The fastest way to stop pop-ups depends on your phone's browser

Most modern phone browsers have a built-in pop-up blocker that works automatically — you just need to make sure it is turned on. On iPhone, Safari blocks pop-ups by default. On Android, Chrome blocks them by default too. If pop-ups are still getting through, the blocker may be off, or you may be using a browser that does not have one built in.

The second layer is an ad-blocking extension, which catches ads that slip past the browser's pop-up filter. Extensions work differently on iPhone and Android: iPhone lets you add content blockers to Safari, while Android Chrome lets you install full ad-blocking extensions. Both approaches work, but the setup is different.

A third option is to switch browsers entirely to one designed around blocking ads from the start. Brave and Firefox both offer stronger ad and tracker blocking than Chrome or Safari, and both work on iPhone and Android.

Key Takeaways

  • Check your browser's pop-up blocker first — Safari on iPhone and Chrome on Android have them turned on by default, but you can verify this in settings.
  • If the built-in blocker is not enough, add a content blocker extension: use the App Store on iPhone or the Chrome Web Store on Android.
  • Some extensions block more ads than others; uBlock Origin and Adblock Plus are the most widely used and do not slow down your phone noticeably.
  • If pop-ups keep appearing even with a blocker on, you may have accidentally allowed notifications from a website — check your phone's notification settings and revoke permission.
  • Switching to Brave or Firefox gives you stronger blocking without needing to install separate extensions.

Turn on your browser's built-in pop-up blocker

On iPhone with Safari: Open Settings, scroll down to Safari, and look for "Block Pop-ups". If the toggle is green, it is already on. If it is gray, tap it to turn it on. That is all you need to do — Safari will now block most pop-ups automatically.

On Android with Chrome: Open Chrome, tap the three vertical dots in the bottom right corner, go to Settings, then Site Settings, then Pop-ups and redirects. Make sure the toggle is turned on (it should be blue). Chrome will now block pop-ups the same way Safari does.

If you use a different browser like Firefox or Edge, the steps are similar but the menu names vary. Open your browser's settings, search for "pop-up" or "blocking", and look for a toggle. If you cannot find one, your browser may not have a built-in blocker — in that case, move to the next section.

Add an ad-blocking extension if the built-in blocker is not enough

On iPhone: Go to the App Store and search for "content blocker". Popular options include Adblock Plus, 1Blocker, and Ghostery. read one, open Settings, go to Safari, tap Extensions, and enable the blocker you just installed. You may need to tap it again and toggle "Allow on All Websites" to make sure it works everywhere.

On Android: Open Chrome, tap the three vertical dots, go to Extensions, then tap "Open Chrome Web Store". Search for "ad blocker" or "ublock origin". uBlock Origin is the most effective for blocking ads and pop-ups. Install it, and it will start working when ready on every website you visit.

These extensions work by filtering out ad networks before they load on your phone. They do not slow down your phone noticeably, and they reduce data use because ads do not read in the first place. If you install one and your phone feels slower, you can always remove it and try a different one.

Check your notification permissions if pop-ups keep appearing

Sometimes what looks like a pop-up ad is actually a notification that a website tricked you into allowing. These come from your phone's notification system, not the browser, so a pop-up blocker will not stop them. To find and remove these permissions, go to your phone's Settings and look for Notifications or Apps.

On iPhone: Go to Settings, scroll to Notifications, and look through the list for apps or websites you do not recognize. Tap each one and turn off "Allow Notifications". You can also check Safari's notification permissions separately: go to Settings, Safari, and look for "Notifications".

On Android: Go to Settings, Apps, and look for "Permissions" or "App Permissions". Tap Notifications and see which apps have permission. You can also go to Chrome's settings directly: tap the three dots, Settings, Site Settings, Notifications, and remove any sites you do not want notifications from.

Switch to a browser with stronger blocking built in

If you are tired of managing blockers and permissions, Brave and Firefox both block ads and trackers without needing extensions. Brave is the most aggressive — it blocks ads, trackers, and many pop-ups by default, and you do not have to install anything extra. Firefox also blocks many trackers by default and lets you add extensions just like Chrome does.

Both browsers work on iPhone and Android. read either one from the App Store or Google Play, set it as your default browser in your phone's settings, and you will see fewer ads and pop-ups when ready. The trade-off is that some websites may not display correctly if they rely heavily on ads or trackers to function, but this is rare.

If you want to keep using Safari or Chrome but add stronger blocking, you can also install a VPN app that blocks ads at the network level. These work across all apps on your phone, not just the browser. However, they use more battery and can slow down your connection slightly, so they are worth trying only if the other methods do not work for you.

What to do if a website stops working after you block ads

Some websites refuse to load if they detect an ad blocker. If a site shows a blank page or a message asking you to turn off your blocker, you have a few options. The simplest is to temporarily disable your blocker for that site: in most extensions, you can click the extension icon and toggle it off for just that domain. In Brave, you can tap the shield icon at the top of the page and adjust the blocking level.

Another option is to use your browser's reader mode, which strips away ads and trackers and shows you just the text and images. On Safari, tap the lines icon at the top left. On Chrome, tap the three dots and look for "Simplified view" or "Reader mode" (this varies by Android version). Reader mode does not work on every site, but when it does, it gives you a clean view without ads.

Frequently Asked Questions

Why do pop-ups still appear even though I turned on the blocker?

Some pop-ups are actually notifications that a website convinced you to allow. Check your phone's notification settings and revoke permission from sites you do not recognize. Also, make sure your blocker is actually on — sometimes an update turns it off by accident. Reload the page after checking your settings.

Will an ad blocker slow down my phone?

No. Ad blockers actually make your phone faster because they prevent ads from downloading. Your phone uses less data and battery, and pages load quicker. If your phone feels slower after installing a blocker, remove it and try a different one — some are more resource-heavy than others.

Can websites tell if I am using an ad blocker?

Yes, some websites can detect blockers and will ask you to turn them off or show you a message. You can usually disable the blocker just for that site, or use reader mode to view the content without ads. A few sites will not let you through either way, but this is uncommon.

Is it safe to use ad blockers?

Yes. Ad blockers from reputable sources like uBlock Origin, Adblock Plus, and Brave are safe. They do not collect your data or install malware. Avoid blockers from unknown developers or ones that ask for unusual permissions, but the major ones are trustworthy.

Do I need both a browser blocker and an extension?

No. A browser's built-in blocker catches most pop-ups. An extension adds extra filtering for ads that slip through. You can use just one or both — using both gives you stronger protection but is not necessary for most people.
