The fastest way to block pop-ups depends on your browser

Most modern browsers have a built-in pop-up blocker that works automatically — you do not have to turn it on or change settings. Chrome, Firefox, Safari, and Edge all block most pop-ups by default. If pop-ups are still getting through, your blocker may be turned off, or you may need to add a browser extension for stronger filtering.

The steps differ slightly between browsers, but the principle is the same: you either enable the blocker in settings, add an extension from your browser's store, or both. Some pop-ups are harder to stop than others — particularly those that appear when you click a link or button on a website — so you may need more than one method.

Key Takeaways

  • Chrome, Firefox, Safari, and Edge block most pop-ups automatically, but you can check your settings to confirm the blocker is on.
  • If the built-in blocker is not enough, extensions like uBlock Origin, Adblock Plus, and Pop-Up Blocker for Chrome add extra filtering without slowing your browser.
  • Some pop-ups appear when you click a link or button and cannot be blocked by the browser alone — these require an extension.
  • Whitelisting a website in your pop-up blocker lets legitimate pop-ups through on sites you trust, like banking or email services.

Enable pop-up blocking in Chrome

Chrome blocks pop-ups by default, but you can confirm the setting is on and see which sites have been blocked. Click the three-line menu in the top right corner, then select Settings. On the left sidebar, click Privacy and security, then Site settings. Scroll down and click Pop-ups and redirects. Make sure the toggle next to "Blocked (recommended)" is turned on.

If you want to see which sites have tried to show you pop-ups, that same page lists them under "Blocked". You can also add specific websites to the "Allowed" list if a site you trust needs to show pop-ups — for example, some banking sites use pop-ups for security alerts. Click Add next to "Allowed" and type the website address.

Enable pop-up blocking in Firefox

Firefox also blocks pop-ups by default. To check or change the setting, click the three-line menu in the top right, then Settings. On the left sidebar, click Privacy & Security. Under the "Permissions" section, find Pop-ups and make sure the checkbox next to "Block pop-up windows" is checked.

If you need to allow pop-ups on a specific website, you can add it to the exceptions list without turning off blocking everywhere. On the same "Pop-ups" line, click Exceptions. Type the website address and click Allow, then Save Changes. The next time you visit that site, pop-ups will appear normally.

Enable pop-up blocking in Safari and Edge

Safari blocks pop-ups by default and does not have a separate settings page for it — the blocker is always on. If you want to allow pop-ups on a specific website, click Safari in the menu bar, then Settings. Click the Websites tab, then Pop-ups on the left. Find the website in the list and change its setting from "Block" to "Allow".

Edge also blocks pop-ups by default. To adjust settings, click the three-dot menu in the top right, then Settings. Click Privacy, search, and services on the left. Scroll down to "Tracking prevention" and look for Block pop-ups — make sure it is turned on. You can add exceptions the same way: click Manage exceptions and type the website address.

Add a pop-up blocker extension for extra protection

If your browser's built-in blocker is not stopping all pop-ups, an extension can catch more. uBlock Origin is free and blocks pop-ups, ads, and tracking scripts without slowing your browser down. Adblock Plus and Pop-Up Blocker for Chrome are also popular choices. All three are available in the Chrome Web Store, Firefox Add-ons, and Edge Add-ons.

To install an extension, open your browser's store (Chrome Web Store, Firefox Add-ons, or Edge Add-ons), search for the extension name, and click Add to Chrome, Add to Firefox, or Add to Edge. The extension starts working immediately. Most extensions show a small icon in your toolbar — you can click it to see how many pop-ups were blocked on the current page or to adjust settings.

Extensions do not interfere with each other, so you can run your browser's built-in blocker and an extension at the same time. However, running multiple heavy extensions can slow your browser, so start with one and add another only if you still see pop-ups.

Handle pop-ups that appear when you click a link

Some pop-ups open when you click a button or link on a website, not automatically. These are harder to block because the browser cannot tell them apart from legitimate windows the website is supposed to open. An extension like uBlock Origin or Adblock Plus can filter these, but it may also block windows you actually want.

If you encounter a pop-up that keeps appearing on a specific website, right-click on the pop-up window and select Inspect or Inspect Element (the exact wording depends on your browser). This opens the browser's developer tools and shows the code behind the pop-up. You can then report the website to your extension's developers, or switch to a different extension that handles that type of pop-up better.

The simplest approach is to avoid clicking suspicious links or buttons on unfamiliar websites. Pop-ups often appear when you click "Download now", "Claim your prize", or "Click here" on sites that look like they are offering something free. Closing the tab or window is usually faster than trying to block the pop-up after it appears.

Whitelist websites that need pop-ups

Some legitimate websites use pop-ups for important functions — your bank may use them for security alerts, or a video site may use them to display content. If you block pop-ups everywhere, these sites will not work properly. Most browsers and extensions let you create a whitelist of websites where pop-ups are allowed.

In Chrome, Firefox, Safari, or Edge, you can add a website to the exceptions list in your pop-up blocker settings (see the sections above for each browser). If you are using an extension, click its icon in your toolbar and look for an option to disable blocking on the current site. Some extensions show a button that says "Disable on this site" or "Whitelist this domain". Click it, and pop-ups will appear normally the next time you visit.

Frequently Asked Questions

Why am I still seeing pop-ups if my blocker is on?

Some pop-ups are designed to look like system warnings or browser notifications, and they slip past blockers because they do not behave like traditional pop-ups. Others appear when you click a link or button, which the browser cannot block without also blocking legitimate windows. Adding an extension usually stops these, but you may need to try a different one if the first does not work.

Will a pop-up blocker slow down my browser?

Your browser's built-in blocker has almost no impact on speed. Extensions can slow your browser if you run too many at once, but a single well-made extension like uBlock Origin uses very little memory. If your browser feels slow after adding an extension, try disabling it temporarily to see if that is the cause.

Can I block pop-ups on my phone?

Chrome for Android and Safari for iPhone both block pop-ups by default. Firefox for mobile also has a pop-up blocker you can turn on in settings. Extensions are not available on mobile browsers, so you are limited to the built-in blocker, but it catches most pop-ups.

What if a website says I need to disable my pop-up blocker?

Some websites ask you to turn off your blocker so they can show you content or ads. You do not have to disable it everywhere — instead, add that specific website to your blocker's whitelist or exceptions list. This lets pop-ups through only on that site, and your blocker stays on for all others.

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

Extensions from official stores like the Chrome Web Store, Firefox Add-ons, and Edge Add-ons are reviewed before they are published, so they are generally safe. Stick to well-known extensions like uBlock Origin, Adblock Plus, or Pop-Up Blocker for Chrome. Avoid extensions from unknown developers or third-party websites, as they may contain malware or track your browsing.
