You enable Chrome’s pop-up blocker from the Pop-ups and redirects setting in the browser’s Privacy and security menu, where you can set the default block for all sites or manage exceptions per site.
Pop-ups interrupt reading, hijack tabs, and sometimes lead to sites you never meant to visit. One wrong click and a reservation tab turns into a “Your PC has a virus!” window that won’t close. Chrome’s built-in blocker stops most of them before they load, and turning it on takes about thirty seconds. The exact menu depends on whether you are using a desktop computer or an Android phone — the paths are slightly different, but neither one is hard to find.
Enabling the Pop-Up Blocker on Desktop Chrome
Desktop Chrome uses a toggle-like setting where you pick the default behavior for every site. The option lives under the Privacy and security section, not in an old Advanced or Content settings menu — if a guide sends you to “Show advanced settings,” it is using a path Chrome dropped years ago.
Here is the current sequence:
- Open Chrome and click the three-dot menu in the top-right corner of the window.
- Select Settings from the dropdown.
- In the left sidebar, click Privacy and security.
- Click Site settings.
- Scroll down and click Pop-ups and redirects.
- Under “Default behavior,” select Don’t allow sites to send pop-ups or use redirects.
Once this is set, Chrome blocks pop-ups and redirects on every site by default. The same page also shows any exceptions you have granted in the past under “Allowed to send pop-ups and use redirects.”
Turning It On for Android
Chrome for Android uses a different layout — there is no sidebar, and the setting is worded as a toggle rather than a choice between blocking and allowing. Google’s own Android support page says to turn the Pop-ups and redirects setting off to block pop-ups, which can be confusing because “off” is the blocking state.
- Open Chrome on your Android device and tap the three-dot menu.
- Tap Settings.
- Tap Site settings.
- Tap Pop-ups and redirects.
- Tap the toggle so that Pop-ups and redirects is turned off.
When the toggle is off, Android Chrome blocks pop-ups. When it is on, pop-ups are allowed. This is the opposite of what many people expect, so the rule to remember is: toggle off to block.
Allowing Pop-Ups for a Specific Site
Some legitimate tools — banking portals, school logins, ticket vendors — require a pop-up to function. Blocking everything would break those sites. Chrome handles this through the exception list on the Pop-ups and redirects settings page.
To add a site exception on desktop:
- On the Pop-ups and redirects settings page, look for the section labeled Allowed to send pop-ups and use redirects.
- Click the Add button next to it.
- Enter the site’s URL. The pattern
[*.]example.comcovers all subdomains — for instance,[*.]google.comincludes mail.google.com and drive.google.com. - Click Add.
On Android, you can add a site exception by tapping Add site exception on the same Pop-ups and redirects page and entering the URL. Be selective — each allowed site is a door that pop-ups can walk through.
What to Do When a Blocked Pop-Up Still Appears
| Situation | What You See | What to Do |
|---|---|---|
| One pop-up was blocked | Chrome shows a small pop-up icon in the address bar on desktop (a window with an X) | Click the icon, then choose “Always allow pop-ups and redirects from [site]” or just allow this one time |
| Multiple pop-ups from the same site | The site loads new windows despite the blocker being on | Check your exception list: the site may already be in “Allowed.” Remove it unless you need it |
| A site that needs pop-ups doesn’t work | The site’s feature (a file download, login pop-up, payment window) never appears | Check whether Chrome blocked it using the address bar icon, then add the site to your allowed exceptions |
| Pop-ups appear after a Chrome update | Your settings look correct but windows still open | Reset the “Pop-ups and redirects” setting to block by default, then re-add only trusted exceptions |
| An extension is causing pop-ups | Pop-ups appear even on sites you do not browse | Open Chrome menu → Extensions → Manage extensions, then disable suspicious add-ons one at a time |
| The blocker seems broken | Pop-ups appear constantly across all sites | Make sure you selected “Don’t allow sites to send pop-ups or use redirects” on desktop, or the toggle is off on Android |
Managing Exceptions from the Address Bar
You do not always need to dig into settings to handle a pop-up. When Chrome blocks a pop-up on desktop, a small icon appears at the right end of the address bar — it looks like a window with a red X. Clicking it shows the site that tried to open the pop-up and two options: allow the pop-up this one time, or always allow pop-ups and redirects from that site. This trick is faster than hunting through the settings menu, and it works even if the pop-up was triggered by a button you clicked on the page.
What This Blocker Cannot Do
Chrome’s built-in pop-up blocker is good, not perfect. It stops most windows that open automatically or when a page loads. It does not stop pop-ups that appear after you deliberately click something labeled “Download” or “Play” — those are triggered by your action, and Chrome treats them as intentional. It also cannot prevent in-page overlays that look like pop-ups but are actually HTML elements inside the same tab; those are site design, not browser windows, and the blocker was never meant to catch them. For in-page overlays, an extension may help, but Chrome’s built-in tool does the heavy lifting for the kind of pop-ups that interrupt and annoy.
Finishing Pop-Up Protection the Right Way
Once you set the desktop option to “Don’t allow sites to send pop-ups or use redirects,” or turn the Android toggle off, the blocker runs automatically in the background. The only risk is adding too many exceptions — each allowed site can send pop-ups freely, so keep the allowed list short. A site that misbehaves once might do it again, and removing an exception is easier than chasing a pop-up from a site you have since forgotten about.
| Checklist Item | Where to Check | Typical Mistake to Avoid |
|---|---|---|
| Default behavior set to block | Settings → Privacy and security → Site settings → Pop-ups and redirects | Leaving it on “Allow” and wondering why pop-ups show up |
| Android toggle is off | Chrome menu → Settings → Site settings → Pop-ups and redirects | Assuming “off” means disabled; off means blocking is active |
| Exception list is short | Under “Allowed to send pop-ups and use redirects” on desktop, or “Allow exceptions” on Android | Adding every site that asks, then getting pop-ups from those sites |
| Address-bar icon is visible | Appears in the address bar when a pop-up is blocked | Missing it because you did not look for the small X icon |
| Suspicious extensions removed | Chrome menu → Extensions → Manage extensions | Assuming pop-ups are always Chrome’s fault when an extension may cause them |
| Browser is up to date | Chrome menu → Help → About Google Chrome | Ignoring updates that may include security fixes for pop-up vectors |
One pass through these checks and the blocker is set for good. If a legitimate site ever fails to load a pop-up you need, use the address-bar icon to allow it — you will see exactly which site is asking, and you will know whether to trust it before you click.
