The fastest way to disable pop-ups depends on what you're using

Most browsers have a built-in pop-up blocker that you can turn on in settings — it blocks most unwanted windows by default, though some still slip through. If pop-ups keep appearing anyway, you can add a browser extension that catches more aggressive ones, adjust your browser's notification settings to stop permission requests, or clear your browser data to remove tracking cookies that trigger targeted ads. Email pop-ups usually come from your email provider's settings or from malware, so the fix is different depending on the source.

The steps below cover the major browsers and email services. If you're seeing pop-ups on a specific website, that site may be using them intentionally — blocking them there won't affect other sites.

Key Takeaways

  • Chrome, Firefox, Safari, and Edge all have pop-up blockers built in, and they are usually turned on already — check your settings to confirm.
  • Browser notifications (the permission requests that appear in the corner) are separate from pop-ups and need their own setting to disable.
  • If your pop-up blocker is on but pop-ups still appear, a browser extension designed to block ads can catch the ones that slip through.
  • Email pop-ups usually come from your email account's settings or from malware on your device, not from your browser.
  • Clearing your browser cache and cookies removes tracking data that advertisers use to target you with pop-ups.

How to turn on pop-up blocking in Chrome, Firefox, Safari, and Edge

Chrome: Open Chrome and select the three vertical dots in the top right corner. Go to Settings, then Privacy and Security, then Site Settings. Scroll down and select Pop-ups and redirects. Make sure "Blocked (recommended)" is selected. If a specific site needs to show pop-ups, you can add it to the "Allow" list on this same page.

Firefox: Open Firefox and select the three horizontal lines in the top right. Go to Settings, then Privacy & Security. Under Permissions, find the "Pop-ups" section and check the box next to "Block pop-up windows." You can add exceptions for sites that need pop-ups by selecting "Exceptions" on the same screen.

Safari: Open Safari and select Safari in the menu bar at the top of your screen. Go to Settings (or Preferences on older Macs), then the Security tab. Check the box next to "Block pop-up windows." This setting applies to all websites unless you add exceptions.

Edge: Open Edge and select the three horizontal dots in the top right. Go to Settings, then Privacy, Search, and Services. Under Site Permissions, select Pop-ups and redirects. Make sure the toggle is set to "Block."

Stopping browser notifications and permission requests

Browser notifications are different from pop-ups — they appear as small boxes in the corner of your screen and ask permission to send you alerts. Websites request this permission when you visit them. Blocking notifications stops these requests from appearing.

Chrome: Go to Settings > Privacy and Security > Site Settings > Notifications. Toggle off "Sites can ask to send notifications." If you want to block notifications from a specific site you've already allowed, find that site in the "Allow" list and remove it.

Firefox: Go to Settings > Privacy & Security > Permissions > Notifications. Check the box next to "Block new requests asking to allow notifications."

Safari: Go to Settings > Websites > Notifications. Select "Deny" in the dropdown menu for "When visiting other websites."

Edge: Go to Settings > Privacy, Search, and Services > Site Permissions > Notifications. Toggle off "Ask before sending."

Using browser extensions to block more aggressive pop-ups

If your browser's built-in blocker isn't catching everything, a third-party extension can help. Popular options include uBlock Origin, Adblock Plus, and AdGuard — all are free and work across most websites. These extensions block ads and pop-ups more aggressively than your browser's default settings.

To add an extension in Chrome or Edge, go to the Chrome Web Store or Microsoft Edge Add-ons, search for the extension name, and select "Add to Chrome" or "Add to Edge." For Firefox, go to the Firefox Add-ons page and select "Add to Firefox." For Safari, extensions are available through the App Store — search for the extension name and install it like any other app.

Keep in mind that some websites detect ad blockers and may ask you to disable them to view content. You can usually add those sites to your extension's whitelist if you want to see their content without blocking.

Clearing cookies and cached data to reduce targeted pop-ups

Advertisers use tracking cookies to follow you across websites and show you targeted pop-ups based on your browsing history. Clearing your cache and cookies removes this tracking data and can reduce the number of personalized pop-ups you see.

