Chrome blocks most pop-ups automatically, and you can turn that off for specific websites or disable it entirely

Chrome's pop-up blocker stops most new windows and tabs from opening without your permission. It works silently in the background — you won't see a settings screen every time it blocks something. If a website you trust needs to open pop-ups to work properly (a login window, a document preview, a payment form), you have two choices: allow pop-ups just for that one site, or turn off the blocker completely. Most of the time, allowing pop-ups for one site is the safer move.

The blocker is on by default because most pop-ups are advertisements, scams, or attempts to collect your data. Legitimate websites rarely depend on pop-ups for core features — they use them for optional things like chat support or document previews. When you allow pop-ups for a specific site, Chrome remembers that choice and lets that site's windows through while still blocking pop-ups everywhere else.

Key Takeaways

  • Chrome blocks pop-ups by default, and you can allow them for a single website without turning off protection everywhere.
  • When a pop-up is blocked, a small icon appears in the address bar — click it to see what was blocked and allow it.
  • You can also go to Chrome Settings, find the Privacy and Security section, and add specific websites to a pop-up allow list.
  • Turning off the blocker entirely leaves you exposed to unwanted pop-ups, ads, and potentially malicious windows on any site you visit.
  • If a site's pop-ups still don't work after you allow them, the problem is usually the site itself, not Chrome's settings.

Allow pop-ups for one website using the address bar icon

When Chrome blocks a pop-up, a small icon appears to the right of the address bar — it looks like a rectangle with a line through it. Click that icon and you'll see a list of blocked pop-ups. At the bottom of that list, click "Always allow pop-ups and redirects from [website name]." Chrome will remember this choice and let that site's pop-ups through from now on.

This is the fastest way if you're already on the site and notice something isn't working. The permission stays in place until you manually remove it, so you won't have to do this every time you visit. If you don't see the icon, it means Chrome hasn't blocked anything on that page yet — the site may not be trying to open pop-ups, or it may be using a different method to open windows that Chrome doesn't classify as pop-ups.

Add a website to the pop-up allow list in Settings

If you want to set up permission before you visit a site, or if you prefer to manage all your pop-up rules in one place, use Chrome Settings. Click the three vertical dots in the top right corner of Chrome, then select Settings. On the left side, you'll see a menu — go to Privacy and Security.

Under Privacy and Security, click Site Settings. Scroll down and select Pop-ups and redirects. Under "Allow," you'll see a list of websites that can send you pop-ups. Click "Add" and type the website address (for example, example.com). Chrome will now allow pop-ups from that site. You can remove a site from this list anytime by clicking the three dots next to its name and selecting Remove.

Turn off the pop-up blocker entirely (not recommended)

If you want to disable the blocker for all websites, go to Settings, then Privacy and Security, then Site Settings, then Pop-ups and redirects. At the top, toggle the switch from "Blocked (recommended)" to "Allowed." This turns off pop-up blocking everywhere.

Disabling the blocker entirely exposes you to unwanted advertisements, fake read buttons, and windows designed to trick you into installing software or giving up personal information. Most security experts recommend keeping the blocker on and allowing pop-ups only for the specific sites that need them. If you turn it off, you're responsible for recognizing and closing suspicious windows yourself — and some of those windows are designed to be hard to close or to look like system warnings.

What to do if pop-ups still don't work after you allow them

Sometimes a website's pop-ups won't open even after you've given Chrome permission. This usually means the problem is with the website's code, not with Chrome's settings. Try these steps: first, refresh the page. Second, clear your browser cache by going to Settings, then Privacy and Security, then Clear Browsing Data, select "All time," and click Clear Data. Third, try the site in an incognito window (Ctrl+Shift+N on Windows, Cmd+Shift+N on Mac), which loads pages without extensions or cached data.

If pop-ups still don't work, contact the website's support team. They may have a known issue, or they may need you to disable a browser extension that's interfering. Chrome extensions can sometimes block pop-ups even when you've told Chrome to allow them. The website's support team can walk you through whether the problem is on their end or yours.

How to tell if an extension is blocking pop-ups

Some browser extensions (ad blockers, privacy tools, password managers) have their own pop-up blocking rules that override Chrome's settings. If you've allowed pop-ups in Chrome but they still don't appear, an extension might be the culprit. Click the puzzle-piece icon in the top right of Chrome to see your installed extensions. Look for any that mention blocking ads, pop-ups, or tracking.

Try temporarily disabling the extension by clicking the toggle next to its name, then reload the website. If pop-ups work now, the extension was blocking them. You can then either remove the extension, adjust its settings, or add the website to that extension's allow list — the process varies by extension, so check the extension's settings page or documentation. Some extensions let you add sites to an allow list the same way Chrome does; others require you to turn them off entirely for that site.

The difference between pop-ups and pop-unders

Chrome's blocker stops both pop-ups (windows that appear on top of the page you're viewing) and pop-unders (windows that open behind your current window). Some websites use pop-unders for legitimate purposes, like opening a support chat in the background. If you allow pop-ups for a site, you're also allowing pop-unders.

If a site is opening too many windows even after you've allowed pop-ups, you may want to remove that site from your allow list and contact the website owner to report the problem. Excessive pop-ups are often a sign of poor web design or, in some cases, a compromised website. Most legitimate sites open only one or two pop-ups per visit; if you're seeing dozens, something is wrong.

Frequently Asked Questions

Why does Chrome block pop-ups in the first place?

Most pop-ups are advertisements or scams designed to distract you, collect your data, or trick you into downloading malware. Chrome's blocker stops these automatically so you don't have to close them manually. Legitimate websites rarely rely on pop-ups for core features — they use them for optional things like chat support or document previews.

If I allow pop-ups for one site, does that affect other sites?

No. Each permission is specific to the website you allow it for. Allowing pop-ups on one site does not change Chrome's behavior on any other site. You can have pop-ups allowed for five websites and blocked everywhere else.

Can I allow pop-ups temporarily and then block them again?

Yes. Go to Settings, Privacy and Security, Site Settings, Pop-ups and redirects, and find the website in the "Allow" list. Click the three dots next to it and select Remove. The site will go back to being blocked when ready.

What if a pop-up looks suspicious even though I allowed it?

Close it. Allowing pop-ups for a site means Chrome won't block them, but you should still treat any pop-up with skepticism. Never enter passwords, credit card numbers, or personal information into a pop-up unless you're certain it came from the website you trust. If a pop-up asks you to read something or update software, close it and go directly to the official website instead.

Does disabling the pop-up blocker make Chrome slower?

No, but it may make your browsing experience feel slower because you'll have more windows to close manually. The blocker itself uses very little processing power. The real cost of disabling it is the time you spend closing unwanted windows and the risk of accidentally clicking on something malicious.
