Remove an extension in three clicks

Open Chrome and click the puzzle piece icon in the top right corner of your browser window. This icon shows all your installed extensions. Find the extension you want to remove, click the three dots next to it, and select "Remove from Chrome." Chrome will ask you to confirm — click "Remove" again, and it is gone.

That is the fastest way. If you cannot see the puzzle piece icon, your extensions may be hidden. Click the three vertical dots at the far right of your address bar, hover over "Extensions," and you will see the same list.

Once you remove an extension, Chrome stops running it when ready. Any data that extension stored — like saved passwords or settings — is deleted too. You can reinstall it later if you change your mind, but you will have to set it up from scratch.

Key Takeaways

  • The puzzle piece icon in your top right corner shows all extensions; click the three dots next to any extension and select "Remove from Chrome."
  • Removing an extension deletes any data it stored, like passwords or settings, so you cannot recover those if you reinstall it later.
  • You can also manage extensions through Chrome's settings menu by going to Settings > Extensions, where you can disable extensions without removing them.
  • Disabling an extension stops it from running but keeps it installed, so you can turn it back on without setting it up again.
  • Some extensions may have left behind files or settings in websites you visited; removing the extension does not undo those changes.

Find extensions you forgot you had

If you have installed many extensions over time, you may not remember what is running. Open Chrome's settings by clicking the three vertical dots in the top right, then select "Settings." On the left side, click "Extensions." You will see every extension you have installed, whether it is turned on or off, and when you added it.

This view also shows you what each extension can do. Look at the "Permissions" line under each one — it tells you what data that extension can access. An extension that can read all your websites, for example, will show "Read and change all your data on websites you visit." If an extension has permissions you do not want it to have, removing it is the safest choice.

Disable instead of remove if you might use it again

Removing an extension is permanent until you reinstall it. If you are not sure whether you want to keep something, disable it first. Go to Settings > Extensions, find the extension, and toggle the switch to "Off." The extension will stop running, but it stays installed and all its data stays on your computer.

When you disable an extension, Chrome stops loading it when you open the browser, and websites cannot interact with it. You will not see any slowdown from a disabled extension. If you decide you want it back, just toggle the switch to "On" and it works exactly as it did before, with all your old settings intact.

Clean up extensions that slow down your browser

Extensions run in the background and use memory and processing power, even when you are not actively using them. If your Chrome browser feels slow, removing unused extensions can help. Open Settings > Extensions and look at the list. Remove anything you have not used in months, or anything you installed by accident and forgot about.

You can also check how much memory each extension is using. Click "Details" under any extension to see its resource usage. If one extension is using a lot of memory, you can disable it or remove it and look for a lighter alternative that does the same job.

Remove malicious or unwanted extensions

Sometimes extensions get installed without your permission, or an extension you trusted starts behaving badly — showing ads, redirecting your searches, or stealing your data. Remove it when ready. Go to Settings > Extensions, find it, and click "Remove."

After you remove a suspicious extension, run a malware scan. Click the three vertical dots, go to Settings, then scroll down and click "Reset and clean up." Select "Clean up computer" and let Chrome scan for harmful software. This will not undo any damage the extension already did, but it will remove any other malicious files it may have installed.

If an extension keeps reinstalling itself after you remove it, something else on your computer may be putting it back. Restart your computer in Safe Mode and remove the extension again. If it still returns, you may need to run a full antivirus scan or contact a technician.

Manage extension permissions to limit what they can do

You do not have to remove an extension to control what it can access. Go to Settings > Extensions, click "Details" on any extension, and scroll down to "Permissions." You can change when the extension runs — for example, you can tell it to work only on certain websites instead of all websites.

Click "On specific sites" and enter the web addresses where you want the extension to work. This way, an extension that needs access to your email can work on Gmail but nowhere else. This reduces the risk if the extension is compromised or behaves unexpectedly.

Frequently Asked Questions

Does removing an extension delete my passwords or data from websites?

No. Removing an extension deletes only the data that extension itself stored — like its settings or saved information. Your passwords, browsing history, and data on websites stay on your computer and in those websites. The extension just stops running.

Can I remove an extension that came with Chrome?

Most extensions that come built into Chrome cannot be removed, but you can disable them. Go to Settings > Extensions and toggle off any extension you do not want running. If you see a "Remove" button, you can remove it; if you only see a toggle, you can only disable it.

What happens if I remove an extension and then reinstall it?

The extension will work, but all its settings and saved data are gone. You will have to set it up again from the beginning, just like the first time you installed it. This is why disabling is better if you think you might use it again.

Why does an extension keep coming back after I remove it?

Another program on your computer may be reinstalling it automatically. Restart your computer in Safe Mode, remove the extension again, and run a full antivirus scan. If it keeps returning, you may have malware that needs professional removal.

Can I remove multiple extensions at once?

No, Chrome requires you to remove extensions one at a time. Go to Settings > Extensions and click the "Remove" button for each one you want to delete. If you have many to remove, it takes a few minutes, but the process is straightforward.
