Chrome blocks most pop-ups automatically — you just need to check your settings

Chrome has a built-in pop-up blocker that turns on by default. Most unwanted pop-ups never reach your screen because the browser stops them before they load. If pop-ups are still getting through, your settings may have been changed, or you may have accidentally allowed them for a specific website. You can see which sites have permission to show pop-ups, remove that permission, and adjust how strictly Chrome blocks them.

The steps differ slightly depending on whether you use Chrome on Windows, Mac, or a Chromebook, but the settings menu is the same across all versions.

Key Takeaways

  • Chrome's pop-up blocker is on by default and blocks most unwanted pop-ups without any action from you.
  • If pop-ups appear, you may have accidentally allowed them for that website, and you can remove that permission in Chrome's site settings.
  • You can see a list of every website you've given pop-up permission to and remove individual sites or block all pop-ups entirely.
  • Some websites need pop-ups to work properly (like online banking or document editors), so you can allow pop-ups for those sites while blocking them everywhere else.

Check if pop-ups are actually blocked

When Chrome blocks a pop-up, it shows a small notification at the top right of the address bar — usually a box icon with a number inside it, like a badge. This tells you how many pop-ups were blocked on that page. Click the icon to see what was blocked and choose whether to allow it.

If you don't see this notification, the pop-ups may not be reaching Chrome at all (they're blocked before the page loads), or they may be coming from a website you've already given permission to. If pop-ups keep appearing without this notification, they're likely from a site you've allowed.

Remove pop-up permission from a specific website

When you visit a website, Chrome may ask if you want to allow pop-ups. If you click "Allow" by mistake, that website can show pop-ups whenever you visit it. To take that permission away, open the website, then click the lock icon or information icon next to the address bar at the top left.

A menu will drop down. Look for "Pop-ups and redirects" or "Pop-ups" in the list. Click the dropdown next to it and change it from "Allow" to "Block". Close the menu — the change saves automatically. The next time you visit that website, pop-ups will be blocked again.

If you can't find the pop-ups setting in that menu, try clicking the three vertical dots (menu button) at the top right of Chrome, then go to Settings > Privacy and security > Site settings > Pop-ups and redirects. You'll see a list of every website you've given pop-up permission to. Click any site name and change its setting to "Block".

Block all pop-ups or allow them for specific sites

To see your overall pop-up blocker setting, open Chrome's menu (three vertical dots at top right), go to Settings, then click Privacy and security on the left side. Select Site settings, then Pop-ups and redirects.

At the top of this page, you'll see a toggle or dropdown that controls the default behavior. If it says "Blocked" (or shows a toggle that's on), pop-ups are blocked by default across all websites. If it says "Allowed", pop-ups are allowed everywhere, and you should change this to "Blocked".

Below that setting, you'll see two lists: Allowed (websites that can show pop-ups) and Blocked (websites you've specifically blocked). You can remove any site from the Allowed list by clicking the three dots next to its name and selecting "Remove". You can also add a website to the Blocked list by clicking "Add" and typing the website address.

Allow pop-ups for websites that need them

Some legitimate websites require pop-ups to function — online banking, document editors, video players, and appointment schedulers often use them. If a website tells you it needs pop-ups and you trust it, you can allow them just for that site.

Visit the website, click the lock or information icon next to the address bar, find "Pop-ups and redirects", and change it to "Allow". Or go to Settings > Privacy and security > Site settings > Pop-ups and redirects, click "Add" under the Allowed section, type the website address, and click "Add" again. From then on, that website can show pop-ups, but others cannot.

Clear pop-up permissions you no longer need

Over time, you may accumulate a long list of websites you've allowed pop-ups for. You can clear all of them at once or remove them one by one. Go to Settings > Privacy and security > Site settings > Pop-ups and redirects. Under the "Allowed" section, you can click the three dots next to any individual site and select "Remove", or you can go back to Privacy and security and click Clear browsing data to reset all site permissions at once (select "Cookies and other site data" and choose your time range).

Be aware that clearing all site data will also reset permissions for other features like location, camera, and microphone, not just pop-ups. If you only want to remove pop-up permissions, remove them individually from the Pop-ups and redirects page instead.

What to do if pop-ups still appear

If pop-ups keep appearing even after you've blocked them, they may be coming from an extension you've installed. Some browser extensions inject ads or pop-ups into websites. Open Chrome's menu, go to Extensions, and look through your list. Remove any extension you don't recognize or don't use anymore. You can also disable an extension temporarily by clicking the toggle next to its name to see if the pop-ups stop.

Another possibility is that the pop-ups are coming from a website you visit frequently and have allowed. Check the "Allowed" list in Settings > Privacy and security > Site settings > Pop-ups and redirects and remove any site you don't trust. If you're still seeing pop-ups after checking extensions and site permissions, restart Chrome completely — close all windows and reopen the browser.

Frequently Asked Questions

Why does Chrome ask me to allow pop-ups on some websites?

Websites can request permission to show pop-ups, and Chrome asks you before granting it. Some sites need this for legitimate features like chat windows or notifications. Others ask because they want to show ads. You can always click "Block" when prompted, and you can change your answer later in site settings.

Can I block pop-ups on mobile Chrome?

Yes. On Android or iPhone, open Chrome, tap the three dots at the bottom right, go to Settings, tap Site settings, then Pop-ups and redirects. The toggle should be off (blocked). If you've allowed pop-ups for a specific site, you can remove that permission the same way.

Will blocking pop-ups break websites I use?

Rarely. Most websites work fine with pop-ups blocked. If a website genuinely needs pop-ups and doesn't work, you'll usually see a message telling you to allow them. You can then allow pop-ups just for that site without affecting others.

What's the difference between pop-ups and notifications?

Pop-ups are windows that open on top of a webpage. Notifications are messages that appear in the corner of your screen, usually from websites or apps. Chrome's pop-up blocker only controls pop-ups. To block notifications, go to Settings > Privacy and security > Site settings > Notifications.

Do I need an extension to block pop-ups better?

No. Chrome's built-in blocker handles most pop-ups effectively. Extensions that claim to block pop-ups better may actually inject their own ads or slow down your browser. Stick with Chrome's default settings unless you have a specific reason to add an extension.
