redirects. Click it. At the top, you will see a toggle or dropdown that says either "Blocked (recommended)" or "Allowed". If it says "Blocked (recommended)", your pop-up blocker is on and working. If it says "Allowed", pop-ups are not being blocked.

Turn the pop-up blocker on if it is off

If you found that pop-ups are set to "Allowed", click the toggle or dropdown and change it to Blocked. The change takes effect when ready. You do not need to restart Chrome.

Turning the blocker on will stop most new windows and tabs from opening without your action. Some websites may not work correctly if they rely on pop-ups for important features, but this is rare. If you find a website that needs pop-ups to function, you can allow them for just that site instead of turning off the blocker entirely.

Allow pop-ups on a specific website

If you visit a website that you trust and want to allow pop-ups there, you can add it to an exception list. Visit the website, and if a pop-up is blocked, look at the top of the page. You will see a small notification that says something like "Pop-up blocked" with an X button next to it. Click the notification itself (not the X) to see options.

You will see a button that says Always allow pop-ups and redirects on [website name]. Click it. From now on, that website can open pop-ups without being blocked. The blocker remains on for all other websites.

If no pop-up was blocked on that visit, you can add the site manually. Go back to Settings > Privacy and security > Site settings > Pop-ups and redirects. Under "Allow", click Add and type the website address (for example, example.com). Click Add again to save it.

Remove a website from the pop-up exception list

If you previously allowed pop-ups on a website and want to block them again, go to Settings > Privacy and security > Site settings > Pop-ups and redirects. Look for the website under the "Allow" section. Click the trash icon next to it to remove it from the list.

The website will when ready go back to having its pop-ups blocked. You can add it back to the exception list anytime using the same method described above.

Understand what the blocker does and does not stop

Chrome's pop-up blocker stops new windows and tabs that open without you clicking something. This includes most advertising pop-ups, fake warning messages, and unwanted redirects. However, it does not stop pop-ups that appear because you clicked a link or button on the page — those are considered intentional.

Some websites open new tabs or windows when you click a normal link, and these will not be blocked because you triggered them. If a website is opening too many windows when you click links, that is a sign the site may not be trustworthy. You can also close unwanted tabs by clicking the X on the tab itself.

The blocker also does not stop notifications, ads that appear within the page itself, or content that loads inside the page without opening a new window. If you want to control those, you would need to use a separate ad blocker extension.

Turn off the pop-up blocker if you need to (not recommended)

If you want to turn off the blocker entirely, go to Settings > Privacy and security > Site settings > Pop-ups and redirects and change the setting from "Blocked" to Allowed. This will let all websites open pop-ups without restriction.

Turning off the blocker is not recommended because it exposes you to unwanted content, fake warnings, and potentially harmful redirects. If a website is not working because of the blocker, it is safer to add just that website to the exception list rather than turning off protection for all sites.

Frequently Asked Questions

Why do I still see pop-ups even though the blocker is on?

Some pop-ups are triggered by your own actions — clicking a link, submitting a form, or hovering over content. These are not blocked because you initiated them. Others may be ads or content that loads within the page itself rather than opening a new window. The blocker only stops new windows and tabs that open without your action.

Can I block pop-ups on my phone or tablet?

Chrome on Android and iOS also has a pop-up blocker that works the same way as the desktop version. On mobile, tap the three dots in the bottom right corner, go to Settings, then Privacy, and toggle Pop-ups off. The process is similar but the menu layout is slightly different because of the smaller screen.

What is the difference between a pop-up and a pop-under?

A pop-up appears in front of the page you are viewing. A pop-under opens behind your current window so you do not see it until you close or minimize Chrome. Chrome's blocker stops both types. You may not notice a pop-under until you close the browser and see it was open in the background.

Will blocking pop-ups break websites I use regularly?

Most modern websites do not rely on pop-ups for core features, so the blocker should not cause problems. If a website stops working correctly, you can add it to the exception list to allow pop-ups just for that site. This is safer than turning off the blocker entirely.

Do I need an extension to block pop-ups better than Chrome's built-in blocker?

Chrome's built-in blocker handles most pop-ups effectively. Extensions that claim to block pop-ups better often block other content too, like ads within pages or notifications. If you want more control over ads and notifications, an ad blocker extension may help, but it is separate from pop-up blocking.
