How to block pop-ups in Safari on iPhone
One switch stops new pop-up windows. The ads and overlays inside a page need a content blocker. Here is how to handle both, and what to do with a fake virus warning.

To block pop-ups in Safari on iPhone, open the Settings app, tap Apps, tap Safari and turn on Block Pop-ups. That stops websites from opening new windows on their own. It does not remove the ads, banners and overlays drawn inside a page, so for those you need a Safari content blocker, which you turn on under Settings, Apps, Safari, Extensions. This guide covers both, plus the built-in way to hide clutter on a single page.
How do I turn on the pop-up blocker in Safari?
Safari's pop-up blocker is a single switch. Apple's instructions for blocking pop-ups in Safari on iPhone are three steps:
- Open Settings. Go to the Settings app on your iPhone.
- Find Safari. Tap Apps, then tap Safari.
- Turn on Block Pop-ups. Turn on the Block Pop-ups switch. Safari now stops pages from opening new windows on their own.
Why do I still see pop-ups with the blocker on?
Because most of what people call pop-ups are not new windows. They fall into three groups, and each needs a different fix:
- New windows and tabs. A page that opens another page by itself. Block Pop-ups stops these.
- Overlays inside the page. Sign-up boxes, cookie notices, video players that follow you down the page, and ads that cover the text. These are part of the page itself, so the pop-up switch never sees them. A content blocker or Distraction Control handles them.
- Fake alerts. Messages that say your iPhone is infected or that you won a prize. These are scams dressed up as system warnings, covered in their own section below.
How do I block ads and overlays in Safari?
Safari supports content blockers: extensions that give Safari a list of rules for what to block on each page. Apple's developer documentation explains that apps tell Safari in advance what kinds of content to block, and that content blockers have no knowledge of your browsing history or the websites you visit. Safari applies the rules itself, so the blocker never sees the page.
To add one, install a content blocker app from the App Store, then turn it on:
- Open the Settings app and tap Apps, then Safari.
- Tap Extensions, then tap the content blocker.
- Turn on Allow Extension. If you use Safari profiles, turn it on for each profile.
You can also do this from Safari: tap the page menu on the left side of the search field, then tap Manage Extensions. Apple's guide to getting extensions for Safari on iPhone covers both paths, and how to turn an extension off for a single website. That last part matters: if a checkout page or a login stops working, turning the blocker off for that site usually fixes it.
A content blocker that is installed but not switched on does nothing, and this is the most common reason people think their ad blocker is broken. Our guide to turning on a Safari ad blocker goes through every switch.
Can I hide one annoying thing on a page without an app?
Yes. In iOS 26, Safari's Distraction Control lets you hide a specific item on a website, such as a banner or a box that covers the article. Apple's steps for hiding distractions when browsing:
- On the website, tap the page menu, then tap Hide Distracting Items.
- Tap the item you want to hide, then tap Hide. Repeat for as many items as you like.
- Close the hide view when you are finished. To bring items back later, open the same menu and tap Show Hidden Items.
Distraction Control works one site at a time and you choose each item by hand. It is a good fix for the one site you read every day, but not for ads across the web.
What should I do about a pop-up that says my iPhone has a virus?
Close the tab and do not tap anything in the message. Apple lists misleading pop-ups and ads that say your device has a security problem among the common scams, along with fake prizes and phony support calls. Never call a phone number from one of these messages, and never enter your Apple Account password on a page it sends you to.
If the page reopens, close every Safari tab that shows it, and turn on Block Pop-ups so it cannot open new windows. If you think you entered a password on a scam page, Apple's advice is to change your Apple Account password immediately and make sure two-factor authentication is on.
Where Clearpage fits
We are making Ad & Popup Blocker: Clearpage, a content blocker for Safari on iPhone that is coming soon to the App Store. We built it around the problem in the previous section: most people cannot tell whether their blocker is actually on.
- Guided setup. It checks each Safari switch, names the one that is still off, and has a button that opens the right place in Settings.
- Proof it is working. A status screen says whether blocking is on right now, which filter lists are loaded and when they were last updated. A test page asks Safari to load ten known ad and tracking addresses and shows how many Safari blocked.
- A way out when a site breaks. Allow a site or pause blocking on it, then turn blocking back on.
The rules come from EasyList and other open filter lists, bundled with the app and refreshed with each release. Blocking, the setup checker, the status screen, the test page, allowed sites and pause are free, with no limits, no account and no VPN. Pro adds site controls in Safari's extension menu, extra filter sets for annoyances, cookie notices and social widgets, and themes, for $4.99 a month or $14.99 once. Clearpage works in Safari only and needs iOS 26.2 or later.
Frequently asked questions
Does Block Pop-ups stop ads in Safari?
No. It stops new windows that a page opens on its own. Ads inside the page need a content blocker, turned on under Settings, Apps, Safari, Extensions.
Will a content blocker work in Chrome or other apps?
No. Safari content blockers apply only in Safari. Other browsers and the ads inside other apps are not affected.
Do Safari content blockers see my browsing?
No. Apple's design has the app hand Safari a list of rules in advance, and Safari applies them. The blocker does not see your history or the sites you visit.
Why did a website stop working after I turned on a blocker?
Some sites need a script or a frame that a filter list also blocks, so a checkout, a login or a video player can stop working. Turn the extension off for that site from the page menu, under Manage Extensions, then reload the page.
