Removing extensions from Safari is straightforward: open Safari settings, find the Extensions section, and delete the ones you no longer want
Safari extensions live in your browser settings, not scattered across your computer. Whether you installed something you no longer use, want to disable an extension temporarily, or suspect one is slowing down your browser, you can remove it in under a minute. The process differs slightly between Mac and iPhone, but both are simple enough that you do not need to restart Safari or your device.
Before you remove an extension, understand the difference between disabling and deleting. Disabling turns an extension off without removing it — you can turn it back on later without reinstalling. Deleting removes it completely, and you would need to reinstall it from the App Store if you change your mind. Most of the time, removing an extension is the right choice if you are not using it, because unused extensions can slow down your browser and create unnecessary access points to your browsing data.
Key Takeaways
- On Mac, open Safari, go to Safari menu > Settings > Extensions, select the extension, and click Uninstall.
- On iPhone or iPad, go to Settings > Safari > Extensions, tap the extension, and toggle it off or delete it entirely.
- Disabling an extension keeps it installed but turns it off; uninstalling removes it completely.
- Removing unused extensions can improve Safari's speed and reduce the number of apps with access to your browsing history.
How to remove extensions on Mac
Open Safari and click the Safari menu in the top-left corner of your screen. Select Settings (or Preferences on older versions of macOS). Click the Extensions tab at the top of the window.
You will see a list of all installed extensions on the left side. Click the extension you want to remove. On the right side, you will see details about that extension, including an Uninstall button. Click Uninstall, and Safari will ask you to confirm. Click Uninstall again, and the extension is gone.
If you want to disable an extension without removing it, you can uncheck the box next to "Show in menu" or toggle off the extension itself using the checkbox on the left. This keeps the extension installed but stops it from running.
How to remove extensions on iPhone and iPad
Open the Settings app on your device. Scroll down and tap Safari. Tap Extensions.
You will see a list of all extensions you have installed. Tap the extension you want to remove. You now have two options: toggle off the switch to disable it, or tap Delete to remove it completely. If you tap Delete, confirm your choice when prompted.
On iPhone and iPad, extensions are usually installed through the App Store as part of a larger app. If you delete an extension this way, the main app remains on your device — only the Safari extension is removed. If you want to remove the entire app, you would do that separately from the Home Screen or App Library.
What happens when you remove an extension
Once you remove an extension, it stops running immediately. Any data it was collecting about your browsing stops as well. If the extension had access to your passwords, browsing history, or other sensitive information, that access ends.
Some extensions modify how websites look or function. When you remove one, websites will return to their normal appearance and behavior. For example, if you had an ad-blocking extension, ads will reappear on websites you visit.
If you remove an extension by mistake, you can reinstall it from the App Store or the Safari Extensions gallery. You will not lose any settings you had configured in the extension, though — those are stored separately and will return if you reinstall the same extension.
Why you might want to remove an extension
The most common reason is that you simply do not use it anymore. Extensions run in the background even when you are not actively using them, which can slow down Safari and drain battery life on iPhone and iPad. Removing extensions you have not opened in months is a quick way to improve browser performance.
Another reason is privacy. Every extension you install has some level of access to your browsing activity. Some extensions request access to all websites you visit, your passwords, or your browsing history. If you do not trust an extension or do not understand why it needs that access, removing it is the safest choice.
You might also remove an extension because it is causing problems — crashing Safari, breaking certain websites, or displaying unwanted notifications. Removing the problematic extension usually fixes the issue immediately.
Checking what access your extensions have
Before you remove an extension, you can see exactly what it has access to. On Mac, open Safari Settings > Extensions, click the extension, and look at the "Access" section. It will tell you whether the extension can access all websites, specific websites, or only when you click it.
On iPhone, tap Settings > Safari > Extensions, select the extension, and look at the permissions listed. If an extension asks for access to all websites but you only use it on one or two sites, you can restrict its access by tapping "Allow" and selecting "Only on these websites" or "Ask when visiting other websites."
If you see an extension you do not recognize, that is a sign to remove it. Malicious extensions are rare on Safari because Apple reviews all extensions in the App Store, but removing anything you did not intentionally install is still a good practice.
Frequently Asked Questions
Will removing an extension delete my saved data or settings?
No. If you reinstall the same extension later, your settings and saved data will return. The extension stores this information separately from the extension file itself, so uninstalling does not erase it.
Can I disable an extension instead of removing it completely?
Yes. On Mac, uncheck the box next to the extension name in Settings. On iPhone, toggle off the switch next to the extension. The extension stays installed but stops running. You can turn it back on anytime without reinstalling.
Why is Safari running slowly after I installed an extension?
Some extensions consume a lot of memory or make many requests to websites, which slows down your browser. Try disabling the extension to see if Safari speeds up. If it does, you know that extension is the problem. You can then decide whether to remove it or keep it disabled.
What if I remove an extension and a website stops working?
Some websites depend on specific extensions to function properly. If removing an extension breaks a website, reinstall it and add the website to the extension's allowed list. On Mac, you can do this in Safari Settings > Extensions by clicking the extension and adjusting its access permissions.
Do I need to restart Safari after removing an extension?
No. Safari removes the extension immediately, and you do not need to restart the browser or your device. Any changes take effect right away.
