Chrome blocks most pop-ups by default, and you can disable this for specific websites or turn it off entirely
Google Chrome's pop-up blocker stops most unsolicited windows from opening, but it also blocks pop-ups that legitimate websites need to function — things like login windows, document viewers, or payment forms. You can disable blocking for individual sites without turning off protection everywhere, or you can turn off the blocker completely if you prefer to manage pop-ups yourself.
The fastest route depends on what you're trying to do. If a website needs pop-ups to work properly, allow them just for that site. If you want Chrome to stop blocking any pop-ups at all, change the setting in Chrome's privacy controls. Both take less than a minute.
Key Takeaways
- Chrome's pop-up blocker is on by default, and you can allow pop-ups for a single website without changing your overall security settings.
- When Chrome blocks a pop-up, a small notification appears in the address bar — click it to allow pop-ups from that site.
- You can turn off pop-up blocking entirely through Chrome Settings under Privacy and Security, though this leaves you exposed to unwanted windows.
- Websites you allow pop-ups for stay on your list until you remove them, so you only have to allow them once.
- If you change your mind, you can block pop-ups again for any site by removing it from your allowed list.
Allow pop-ups for one website without changing Chrome's overall settings
When Chrome blocks a pop-up, a small icon appears in the address bar on the right side — it looks like a stacked window or a blocked symbol. Click that icon and you'll see a list of the pop-ups Chrome blocked. Select "Always allow pop-ups and redirects from [website name]" and Chrome will stop blocking them for that site only.
The next time you visit that website, pop-ups will open normally. Chrome remembers your choice, so you won't have to allow them again unless you manually remove the site from your list later. This approach keeps your blocker active for every other website while solving the problem for the one site that needs pop-ups to work.
If you don't see the blocked pop-up icon, the website may not have tried to open a pop-up, or your browser may have let it through already. Try the action that should trigger the pop-up — clicking a button, submitting a form, or opening a link — and watch the address bar again.
Turn off Chrome's pop-up blocker completely
Open Chrome and click the three vertical dots in the top right corner. Select "Settings," then choose "Privacy and security" from the left menu. Click "Site settings," then scroll down and select "Pop-ups and redirects."
You'll see two options: "Blocked (recommended)" and "Allowed." The blocker is currently set to "Blocked." Click the toggle or select "Allowed" to turn off pop-up blocking for all websites. Chrome will now let any website open pop-ups without asking you first.
Turning off the blocker entirely means you may see unwanted pop-ups, advertisements, or malicious windows from websites you don't trust. Most people keep the blocker on and allow pop-ups only for sites that need them, rather than disabling it everywhere.
Remove a website from your allowed pop-ups list
If you allowed pop-ups for a website and now want Chrome to block them again, go back to Settings > Privacy and security > Site settings > Pop-ups and redirects. Under the "Allowed" section, you'll see a list of websites you've permitted. Find the site you want to remove and click the trash icon next to it.
Chrome will when ready start blocking pop-ups from that website again. You can remove sites one at a time, or if you want to clear the entire list, click "Clear all" at the top of the allowed sites section. This doesn't turn off the blocker — it just empties your exceptions list.
What to do if a pop-up blocker icon doesn't appear
Sometimes a website tries to open a pop-up but Chrome's blocker doesn't show a notification. This usually means the pop-up was already allowed, the website didn't actually try to open one, or the pop-up was blocked by an extension you installed rather than by Chrome itself.
Check your extensions by clicking the puzzle piece icon in the top right of Chrome, then look for any ad blockers or security tools. Some extensions have their own pop-up blocking features that work separately from Chrome's built-in blocker. You may need to adjust settings in that extension instead, or temporarily disable it to test whether it's the one blocking the pop-up.
If you're still not seeing the pop-up, try the action that should trigger it again — sometimes websites require a specific click or interaction to open a pop-up window.
Understand the difference between pop-ups and pop-unders
Chrome's pop-up blocker stops windows that open on top of the page you're viewing. A pop-under is a window that opens behind your current window, so you don't see it until you minimize or close Chrome. Chrome's blocker doesn't catch pop-unders the same way because they don't interrupt your browsing when ready.
If you're seeing windows appear behind your current browser window, the blocker may not be the issue. These are often blocked by antivirus software or by extensions designed to catch them. Check your extensions first, or consider installing an ad blocker that specifically targets pop-unders if they're a persistent problem.
Frequently Asked Questions
Why does Chrome block pop-ups if some websites need them?
Pop-ups were historically used for advertisements and malicious content, so Chrome blocks them by default to protect you. Legitimate websites that need pop-ups — like banks, document viewers, or video players — can still function if you allow them for that specific site. You get protection by default and control over exceptions.
Will turning off the pop-up blocker affect my security?
Disabling the blocker means you may encounter unwanted or malicious pop-ups from untrusted websites. Most security experts recommend keeping the blocker on and allowing pop-ups only for sites you trust. If you turn it off, monitor your browsing and consider using an extension that catches malicious pop-ups instead.
Can I block pop-ups from one website but allow them from another?
Yes. Keep the blocker on (the default setting) and allow pop-ups only for the websites that need them. Chrome maintains a separate list of allowed sites, so you can have different rules for different websites without changing your overall blocker setting.
What if I accidentally allowed pop-ups and now regret it?
Go to Settings > Privacy and security > Site settings > Pop-ups and redirects and find the website in your "Allowed" list. Click the trash icon next to it to remove it. Chrome will block pop-ups from that site again when ready.
Is there a difference between disabling the blocker and allowing pop-ups for a site?
Yes. Disabling the blocker turns off protection for all websites. Allowing pop-ups for a specific site keeps the blocker active everywhere else. Allowing pop-ups for individual sites is the safer approach because you maintain protection against unwanted pop-ups from sites you don't trust.
