Chrome blocks most pop-ups automatically — check your settings first

Chrome comes with a built-in pop-up blocker that is turned on by default. Most unwanted pop-ups never reach your screen because of this. If you are still seeing pop-ups, the blocker may have been turned off, or a website you have allowed may be sending them. Before installing anything new, open Chrome's settings and confirm the blocker is active, then review which sites have permission to show pop-ups.

The fastest way to check is to click the three vertical dots in the top right corner of Chrome, select Settings, then go to Privacy and security on the left side. Look for Site settings, then Pop-ups and redirects. If it says "Blocked" in blue, your blocker is on. If it says "Allowed", turn it back on by clicking the toggle.

Key Takeaways

  • Chrome's built-in pop-up blocker is on by default and stops most unwanted pop-ups without any action from you.
  • If pop-ups are getting through, check Settings > Privacy and security > Site settings > Pop-ups and redirects to confirm the blocker is enabled.
  • Websites you have allowed to show notifications or pop-ups will bypass the blocker, so review your allowed sites list and remove ones you no longer trust.
  • If a pop-up appears, you can block that site when ready by clicking the pop-up blocker icon in the address bar.
  • Extensions that block ads and trackers can stop additional pop-ups that slip past Chrome's built-in blocker, though they are optional.

Review which websites have permission to send pop-ups

When you visit a website, it can ask for permission to show pop-ups, notifications, or other content. You may have said yes to some of these requests without realizing what you were allowing. These allowed sites will bypass Chrome's pop-up blocker. Go to Settings > Privacy and security > Site settings > Pop-ups and redirects, then scroll down to the "Allowed" section. This list shows every site that has permission to send pop-ups to you.

Look through the list and remove any sites you do not recognize or no longer want pop-ups from. Click the three dots next to each site name and select Remove. If a site you trust is sending unwanted pop-ups, removing it from this list will stop them. You can always allow the site again later if it needs to show you something important, like a login code or a shipping notification.

Block pop-ups from a specific site right away

When a pop-up appears on your screen, Chrome usually shows a small icon in the address bar — it looks like a box with a line through it. Click that icon and select "Block pop-ups from [site name]" to stop that website from sending more. This adds the site to your blocked list when ready, and you do not have to dig through settings.

If you do not see the icon, the pop-up may have come from a different source, like an ad network or a redirect. In that case, close the pop-up by clicking the X button, and if the same pop-up keeps appearing, go to Settings > Privacy and security > Site settings > Pop-ups and redirects and add the site to your blocked list manually by clicking "Add" next to "Not allowed".

Use extensions to block additional pop-ups and ads

Chrome's built-in blocker stops most pop-ups, but some websites use tricks to get around it. Ad-blocking extensions like uBlock Origin, Adblock Plus, or Ghostery can catch pop-ups that slip through, along with blocking ads and tracking scripts. These are optional — you do not need them if Chrome's blocker is working well for you — but they offer extra protection if you visit sites known for aggressive pop-ups.

To add an extension, go to the Chrome Web Store, search for the extension by name, and click "Add to Chrome". The extension will appear as an icon in your toolbar. Most ad blockers work in the background without any setup. Some let you click their icon to see what they blocked on the current page, which can help you understand what is happening behind the scenes.

Turn off notifications if websites are sending pop-up alerts

Notifications are different from pop-ups, but they look similar and can be just as annoying. A website can ask permission to send you notifications — these appear as small boxes in the corner of your screen or on your desktop. If you are seeing these alerts, go to Settings > Privacy and security > Site settings > Notifications. Look at the "Allowed" list and remove any sites you do not want notifications from.

You can also block notifications from a site as soon as it asks. When a website requests permission to send notifications, a prompt appears at the top of the page. Click "Block" instead of "Allow", and that site will never ask again. If you accidentally allowed a site, removing it from the notifications list will stop the alerts.

Clear your browsing data if pop-ups started suddenly

If pop-ups appeared suddenly after visiting a new website, malicious code or cookies from that site may be causing them. Clearing your browsing data can remove this code. Go to Settings, click Privacy and security, then select Clear browsing data. Choose the time range "All time" and make sure Cookies and cached images are checked. Click Clear data, then restart Chrome.

If the pop-ups stop after clearing data, you know the problem came from a website you visited. If they continue, the issue is likely a browser extension or a site that has permission to send pop-ups. Check your extensions by clicking the puzzle piece icon in the top right corner and looking for anything unfamiliar — if you do not recognize an extension, click the three dots next to it and select Remove from Chrome.

Disable extensions that may be causing pop-ups

Sometimes an extension you installed is the source of pop-ups, even if it claims to block them. Malicious or poorly made extensions can inject ads and pop-ups into every page you visit. To learn about an extension is the problem, turn them off one at a time and see if the pop-ups stop. Click the puzzle piece icon in the top right, find the extension, click the three dots, and select Disable. Wait a few minutes and visit a few websites to see if pop-ups still appear.

If disabling an extension stops the pop-ups, remove it permanently by clicking the three dots again and selecting Remove from Chrome. If you need that extension, look for an updated version or find a different one that does the same job. Stick with extensions from well-known developers — check the reviews and the number of users before you install anything new.

Frequently Asked Questions

Why am I still seeing pop-ups if Chrome's blocker is on?

The most common reason is that you allowed a specific website to show pop-ups. Check Settings > Privacy and security > Site settings > Pop-ups and redirects and look at your "Allowed" list. Remove any sites you do not recognize. Pop-ups can also come from extensions you installed, so check your extensions list and disable anything unfamiliar.

Can I block pop-ups from one website but allow them from another?

Yes. Go to Settings > Privacy and security > Site settings > Pop-ups and redirects. You can add specific sites to your "Allowed" list if they need to show you important pop-ups, like login codes or shipping updates. All other sites will be blocked. Click "Add" next to "Not allowed" to block a specific site even if your blocker is off.

Do I need an ad blocker extension if Chrome already blocks pop-ups?

No, you do not need one. Chrome's built-in blocker handles most pop-ups. Extensions are optional and useful only if you visit sites that use advanced tricks to bypass Chrome's blocker, or if you want to block ads and tracking scripts in addition to pop-ups.

What should I do if a pop-up asks for my password or personal information?

Close it when ready. Legitimate websites do not ask for passwords or credit card numbers in pop-ups. This is a common scam. Close the pop-up by clicking the X, then block that site from showing pop-ups again. If you are worried the pop-up came from the website itself, close the entire tab and visit the site fresh from your bookmarks or a new search.
