The fastest way to stop pop-ups depends on your browser
Most modern browsers block pop-ups automatically, but the setting is sometimes turned off or the blocker misses certain types. You can turn the built-in blocker back on, adjust how strict it is, or add an extension that catches what the browser misses. The steps differ between Chrome, Firefox, Safari, and Edge, but all of them take less than a minute.
Some pop-ups are legitimate — password managers, chat windows, and file uploads need to open in new windows. A good pop-up blocker lets those through while stopping the unwanted ones. If you block everything, you may break features on sites you use regularly.
Key Takeaways
- Chrome, Firefox, Safari, and Edge all have built-in pop-up blockers that are usually on by default, but you can check and strengthen them in Settings.
- Browser blockers stop most pop-ups, but extensions like uBlock Origin or Adblock Plus catch additional ones that slip through.
- Whitelisting specific sites lets legitimate pop-ups work on pages where you need them while blocking everywhere else.
- Some pop-ups are not actually pop-ups — they are overlays or notifications that require different blocking methods.
How to enable pop-up blocking in Chrome
Chrome blocks pop-ups by default, but you can verify the setting is on and adjust how sensitive it is. Click the three-line menu in the top right corner, then select Settings. Go to Privacy and security on the left side, then click Site settings. Find Pop-ups and redirects in the list and click it. The toggle at the top should show Blocked in blue. If it shows Allowed, click the toggle to turn blocking back on.
Below that toggle, you will see a list of sites you have allowed to show pop-ups. If a site is listed there and you no longer want it to show pop-ups, click the trash icon next to its name. You can also add a site to the blocked list by clicking Add next to "Block" and typing the web address.
How to 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 select Settings. Click Privacy & Security on the left. Scroll down to the Permissions section and look for Pop-ups. The checkbox next to "Block pop-up windows" should be checked. If it is not, click it to turn blocking on.
Below that checkbox, you can see a list of sites you have allowed to show pop-ups. Click the Remove All Sites button to clear the list, or select a single site and click Remove to unblock just that one. If you want to add a site to the blocked list, you can do that from the same screen by typing the address and clicking Block.
How to enable pop-up blocking in Safari
Safari blocks pop-ups by default on macOS and iOS. On a Mac, click Safari in the menu bar at the top, then select Settings. Click the Security tab. Make sure the checkbox next to "Block pop-up windows" is checked. On an iPhone or iPad, go to Settings > Safari and toggle Block Pop-ups to the on position (it will turn green).
Safari does not show you a list of allowed sites the way Chrome and Firefox do. If a site needs to show you a pop-up and Safari is blocking it, the address bar will show a small icon. Click that icon and select Allow Pop-ups for This Website to whitelist just that site.
How to enable pop-up blocking in Edge
Microsoft Edge blocks pop-ups by default. To check the setting, click the three-dot menu in the top right corner and select Settings. Click Privacy, search, and services on the left side. Scroll down to Security and click Site settings. Find Pop-ups and redirects and click it. The toggle should show Blocked. If it shows Allowed, click it to turn blocking back on.
You can manage which sites are allowed to show pop-ups in the same menu. Under "Allow", you will see a list of whitelisted sites. Click the trash icon next to any site to remove it from the allowed list.
Using extensions to block more pop-ups
Browser pop-up blockers catch most unwanted windows, but some slip through because they are technically not pop-ups — they are overlays, notifications, or ads that open within the page itself. Extensions like uBlock Origin, Adblock Plus, and AdGuard block these as well.
To add an extension, go to your browser's extension store. In Chrome, click the puzzle piece icon in the top right, then click Manage extensions, then visit the Chrome Web Store. In Firefox, click the menu and select Add-ons and themes, then search the Firefox Add-ons store. Search for the extension by name, click it, and select Add to Chrome or Add to Firefox. The extension will install automatically and start blocking right away.
Most of these extensions work silently in the background. Some show a small icon in your toolbar that tells you how many ads or pop-ups they blocked on the current page. You can click that icon to see details or to temporarily disable blocking on a specific site if something is not working.
Dealing with pop-ups that are not actually pop-ups
Not every unwanted window is a pop-up. Some sites use overlays — large boxes that cover the page and ask you to sign up for a newsletter, download an app, or accept cookies. These are not pop-ups in the technical sense, so your pop-up blocker will not stop them.
The easiest way to close an overlay is to look for an X button, usually in the top right corner of the box. If there is no X, try pressing the Escape key on your keyboard — many overlays are designed to close when you press Escape. If neither works, extensions like Popup Blocker Pro or I don't care about cookies can automatically close or hide these overlays for you.
Some sites also use notification requests — small prompts asking permission to send you notifications. These are not pop-ups either. You can block them by clicking Block or Don't Allow when the prompt appears. If you accidentally allowed notifications and want to turn them off, go back to your browser's site settings (the same place you manage pop-ups) and find Notifications instead.
Frequently Asked Questions
Why am I still seeing pop-ups if my blocker is on?
Some pop-ups are technically not pop-ups — they are overlays or notifications that blockers do not catch. Others come from sites you have whitelisted. Check whether the window has an X button or closes when you press Escape. If it does, it is probably an overlay, not a pop-up, and you may need an additional extension to block it.
Will blocking pop-ups break websites I use?
Most sites work fine with pop-up blocking on. Some sites use pop-ups for legitimate features like password managers, file uploads, or chat windows. If something stops working on a site you trust, you can whitelist just that site in your browser settings so it can show pop-ups while everything else stays blocked.
Do I need an extension if my browser already blocks pop-ups?
No, not unless you are still seeing unwanted windows after turning on your browser's built-in blocker. Most people do not need an extension. If you do see pop-ups that get through, an extension like uBlock Origin will catch additional ones, but start with your browser's native blocker first.
Can I block pop-ups on my phone?
Yes. Safari on iPhone and iPad has a built-in pop-up blocker you can turn on in Settings. Chrome on Android also blocks pop-ups by default. If you want stronger blocking on mobile, you can install extensions in Firefox for Android or use a browser like Brave that has aggressive ad and pop-up blocking built in.
What is the difference between blocking pop-ups and blocking ads?
Pop-up blockers stop new windows from opening. Ad blockers stop ads from loading and displaying on the page itself. You can have one without the other. Most people use both — your browser's pop-up blocker plus an extension like uBlock Origin that blocks ads and catches pop-ups that slip through.
