Removing an extension takes one click, but where that click is depends on what you're trying to do
To remove an extension from your Chromebook, open Chrome, click the puzzle-piece icon in the top right corner of the browser window, find the extension you want to remove, click the three dots next to it, and select "Remove from Chrome." The extension disappears immediately and stops running on your device.
If you can't see the puzzle-piece icon, the extension menu may be hidden. Look for a small arrow pointing left at the far right of your address bar — click that to reveal hidden extensions, then follow the same steps.
Some extensions install themselves without you noticing, or you may have installed one months ago and forgotten about it. Removing unused extensions makes your browser faster and closes potential security gaps, since every extension has access to some of your browsing activity.
Key Takeaways
- The puzzle-piece icon in the top right corner of Chrome opens your extension menu, where you can see every extension installed on your Chromebook.
- Click the three dots next to any extension and select "Remove from Chrome" to uninstall it permanently.
- Removing an extension stops it from running immediately — you do not need to restart your browser or Chromebook.
- If an extension keeps reinstalling itself after you remove it, check your Chromebook's installed programs (Settings > Apps > Manage your apps) and uninstall the program that came with it.
Finding the extension menu on your Chromebook
The puzzle-piece icon sits in the top right corner of your Chrome window, next to the profile picture icon and the three-dot menu. Click it once to see a dropdown list of all your extensions. Each one shows its name, a small icon, and a three-dot menu button on the right side.
If you do not see the puzzle-piece icon, your extensions are hidden. Look for a small arrow pointing left at the far right of the address bar (the white box where you type web addresses). Click that arrow to reveal your extensions, then click the puzzle-piece icon that appears.
You can also reach your extensions through the three-dot menu: click the three dots in the top right, select "More tools," then "Extensions." This opens a full page showing every extension on your Chromebook with more details about each one.
Removing an extension you no longer want
Open the extension menu by clicking the puzzle-piece icon. Find the extension you want to remove, click the three dots on the right side of its name, and select "Remove from Chrome." A small popup will ask you to confirm — click "Remove" again, and the extension is gone.
The extension stops working immediately. You do not need to restart Chrome or your Chromebook. Any data the extension stored (like saved passwords or settings) is deleted when you remove it, so if you ever reinstall the extension later, it will start fresh.
If you are not sure what an extension does, you can click on its name instead of the three dots. This opens a details page that shows what permissions the extension has — for example, whether it can see everything you type, or only run on certain websites. This information can help you decide whether to keep it.
Stopping extensions that reinstall themselves
Some extensions come bundled with other software you installed. If you remove an extension and it comes back the next time you restart Chrome or your Chromebook, the program that installed it is probably reinstalling it automatically.
To stop this, you need to uninstall the program itself. On your Chromebook, click the time in the bottom right corner, then click the settings icon (a gear). Go to "Apps" in the left menu, then "Manage your apps." Look through the list for any program you do not recognize or do not use, click it, and select "Uninstall." After you uninstall the program, the extension should stop coming back.
If you are still not sure which program is causing the problem, look at the extension's details page (click its name in the extension menu). The "Source" line at the bottom sometimes shows which program installed it.
Disabling an extension without removing it
If you want to turn off an extension temporarily but keep it installed, you can disable it instead of removing it. Open the extension menu, click the three dots next to the extension, and select "Turn off." The extension stops running, but it stays in your list and you can turn it back on later by clicking the same menu and selecting "Turn on."
Disabling is useful if an extension causes problems with a particular website but you still want to use it elsewhere. You can also disable all extensions at once by clicking the three-dot menu in the top right, selecting "More tools," then "Extensions," and toggling off the switch next to "Developer mode" at the bottom of the page — though this is rarely necessary.
Controlling which websites an extension can access
Instead of removing an extension entirely, you can limit what it sees. Open the extension menu, click the three dots next to the extension, and select "Manage extension." On the page that opens, scroll down to "Site access" and choose one of three options: "On all sites," "On specific sites," or "On click only."
"On click only" is the most private option — the extension only runs when you click its icon in the extension menu. "On specific sites" lets you type in the websites where you want it to work. This is useful if an extension is useful on one site but you do not want it watching your activity everywhere else.
Frequently Asked Questions
Will removing an extension delete my passwords or saved data?
Yes. When you remove an extension, all data it stored on your Chromebook is deleted. If you reinstall the extension later, it will not remember your settings or passwords. If you think you might use the extension again, disable it instead of removing it — disabled extensions keep their data.
Can I remove extensions that came with Chrome?
Chrome itself does not come with extensions pre-installed. If you see extensions you did not install, they were added by another program or by someone else with access to your Chromebook. You can remove any extension, including ones installed by programs you downloaded.
What if I accidentally remove an extension I need?
You can reinstall it by visiting the Chrome Web Store, searching for the extension by name, and clicking "Add to Chrome." Your Chromebook will download and install it again. If you do not remember the extension's name, look through your browser history or think about what task you were using it for.
Do I need to remove extensions to speed up my Chromebook?
Removing unused extensions can help, especially if you have many installed. Each extension uses a small amount of memory and can slow down your browser slightly. Disabling extensions instead of removing them has the same effect on speed but lets you turn them back on later if you need them.
Why does an extension keep asking for permission to access my data?
This usually means the extension's permissions changed, or Chrome is asking you to confirm permissions again for security reasons. You can see exactly what an extension wants to access by clicking its name in the extension menu and looking at the "Permissions" section. If you do not want to grant those permissions, remove the extension.
