How to remove Chrome extensions on Mac

To remove a Chrome extension on a Mac, open Chrome and click Window → Extensions in the menu bar. Then click Remove on the extension’s card and confirm. To stop an extension for a while without deleting it, turn off its switch on the same card.

This guide covers both ways to open Chrome’s Extensions page, removal with App Cleaner & Uninstaller, and the Chrome sync setting that can block it. I took every screenshot on macOS 27 Golden Gate in October 2026.

All browser extensions in one list

App Cleaner & Uninstaller by Nektony lists the extensions of your web browsers in one window and shows how much disk space each Chrome extension takes. Select the ones you no longer need and remove them in a few clicks. The same app uninstalls unused apps with their service files and manages startup programs.

What Chrome extensions are and why remove them

Browser extensions are small programs that add features to Chrome. They block ads, translate pages, fill in passwords, and check your grammar. Most of them come from the Chrome Web Store.

Extensions are handy, but each extra one has a cost:

• Speed. Active extensions use memory and processor time. The more of them you run, the slower Chrome and your Mac can get.
• Disk space. Extensions keep their own data files on your Mac. On my Mac, AdBlock’s files took over 350 MB, and Grammarly’s took over 100 MB.
• Privacy. Many extensions can read and change the pages you open. A malicious extension can track your browsing or save the passwords you type.
• Security. Even popular extensions get hacked, and one bad update can turn a trusted extension into malware.

Disable or remove?

• Disable an extension you need once in a while. It stays installed with its settings, and one click on its switch brings it back.
• Remove an extension you no longer use. Chrome deletes it, and to use it again, you install it again from the Chrome Web Store.

How to remove or disable Chrome extensions manually

chrome://extensions

From the Window menu

1. Open Google Chrome.
2. In the menu bar, click Window → Extensions.
3. Find the extension. If the list is long, type its name in Search extensions at the top of the page.
4. To disable the extension, turn off the switch on its card. To delete it, click Remove.
5. In the dialog, click Remove to confirm. Tick Report abuse only if the extension misbehaved and you want to report it to Google.

From the Chrome menu

1. Click the three-dot button (⋮) in the top-right corner of the Chrome window.
2. Choose Extensions → Manage extensions.
3. On the Extensions page, turn off the extension’s switch to disable it. To delete it, click Remove and confirm.

The same submenu has Visit Chrome Web Store. Use it to install a removed extension again or to find a replacement.

How to remove Chrome extensions with App Cleaner & Uninstaller

App Cleaner & Uninstaller by Nektony finds the extensions of your web browsers and lists them in one window, grouped by browser. Next to each Chrome extension, it shows how much disk space its files take. This way, you see the heavy extensions before you decide what to remove.

1. Download and launch App Cleaner & Uninstaller.
2. Click Extensions in the sidebar and select Web Browser Extensions.
3. In the Google Chrome Extensions group, tick the extensions you want to delete.
4. Click Remove. The Review and confirm removal of selected items window lists each selected extension with its files and their size.
5. Check the list and click Remove. If Chrome is open, the app also asks you to quit it. Quit Chrome and click Continue.

App Cleaner & Uninstaller moves the removed files to the Trash, so you can put them back until you empty the Trash.

How to turn off extension sync in Google Chrome

App Cleaner & Uninstaller can’t remove a Chrome extension that syncs to your Google account. Instead of a checkbox, it shows an ⓘ icon with this tooltip: “This extension cannot be removed because synchronization is turned on in Google Chrome. Turn off sync to remove Google Chrome extensions.”

Chrome no longer has a single Turn off sync button. Each type of synced data has its own switch on the Your account page. So the tooltip’s “Turn off sync” now means turning off the Extensions switch on that page.

Option 1. Stop syncing only extensions

1. In Chrome’s menu bar, click Chrome → Settings.
2. Click You and Google in the sidebar. Then click your account card with your name and email at the top of the page.
3. On the Your account page, find In your Google Account and turn off Extensions.
4. Go back to App Cleaner & Uninstaller. Checkboxes now replace the ⓘ icons next to your Chrome extensions, so you can select them and click Remove.

With Extensions off, your extensions stay only on this Mac. In Chrome’s words, data with its switch off “is saved only to this device.” Bookmarks, passwords, history, and the other items with their switches on keep syncing to your Google account.

Option 2. Sign out of Chrome

The Sign out of Chrome button sits at the top of the same Your account page. It disconnects Chrome on this Mac from your Google account, so Chrome stops syncing every item on the list, extensions included. Choose it only if you want to stop syncing all your Chrome data.

Final thoughts

Keep only the Chrome extensions you use. Turn off the ones you need now and then, and remove the rest on Chrome’s Extensions page. To see how much space each extension takes and clean up several browsers in one window, use App Cleaner & Uninstaller.

If App Cleaner & Uninstaller shows an ⓘ icon next to a Chrome extension, turn off the Extensions switch on Chrome’s Your account page, and the extension gets a checkbox. If Chrome still feels slow after the cleanup, see our guide to fixing a slow Mac browser.
