Remove an extension in three clicks

Open Chrome and click the puzzle-piece icon in the top right corner of your browser window. This shows all your installed extensions. Find the one you want to remove, click the trash icon next to it, and confirm the deletion. The extension is gone when ready — Chrome does not keep a copy running in the background.

If you do not see the puzzle-piece icon, extensions may be hidden. Click the three vertical dots (menu) in the top right, select "Extensions," then "Manage extensions." You will see the same list and the same trash icons.

Removing an extension does not delete your browsing history or passwords. It only stops that specific tool from running. If you change your mind later, you can reinstall it from the Chrome Web Store and your settings will be fresh — Chrome does not save extension data after removal.

Key Takeaways

  • Click the puzzle-piece icon in the top right, find the extension, and click the trash icon to remove it permanently.
  • Removing an extension stops it from running but does not affect your passwords, bookmarks, or browsing history.
  • If an extension is slowing down Chrome or using too much memory, you can turn it off temporarily without deleting it.
  • Some extensions run in the background even when you are not using them — disabling them can improve battery life on laptops.
  • You can reinstall a removed extension later from the Chrome Web Store, but it will start with default settings.

Turn off an extension without deleting it

If you want to test whether an extension is causing problems but are not ready to remove it, you can disable it instead. Open the Extensions menu (puzzle-piece icon or menu > Extensions > Manage extensions), find the extension, and toggle the switch to the off position. The extension stays installed but stops running.

This is useful when an extension is slowing down your browser or draining your battery. Leave it off for a day or two and see if Chrome feels faster. If it does, you have found the culprit. If not, turn it back on and test a different one.

Disabled extensions do not collect data, run background processes, or interfere with other tools. They take up almost no memory. You can turn them back on anytime by toggling the switch again.

Remove extensions that came pre-installed or hidden

Some extensions install themselves when you read other software, or they come bundled with Chrome updates. These are harder to spot because they may not show up in your Extensions menu right away.

To find hidden extensions, open the Extensions menu and look for a toggle labeled "Show extensions from other sources" or similar wording — the exact label varies by Chrome version. Turn it on. You will now see extensions that did not come from the Chrome Web Store. These are often the ones causing unexpected behavior.

Once you find the unwanted extension, click the trash icon to remove it. If you cannot find the trash icon, the extension may be managed by your organization or school — in that case, contact your IT department or administrator, because you do not have permission to remove it yourself.

Check what extensions are running right now

Extensions that run in the background use memory and battery power even when you are not actively using them. To see which ones are active, click the puzzle-piece icon and look for a toggle labeled "Allow in Incognito" or a small indicator showing the extension is running.

You can also check Chrome's task manager to see how much memory each extension is using. Press Shift + Esc on Windows or Command + Option + Esc on Mac. A window will open showing every process running in Chrome, including extensions. Look for entries labeled with extension names and note which ones are using the most memory.

If an extension is using a lot of memory but you do not use it often, disable it or remove it. This is especially helpful on older computers or laptops where battery life matters.

Reinstall an extension you removed by mistake

If you delete an extension and then realize you need it, go to the Chrome Web Store and search for it by name. Click "Add to Chrome" and confirm. The extension will reinstall, but it will have default settings — Chrome does not save your old configuration after you remove an extension.

If you had custom settings in that extension (like passwords saved in a password manager, or preferences in an ad blocker), you will need to set them up again. This is why it is safer to disable an extension first if you are unsure whether you want to keep it.

Some extensions are no longer available in the Chrome Web Store because the developer stopped supporting them or removed them. If you cannot find an extension you used before, it may have been discontinued. Search online for the extension name plus "discontinued" or "removed" to find out what happened.

Prevent unwanted extensions from installing in the future

Extensions often install without your knowledge when you read software from third-party websites or click on ads. To reduce this, read software only from official websites or trusted app stores. When you read something, read the installation screen carefully — many installers ask permission to add extensions, and the permission is buried in small text or a pre-checked box.

Uncheck any boxes that say "Install recommended extensions" or "Add toolbar" before you click Finish. If an extension installs anyway, remove it using the steps above and then check your browser settings to see if anything else changed.

You can also turn off automatic extension updates if you want to review changes before they take effect. Open Chrome Settings, go to Extensions > Manage extensions, and look for an option to disable automatic updates. This gives you control over what changes in your browser, though it means you will need to manually update extensions to get security fixes.

Frequently Asked Questions

Will removing an extension delete my saved passwords or bookmarks?

No. Passwords, bookmarks, and browsing history are stored separately from extensions. Removing an extension only stops that tool from running. Your data stays in Chrome.

Can I remove an extension if my school or workplace installed it?

Not always. If your organization manages your Chrome account, some extensions may be locked and you cannot remove them. Contact your IT department or administrator to request removal.

What is the difference between disabling and removing an extension?

Disabling turns it off but keeps it installed — you can turn it back on anytime. Removing deletes it completely. If you reinstall it later, it will have default settings. Disable first if you are unsure.

Why is my extension still running after I disabled it?

Make sure the toggle is actually in the off position — sometimes it is hard to see. If it is off and the extension is still running, try removing it completely and restarting Chrome. If the problem continues, the extension may be managed by your organization.

How do I know if an extension is slowing down my browser?

Open Chrome's task manager (Shift + Esc on Windows, Command + Option + Esc on Mac) and look at the memory column. Disable the extension using the most memory and see if Chrome feels faster. If it does, that extension was the problem.