Chrome: Select the three vertical dots, go to More Tools > Clear Browsing Data. Select "All time" from the dropdown, check "Cookies and other site data" and "Cached images and files," then select "Clear data."

Firefox: Select the three horizontal lines, go to Settings > Privacy & Security. Under Cookies and Site Data, select "Clear Data." Check both boxes and select "Clear."

Safari: Select Safari in the menu bar, go to Settings, then the Privacy tab. Select "Manage Website Data," then "Remove All," and confirm.

Edge: Select the three horizontal dots, go to Settings > Privacy, Search, and Services. Under Clear Browsing Data, select "Choose what to clear." Select "All time," check "Cookies and other site data" and "Cached images and files," then select "Clear now."

Dealing with pop-ups in email

Pop-ups in your email inbox usually come from one of two sources: your email provider's settings or malware on your device. If you're seeing pop-ups when you open Gmail, Outlook, or Yahoo Mail, check your email settings first. If they appear even when you're not in email, the issue is likely malware.

Gmail: Open Gmail and select the gear icon in the top right. Go to Settings > General. Scroll down to "Images" and make sure "Ask before displaying external images" is selected. This prevents some ads from loading automatically. You can also enable "Block all images" if you prefer, though this will hide images in legitimate emails too.

Outlook: Open Outlook and select Settings (the gear icon). Go to Mail > Junk Email. Make sure the filter is set to "Standard" or "Strict" to block more unwanted messages and ads.

Yahoo Mail: Open Yahoo Mail and select the gear icon. Go to Settings > General. Look for "Pop-up Blocker" and make sure it is enabled.

If pop-ups continue after checking your email settings, run a malware scan using Windows Defender (on Windows) or Malwarebytes (on Mac or Windows). Malware can inject pop-ups into your browser and email even when your settings are correct.

What to do if a website forces pop-ups you can't close

Some websites use pop-ups that don't have a visible close button or that reopen immediately after you close them. These are usually ads designed to be difficult to dismiss. You have a few options: refresh the page and close the pop-up before it fully loads, use your browser's back button to leave the site, or add the site to your ad blocker's blacklist so it blocks all pop-ups there.

If a pop-up asks you to download something or enter personal information, do not do it — close the pop-up by pressing Escape on your keyboard or by closing the browser tab entirely. Legitimate websites do not require you to interact with pop-ups to view their content.

Frequently Asked Questions

Why do pop-ups still appear if my blocker is turned on?

Some pop-ups are designed to bypass built-in blockers, especially on sites that rely on ad revenue. Adding a browser extension like uBlock Origin or Adblock Plus catches most of these. If pop-ups appear only on one specific site, that site may be whitelisted in your blocker settings — you can remove it from the allow list.

Can I block pop-ups on just one website?

Yes. In Chrome, Firefox, Safari, and Edge, you can add specific sites to your pop-up blocker's exception list so they can show pop-ups while other sites are blocked. Go to your browser's pop-up settings and look for "Allow" or "Exceptions" to add a site. You can also use an ad blocker extension to block pop-ups on specific sites while allowing them elsewhere.

Is it safe to use ad blocker extensions?

Yes, extensions from official stores like the Chrome Web Store and Firefox Add-ons are safe. Stick to well-known options like uBlock Origin, Adblock Plus, or AdGuard. Avoid extensions from unknown sources or that ask for unusual permissions. Some websites detect ad blockers and may ask you to disable them — you can usually add those sites to your extension's whitelist instead.

What if I see pop-ups even when I'm not browsing?

Pop-ups appearing outside your browser usually indicate malware on your device. Run a full scan with Windows Defender (Windows) or Malwarebytes (Mac or Windows). Restart your device after the scan completes. If pop-ups continue, check your browser extensions — remove any you don't recognize or didn't intentionally install.

Do I need to clear my cookies regularly to stop pop-ups?

Clearing cookies once reduces targeted pop-ups, but advertisers will start tracking you again as you browse. If you want ongoing protection, enable your browser's privacy mode or use a browser extension that blocks tracking cookies automatically. Chrome's Privacy Sandbox and Firefox's Enhanced Tracking Protection both reduce tracking without requiring manual clearing.
