Removing an extension from Safari takes two steps: open Settings, find the Extensions tab, and uncheck or delete the one you want gone

Safari stores all your extensions in one place. To remove one, open Safari, go to Safari > Settings (or Safari > Preferences on older macOS versions), click the Extensions tab, find the extension in the list, and either uncheck the box next to it to disable it temporarily or click the minus button to remove it entirely. On iPhone and iPad, the process is slightly different: go to Settings > Safari > Extensions, tap the extension, and toggle it off or delete it.

The difference between disabling and deleting matters. Unchecking an extension keeps it installed but turns it off — you can turn it back on later without reinstalling. Clicking the minus button removes it completely, and you would need to reinstall it from the App Store if you change your mind. Most people delete extensions they no longer use rather than leaving them disabled.

Key Takeaways

  • On Mac, open Safari Settings, click Extensions, and uncheck or delete the extension you want to remove.
  • On iPhone and iPad, go to Settings > Safari > Extensions, then toggle off or delete the extension from there.
  • Unchecking an extension disables it without removing it; clicking the minus button deletes it completely.
  • Some extensions may require you to confirm the removal or may ask if you want to keep your data before they disappear.

Removing extensions on Mac

Start by opening Safari and clicking Safari in the menu bar at the top of your screen. If you are on macOS Monterey or newer, select Settings. On older versions, click Preferences. Either way, a window opens with several tabs across the top.

Click the Extensions tab. You will see a list of every extension you have installed, organized by category or all together depending on your Safari version. Find the extension you want to remove. Next to its name, you will see either a checkbox (which you can uncheck to disable it) or a minus button (which you can click to delete it). If you want to remove it completely, click the minus button. Safari will ask you to confirm — click Remove to finish.

If you only want to turn it off without deleting it, uncheck the box instead. The extension stays installed but stops running. You can re-enable it anytime by checking the box again. This is useful if you want to test whether an extension is causing a problem or if you only need it occasionally.

Removing extensions on iPhone and iPad

On iOS and iPadOS, extensions live in the Settings app rather than in Safari itself. Open Settings, scroll down, and tap Safari. Scroll down again until you see Extensions and tap it. You will see a list of every extension you have installed.

Tap the extension you want to remove. A menu appears with options to toggle it on or off, or to delete it. If you see a toggle switch, tap it to turn the extension off without removing it. If you see a Delete or Remove button, tap that to delete it completely. Some extensions may ask you to confirm or may offer to keep your saved data — read the prompt and choose what you prefer.

What happens after you remove an extension

Once you delete an extension, it stops running immediately. Any buttons or icons it added to Safari disappear, and any data it was tracking or storing stops being collected. If the extension had access to your browsing history or passwords, that access ends.

If you delete an extension by mistake, you can reinstall it from the App Store. Search for the extension by name, open its page, and click Get or the cloud icon to install it again. Your settings and saved data may or may not come back depending on how the extension was designed — some extensions store data in iCloud, while others store it locally and lose it when you uninstall.

Disabling vs. deleting: which one to choose

Disable an extension if you think you might use it again soon or if you are testing whether it is causing a problem. Disabling is faster than uninstalling and reinstalling, and it keeps your extension settings intact. Uncheck the box, test Safari for a few hours, and if the problem goes away, you know that extension was the culprit.

Delete an extension if you no longer use it or if it is causing problems you want to solve permanently. Deleted extensions free up a small amount of memory and remove any permissions they had. If you ever need it again, you can reinstall it from the App Store in under a minute.

Extensions that won't remove

Occasionally an extension will not delete, or the delete button will not appear. This usually means the extension is managed by your organization or by a parental control profile on your device. If you see a message saying the extension is managed, you will need to contact whoever set up that profile to remove it.

On a Mac, open System Settings, go to General > Profiles, and look for a profile that mentions extensions or Safari. If one exists, that is what is preventing removal. On iPhone or iPad, go to Settings > General > VPN & Device Management and look for a profile there. Removing the profile will let you remove the extension, though you may lose other settings that profile controlled.

Frequently Asked Questions

Will removing an extension delete my saved passwords or data?

Removing the extension itself does not delete passwords stored in Safari — those stay in your keychain. However, any data the extension stored separately (like custom settings or browsing history it tracked) will be lost. If you reinstall the extension later, that data will not come back unless the extension syncs it to iCloud.

Can I remove multiple extensions at once?

No, Safari requires you to remove extensions one at a time. Open Settings or Preferences, go to Extensions, and click the minus button next to each one you want to delete. On iPhone and iPad, you must tap each extension individually and delete it.

What if I remove an extension and Safari stops working?

Removing an extension should not break Safari itself. If Safari crashes or behaves strangely after you remove an extension, try restarting Safari or restarting your device. If the problem persists, it is likely unrelated to the extension you removed.

Do I need to restart Safari after removing an extension?

No, Safari removes extensions immediately. You do not need to close and reopen Safari for the change to take effect, though restarting never hurts if you want to be thorough.

Can I remove Safari's built-in extensions?

Safari comes with a few built-in extensions like Reader and Translation. You cannot delete these, but you can disable them by unchecking the box next to their names in the Extensions settings. They will not run unless you re-enable them.
