How to Disable a Safari Extension on an iPhone

To disable a Safari extension on iPhone, open the Settings app, tap Apps > Safari > Extensions, tap the extension, and turn off Allow Extension. You can turn it back on the same way at any time, or switch it off for just one website from inside Safari.

This guide covers turning an extension off everywhere, turning it off for a single site, how extensions behave in Private Browsing, and removing an extension completely. It follows Apple’s Get extensions to customize Safari on iPhone and Browse the web privately in Safari on iPhone guides for current iOS.

How to Turn Off a Safari Extension on iPhone

1. Open the Settings app.
2. Tap Apps, then tap Safari.
3. Tap Extensions.
4. Tap the extension you want to turn off.
5. Turn off Allow Extension.

Result: the extension stops working in Safari, but its app stays on your iPhone so you can turn it back on later. If you have Safari profiles set up, Apple says extensions are turned on per profile, so check each profile you use.

On older versions of iOS, Safari is listed directly in Settings rather than under Apps.

How to Turn Off an Extension for One Website

Apple lets you turn an extension on or off for an individual site without changing your overall Safari settings.

1. Open the website in Safari.
2. Tap the Page Menu button on the left side of the search field.
3. Tap Manage Extensions.
4. Turn each extension on or off.

Result: the change applies only to that website. This is useful when a content blocker or coupon extension breaks one site you rely on.

Extensions in Private Browsing

Apple says any Safari extensions that have access to browsing data are turned off automatically in Private Browsing. If you want one to work there, you can turn it on in that extension’s settings under Settings > Apps > Safari > Extensions.

If Private Browsing itself isn’t available, see why you can’t open a private tab in Safari.

How to Remove a Safari Extension Completely

Safari extensions come with apps, so deleting the app removes the extension. Apple’s steps:

1. Swipe down on the Home Screen and search for the extension.
2. Touch and hold its icon.
3. Tap Delete App, then follow the onscreen instructions.

Result: the extension disappears from your Safari settings. You can reinstall it from the App Store later.

If you created a custom extension with Apple Intelligence on iOS 27, Apple says to delete it from Safari instead: tap the Page Menu button, tap Manage Extensions, select the extension, then tap Delete Extension.

Why Turn Off an Extension?

• A site isn’t loading correctly: content blockers can hide parts of a page. Turn the extension off for that site and reload.
• Privacy: Apple recommends checking the extensions you have installed and making sure you know what they do. Some extensions collect personal data.
• Speed: Too many extensions can also slow down browsing.

Troubleshooting

• The extension isn’t listed: it may come from an app you deleted, or it may be on another device. Apple says extensions available on other platforms appear in Safari settings on your other devices signed in to the same Apple Account, so you can download them there.
• It turned itself back on: check the per-website setting in Manage Extensions and the setting for each Safari profile.
• You still see ads or blocked content: some changes need you to reload the page or close and reopen the tab.

Frequently Asked Questions

Does turning off an extension delete it?

No. It stays installed and keeps its settings. Only deleting the app removes it.

How do I find new extensions?

In Safari, tap the Page Menu button, then Manage Extensions. Apple says you can search, check Recommendations, or tap Browse Extensions to look in the App Store.
