The fastest way to stop pop-ups on Android

Most pop-ups on Android come through your web browser, and the easiest fix is to turn on the built-in pop-up blocker that comes with Chrome, Firefox, Samsung Internet, and most other browsers. This setting is usually on by default, but if pop-ups are still getting through, you may need to check that it hasn't been turned off or adjust which sites you're allowing them on.

The steps differ slightly by browser, but the principle is the same: open your browser settings, find the privacy or site settings section, and look for "Pop-ups and redirects" or similar language. From there you can turn blocking on, add exceptions for sites you trust, or clear data that might be letting pop-ups through.

If pop-ups persist even with the blocker on, the problem is usually one of three things: a site you've accidentally allowed them on, an app pretending to be a browser, or malware. This guide walks you through each.

Key Takeaways

  • Chrome, Firefox, and Samsung Internet all have pop-up blockers built in — check that yours is turned on in Settings > Privacy or Site Settings.
  • If a specific website keeps showing pop-ups, you may have allowed them on that site without realizing it; check your exceptions list and remove the site.
  • Some apps that look like browsers are actually ad networks in disguise; uninstall anything you don't recognize that claims to be a browser.
  • If pop-ups appear even when you're not using a browser, or they show ads for apps you don't use, run a malware scan using Google Play Protect or a dedicated scanner.

Turn on pop-up blocking in Chrome

Chrome blocks pop-ups by default, but if you're seeing them, the setting may have been turned off. Open Chrome and tap the three-line menu icon in the bottom right (or top right, depending on your phone). Go to Settings, then Privacy and security, then Site settings.

Look for "Pop-ups and redirects" and make sure it's set to "Blocked". If it already says "Blocked" but you're still seeing pop-ups on a particular website, scroll down in that same menu to "All sites" and search for the website's name. If it's listed there with pop-ups allowed, tap it and change the setting to "Block".

After you change the setting, close and reopen Chrome completely — don't just close the tab. Then visit the site again to see if the pop-ups are gone.

Turn on pop-up blocking in Firefox

Firefox also blocks pop-ups by default. To check the setting, open Firefox and tap the three-line menu at the bottom. Go to Settings, then Privacy, and look for "Pop-up blocker". Make sure the toggle is turned on (it should show blue).

If pop-ups are still appearing on a specific site, that site may be on your exceptions list. In the same Privacy settings, look for "Exceptions" under the pop-up blocker section. If the website is listed there, tap it and remove it.

Close Firefox completely and reopen it, then try the website again.

Turn on pop-up blocking in Samsung Internet

Samsung Internet is the default browser on Samsung phones. Open it and tap the three-dot menu icon in the bottom right. Go to Settings, then Privacy, and look for "Pop-ups". Make sure it's set to "Block pop-ups".

If a particular site is still showing pop-ups, check the "Pop-up exceptions" list in the same menu. Remove any sites you don't want to allow pop-ups on, then close and reopen the browser.

Check if an app is actually malware disguised as a browser

If pop-ups appear in an app that claims to be a web browser but isn't one of the major ones (Chrome, Firefox, Samsung Internet, Opera, Edge), it may not be a real browser at all. Fake browsers are often just ad networks wrapped in a browser-like interface.

Look at your app drawer and check what browser apps you have installed. If you see anything unfamiliar — especially anything with a generic name like "Web Browser", "Internet", "Fast Browser", or "Super Browser" — uninstall it. These are rarely legitimate.

To uninstall, long-press the app icon and tap "Uninstall", or go to Settings > Apps, find the app, and tap "Uninstall". After you remove it, use only Chrome, Firefox, Samsung Internet, or another major browser you recognize.

Scan for malware if pop-ups appear outside your browser

If pop-ups show up when you're not even using a browser — or if they appear in multiple apps, or if they're advertising things you've never searched for — you likely have malware. The most common source is an app you installed that asked for permission to display over other apps.

First, check which apps have permission to display over other apps. Go to Settings > Apps > Special app access (or Permissions, depending on your phone), and look for "Display over other apps" or "Overlay". Go through the list and uninstall anything you don't recognize or don't use. Even legitimate apps sometimes abuse this permission, so be aggressive here.

Next, run a malware scan. Google Play Protect is built into most Android phones. Go to Settings > Security > Google Play Protect (or search "Play Protect" in Settings), tap "Scan", and let it run. If it finds anything, follow the prompts to remove it.

If Play Protect doesn't find anything but pop-ups continue, download Malwarebytes from the Google Play Store, run a scan, and remove anything it flags. After scanning, restart your phone.

Clear your browser data if pop-ups started suddenly

Sometimes a website you visit can inject code that causes pop-ups to appear even after you leave. Clearing your browser's cache and cookies can stop this. Open your browser, go to Settings, and look for "Clear browsing data" or "Clear cache".

Select "Cookies and site data" and "Cached images and files", then tap "Clear". This will log you out of most websites, so you may need to sign back in to accounts you use regularly. But it often stops pop-ups that started after visiting a particular site.

If pop-ups stop after clearing data, the problem was a malicious cookie or cached file. If they continue, the issue is likely malware or a fake browser app, which the sections above address.

Frequently Asked Questions

Why do some websites still show pop-ups even with the blocker on?

Some websites use pop-ups that are technically not "pop-ups" in the browser's sense — they're just regular windows that open on the page itself. These aren't blocked by the pop-up blocker. You may also have accidentally allowed pop-ups on that specific site. Check your exceptions list and remove the site if it's there.

Can I block pop-ups on just one website?

Yes. If a site you trust needs pop-ups to work (like a banking site that opens documents in new windows), you can allow pop-ups only on that site. In Chrome, go to Settings > Privacy > Site settings > Pop-ups and redirects, tap "Allowed", and add the website. Pop-ups will be blocked everywhere else.

What's the difference between a pop-up and a pop-under?

A pop-under is an ad window that opens behind your current window so you don't see it until you close the browser. Pop-up blockers usually catch these too, but if you're seeing them, check your exceptions list and make sure your blocker is fully on.

Do I need a separate pop-up blocker app?

No. The built-in blockers in Chrome, Firefox, and Samsung Internet are effective for most users. Third-party pop-up blocker apps often ask for excessive permissions and don't work better than what's already built in. Stick with your browser's native blocker.

Why do pop-ups keep coming back after I close them?

If the same pop-ups return repeatedly, you likely have malware or a fake browser app installed. Run a Google Play Protect scan and check your "Display over other apps" permissions. Uninstall anything unfamiliar, then restart your phone.
