The fastest way to block pop-ups in Chrome

Chrome blocks most pop-ups automatically — you do not have to install anything or change settings. When a site tries to open a pop-up window, Chrome stops it and shows a small notification at the top of the address bar saying "Pop-up blocked." If you want to see that pop-up anyway, click the notification and select "Always allow pop-ups on [website name]."

If pop-ups are still getting through, the problem is usually a browser extension you installed, not Chrome's built-in blocker. Extensions can override Chrome's pop-up filter or inject their own ads. The solution is to find and remove the extension causing the problem, not to install another blocker on top of it.

For the rare cases where Chrome's default blocker is not catching everything, you can tighten the settings or use an extension. But start by checking what extensions you have running — that solves the problem nine times out of ten.

Key Takeaways

  • Chrome blocks pop-ups by default; when one is blocked, you will see a notification in the address bar that lets you allow it for that site if you choose.
  • Most pop-ups that get through come from browser extensions you installed, not from websites themselves.
  • Remove suspicious extensions from your Extensions page (chrome://extensions) — this is faster and more effective than installing a pop-up blocker extension.
  • If you want to allow pop-ups on a specific site you trust, click the blocked pop-up notification and select "Always allow pop-ups on [site]."
  • Chrome's built-in blocker is strong enough for most people; additional extensions usually cause more problems than they solve.

Check which extensions are running and remove the ones you do not recognize

Open a new tab in Chrome and type chrome://extensions into the address bar, then press Enter. This page shows every extension installed on your browser. Look through the list for anything you do not remember installing or anything with a name that sounds like an ad network or toolbar.

Common culprits include extensions with names like "Web Companion," "Shopping Helper," "Price Tracker," or anything that promises to save you money or show you deals. These often come bundled with free software you downloaded, or they were installed by a website you visited. Click the trash icon next to any extension you do not want, then confirm the removal.

After you remove an extension, close all your Chrome tabs and open a new one. Visit a site where you were seeing pop-ups and check whether they have stopped. If pop-ups are still appearing, go back to chrome://extensions and remove another suspicious extension, then test again.

Tighten Chrome's pop-up settings if the default blocker is not enough

Chrome's pop-up blocker is on by default and you cannot turn it off completely — the browser will always block pop-ups unless you explicitly allow them. But you can check that the setting has not been changed. Click the three-line menu in the top right corner of Chrome, select Settings, then click Privacy and security on the left side.

Scroll down to Site settings and click it. Look for Pop-ups and redirects in the list. Click on it and make sure the toggle at the top is set to Blocked. If it says "Allowed," click the toggle to turn it back on.

Below that toggle, you will see a list of sites you have allowed to show pop-ups. Review this list and remove any sites you do not recognize or no longer trust. Click the three dots next to each site and select Remove.

Use an extension only if Chrome's blocker is not catching everything

If you have removed all suspicious extensions and tightened Chrome's settings but pop-ups are still getting through, an additional pop-up blocker extension may help. uBlock Origin is a widely used option that blocks ads and pop-ups without slowing down your browser. AdBlock Plus is another choice, though it allows some ads by default unless you change the settings.

Before you install any extension, read the reviews on the Chrome Web Store and check how many users have it. Extensions with millions of users and mostly positive reviews are safer than new extensions with few reviews. Never install an extension just because a website tells you to — that is usually a sign it is not trustworthy.

After you install an extension, go back to chrome://extensions and make sure it is the only blocker running. Having two pop-up blockers at once can cause problems and slow down your browser. If you install a new blocker and pop-ups get worse instead of better, remove it and go back to Chrome's default settings.

Stop allowing pop-ups on sites you no longer trust

If you once allowed pop-ups on a website and now regret it, you can remove that permission. Go to chrome://settings/content/popups and you will see a list of every site you have allowed to show pop-ups. Click the three dots next to any site and select Remove. The next time you visit that site, Chrome will block its pop-ups again.

You can also manage pop-up permissions directly from the address bar. Click the lock icon or information icon next to the website address, then click Pop-ups and redirects. Change the setting from "Allow" to "Block" and Chrome will remember your choice for that site.

Understand what Chrome considers a pop-up

Chrome blocks windows that open without you clicking on anything. This includes ads that appear in new windows, fake read buttons, and redirect pages. It does not block pop-ups that appear inside the page itself — those are called "pop-unders" or in-page ads, and they are harder to stop because they are technically part of the website's content.

If you see ads appearing inside a webpage rather than in a separate window, those are not pop-ups in the technical sense. Chrome's pop-up blocker cannot stop them. An extension like uBlock Origin can block many of these in-page ads, but some websites will not load properly if you block all ads, so you may need to allow ads on sites you want to support.

Frequently Asked Questions

Why does Chrome say "Pop-up blocked" but I still see ads?

The ads you are seeing are probably not pop-ups — they are ads built into the webpage itself. Chrome's pop-up blocker only stops windows that open without you clicking. In-page ads require an extension like uBlock Origin to block them. Some websites will not load if you block all ads, so you may need to allow ads on sites you trust.

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

Yes. When Chrome blocks a pop-up, click the notification in the address bar and select "Always allow pop-ups on [website name]." To remove that permission later, click the lock or information icon next to the address bar, find Pop-ups and redirects, and change it back to Block.

Is it safe to install a pop-up blocker extension?

Chrome's built-in blocker is strong enough for most people. If you do install an extension, choose one with millions of users and good reviews, like uBlock Origin. Never install an extension a website tells you to install. Remove it when ready if it makes pop-ups worse instead of better.

What if a website I trust needs pop-ups to work?

Some websites use pop-ups for legitimate features like login windows or file downloads. If a site is not working properly, click the pop-up blocked notification and select "Always allow pop-ups on [website name]." Chrome will remember this choice and stop blocking that site's pop-ups.

Do I need to restart Chrome after blocking a pop-up?

No. Chrome blocks pop-ups in real time. If you change a pop-up setting or remove an extension, close all your tabs and open a new one to test whether the change worked. You do not need to restart the entire browser.
