Safari blocks popups by default on iPhone, and you can turn that off in Settings

Safari's popup blocker is on by default. If a website you trust needs to open popups — like a banking site that opens a security window, or a ticketing site that opens your confirmation in a new tab — you have two choices: turn off the blocker entirely, or let Safari remember that you trust that specific site.

The fastest route is to disable the blocker in Settings. Open Settings on your iPhone, scroll down and tap Safari, then toggle off Block Pop-ups. That's it. Popups will now open on every website you visit.

If you want to keep the blocker on but allow popups from one site, tap the address bar when you visit that site, then tap the popup icon (it looks like a square with an arrow) and choose Allow. Safari will remember that choice for that domain.

Key Takeaways

  • Go to Settings, tap Safari, and toggle off Block Pop-ups to disable the blocker entirely.
  • If you keep the blocker on, you can allow popups from individual sites by tapping the popup icon in the address bar and selecting Allow.
  • Disabling the blocker means all websites can open popups, including ones you don't trust, so only turn it off if you need to.
  • Some websites store your popup preference, so you may need to allow popups each time you visit if you don't disable the blocker globally.

Why Safari blocks popups and what they're used for

Popups were originally designed to show alerts, confirmations, or additional information without leaving the page you're on. A bank might use a popup to show your account details. A store might use one to display your receipt after checkout. But popups also became a tool for ads, scams, and malware, so browsers started blocking them by default.

Safari's blocker stops most popups automatically. But legitimate sites sometimes need popups to work properly. If a site tells you "popups are blocked," it usually means you need to either disable the blocker or tell Safari to trust that site.

Turning off the blocker in Settings

Open the Settings app on your iPhone. Scroll down until you see Safari and tap it. Look for the option labeled Block Pop-ups — it will have a toggle switch next to it. If the toggle is green (on), tap it to turn it off. The toggle will turn gray, and popups will now open on all websites.

This change takes effect immediately. The next time you visit a website with popups, they will open without being blocked. You don't need to close and reopen Safari or restart your phone.

Allowing popups from one website without disabling the blocker

If you want to keep the blocker on for most sites but allow popups from one you trust, Safari can remember that choice. Visit the website, and when you see a popup notification at the top of the screen (or when the site tells you popups are blocked), look for a popup icon in the address bar. It looks like a small square with an arrow pointing out of it.

Tap that icon and select Allow. Safari will remember this choice for that website. The next time you visit, popups from that site will open without being blocked. If you change your mind later, tap the same icon and select Block.

Note that this preference is stored per domain, so allowing popups on example.com does not allow them on other-example.com. You'll need to set the preference separately for each site.

What to watch out for when disabling the blocker

Turning off the popup blocker means every website can open popups, including ones that want to show you ads, trick you into clicking something, or install malware. If you disable the blocker, you're relying on your own judgment to close unwanted popups and avoid clicking on suspicious ones.

Unwanted popups often have a small X button in the corner — tap it to close them. Some popups try to hide the close button or make it hard to find. If a popup seems suspicious or won't close, close Safari entirely by swiping up from the bottom of the screen (on newer iPhones) or double-tapping the home button and swiping up on Safari (on older models), then reopen it.

A safer approach is to leave the blocker on and use the per-site allow method for websites you actually trust. This way, you get the protection of the blocker for most sites while still being able to use popups on the few that need them.

Re-enabling the blocker if you change your mind

If you turn off the blocker and later decide you want it back on, the process is the same. Open Settings, tap Safari, and toggle Block Pop-ups back on. The toggle will turn green again, and Safari will start blocking popups on all websites.

If you allowed popups from specific sites using the per-site method and want to block them again, visit each site, tap the popup icon in the address bar, and select Block. Safari will forget the allow preference and go back to blocking popups from that site.

Other browsers on iPhone and their popup settings

If you use Chrome, Firefox, or Edge on your iPhone instead of Safari, they also have popup blockers. Chrome's blocker is on by default and can be turned off in Settings > Chrome > Block Pop-ups. Firefox's blocker is in Settings > Firefox > Privacy > Block Pop-ups. Edge's blocker is in Settings > Edge > Privacy > Block Pop-ups.

The process is similar across all browsers: find the popup blocker setting in the app's settings menu and toggle it off. Most browsers don't offer a per-site allow option the way Safari does, so you'll need to choose between blocking all popups or allowing all of them.

Frequently Asked Questions

Will disabling the popup blocker slow down my iPhone?

No. The popup blocker doesn't use much processing power, and turning it off won't make Safari faster or slower. The only difference you'll notice is that popups will now open instead of being blocked.

Can I allow popups from one site without allowing them everywhere?

Yes. Tap the popup icon in the address bar when you visit the site and select Allow. Safari will remember that choice for that domain only. Other websites will still have popups blocked unless you allow them individually or disable the blocker entirely.

What if a website says popups are blocked but I don't see a popup icon?

Some websites detect the blocker but don't trigger an actual popup. Try tapping the address bar and looking for a popup icon, or check if there's a button on the page that says "allow popups" or "open in new window." If neither works, the site may need the blocker disabled entirely.

Do I need to disable the blocker to watch videos or use online tools?

Usually not. Most video sites and online tools work fine with the blocker on. If a site tells you popups are blocked and you can't use it, try allowing popups from that site first before disabling the blocker globally.

If I allow popups from a site, will it remember that choice if I clear my Safari history?

It depends on what you clear. If you clear "History and Website Data," Safari will forget the popup preference. If you only clear history, the preference may remain. To be safe, assume the preference will be forgotten if you clear data, and you may need to allow popups again the next time you visit.
