How to Remove Safari Extensions on Mac

I am a longtime Mac user who likes to keep Safari lean, fast, and private, and removing unnecessary extensions is one of the easiest ways to do that. Over time, some extensions turn into memory hogs, break websites after macOS updates, or get bundled with apps that sneak in permissions; cleaning them out keeps Safari snappy and reduces privacy risk. Below is the exact, no-nonsense process I use to disable or fully uninstall Safari extensions on macOS, including the special case where an extension is part of a Mac app and can’t be deleted from Safari until the app is removed.

Quick ways to remove Safari extensions

• Standard method in Safari:
  • Open Safari → Safari menu → Settings (or Preferences on older macOS) → Extensions → select the extension → Uninstall to remove, or uncheck to temporarily turn off.
• If the Uninstall button says the extension is part of an app:
  • Click Show in Finder and delete the related app from Applications, then the extension disappears from Safari automatically.
• Manual removal for older macOS (10.14 or earlier):
  • Close Safari, open Finder → Go → Go to Folder → paste ~/Library/Safari/Extensions → delete the target extension file, then relaunch Safari.
• Tip for profiles (Sonoma feature):
  • Extensions can be profile-specific; remove or manage them per profile in Safari Settings → Profiles if relevant.

Step-by-step: Disable vs. Uninstall

1. Turn off an extension (safe test)

• Safari → Settings/Preferences → Extensions → uncheck the box next to the extension to disable it without deleting.
• Use this to test whether an extension is the cause of slowness, crashes, page rendering bugs, or pop-ups.

2. Fully uninstall an extension

• Safari → Settings/Preferences → Extensions → select the extension → Uninstall.
• If Safari says the extension belongs to an app, choose Show in Finder and remove that app from Applications to complete the uninstall.

3. If the extension won’t show up or won’t remove

• On older systems, quit Safari and delete from the user Extensions folder: ~/Library/Safari/Extensions, then relaunch Safari.
• Make sure you’re looking in the right Safari profile if using Safari Profiles (Sonoma+): Safari → Settings → Profiles → select profile to manage items tied to that profile.
• Apple’s guidance: go to Safari Settings → Extensions to uninstall or turn off; remove the developer’s app if it’s app-bound.

What’s different in newer macOS versions

• Many Safari “extensions” are packaged as App Store apps or app extensions; uninstalling the parent app removes the extension.
• Safari Profiles keep separate sets of extensions per profile; remove or adjust extensions in each profile as needed.

Signs an extension should go

• Unfamiliar toolbar icons, new pop-ups, unexpected redirects, sluggish page loads, or permissions that don’t match the extension’s job are all red flags; best to disable first, then uninstall if the problem clears.

Extra notes

• Where to find the official how-to: Apple Support’s Safari extensions page shows where to disable and uninstall extensions in Safari Settings.
• Legacy manual deletion: Only use the ~/Library/Safari/Extensions method on older macOS where the GUI doesn’t cleanly remove the item.
• Community walkthroughs: The same core steps—Safari → Preferences/Settings → Extensions → Uninstall—apply across macOS versions in most tutorials.

FAQ

• How do I temporarily turn off a Safari extension without deleting it?
  Open Safari → Settings/Preferences → Extensions, then uncheck the extension to disable it; re-check to enable again.
• Safari says the extension is part of an app—how do I remove it?
  Click Show in Finder from the Uninstall prompt, delete the associated app in Applications, and the extension is removed with it.
• I don’t see my extension in the list—where else can I remove it?
  On older macOS, quit Safari and delete it from ~/Library/Safari/Extensions, then relaunch Safari; on newer macOS, ensure you’re viewing the correct Safari Profile in Settings → Profiles.
• Is there an official Apple guide for this?
  Yes—Apple’s support article explains how to turn off or uninstall extensions in Safari Settings → Extensions.
• Do extensions differ by profile in Safari on Sonoma or later?
  Yes, profiles can keep separate extension sets; manage or delete them per profile in Safari → Settings → Profiles.
• Will uninstalling an extension affect my bookmarks or history?
  No, removing an extension doesn’t delete bookmarks or history; profile deletions do remove profile-specific data, but uninstalling extensions alone does not.
• What’s the fastest “clean sweep” method if I suspect a bad extension?
  Disable all extensions in Safari Settings → Extensions, test Safari, then uninstall the suspicious ones; if an item is app-bound, remove its parent app from Applications.
• Can I remove Safari itself to get rid of everything?
  Safari is a protected system app on current macOS and isn’t intended to be removed; focus on removing or disabling extensions instead.
