Finding and Installing Extensions in Chrome

To add an extension to Chrome, you go to the Chrome Web Store, find the extension you want, and click the "Add to Chrome" button. Chrome then asks you to confirm, installs it in seconds, and the extension appears as an icon in your toolbar. The whole process takes less than a minute.

The Chrome Web Store is Google's official marketplace for extensions. You reach it by typing chrome.google.com/webstore into your address bar, or by clicking the puzzle-piece icon in the top right of Chrome, then selecting "Open Chrome Web Store". Every extension there has been reviewed by Google before being listed, though that review checks for obvious malware rather than guaranteeing the extension does what it claims.

Once you find an extension you want, the "Add to Chrome" button appears prominently on its store page. Click it, and Chrome shows a popup listing what the extension can access — your browsing history, your passwords, the content of web pages you visit, or other sensitive information depending on what the extension needs to work. Read this list. If it asks for access to things it should not need, that is a sign to skip it. If the access makes sense, click "Add extension" to confirm.

Key Takeaways

  • The Chrome Web Store at chrome.google.com/webstore is the only safe place to find extensions, because Google reviews them before listing.
  • When you click "Add to Chrome", Chrome shows you exactly what data the extension can access — read this list before confirming.
  • After installation, the extension icon appears in your toolbar, usually in the top right corner next to the address bar.
  • You can turn extensions on and off, remove them entirely, or change what data they can access from the Extensions menu at any time.
  • Extensions from outside the Chrome Web Store can contain malware and should never be installed, even if someone you trust recommends them.

Where the Extension Icon Appears After Installation

After you install an extension, Chrome adds an icon to your toolbar — the row of buttons in the top right corner of the browser window. Some extensions show their icon all the time. Others only show it on certain websites where they work. If you install multiple extensions, their icons line up next to each other in the toolbar.

If you do not see an icon right away, the extension may be hiding. Click the puzzle-piece icon (it looks like four squares) in the top right corner of Chrome. A dropdown menu appears showing all your installed extensions. If an extension is there but you do not see its icon in the main toolbar, you can pin it so the icon shows all the time. Hover over the extension name in the dropdown and click the pin icon that appears.

Some extensions do their work silently in the background and do not need an icon at all. Password managers and ad blockers often work this way. If you are not sure whether an extension installed correctly, go back to the Chrome Web Store page for that extension — it will say "Remove from Chrome" instead of "Add to Chrome" if the extension is already installed.

Checking What an Extension Can Access

Every extension needs permission to do its job. A password manager needs access to your passwords. An ad blocker needs to see the content of every web page. A grammar checker needs to read what you type. Before you install, Chrome shows you exactly what the extension is asking for. This list is your chance to decide whether you trust it.

After installation, you can see and change these permissions at any time. Click the puzzle-piece icon in the top right, find the extension in the list, click the three dots next to its name, and select "Manage extension". A new page opens showing what the extension can do. Look for a section called "Permissions" or "Site access". If an extension asks to see all your browsing on all websites but only needs to work on one site, you can restrict it. Click "On specific sites" and type in the websites where you want it to work.

If an extension ever asks for new permissions — for example, if you update it and it suddenly wants access to your camera — Chrome notifies you. You can accept the new permission or remove the extension. Never ignore these notifications. If an extension you trusted suddenly asks for access it did not need before, that is a reason to uninstall it.

Removing Extensions You No Longer Use

To remove an extension, click the puzzle-piece icon in the top right corner of Chrome. Find the extension you want to remove, click the three dots next to its name, and select "Remove from Chrome". Chrome asks you to confirm, and the extension is gone when ready. Your data is not affected — removing an extension does not delete your passwords, browsing history, or anything else.

Removing extensions you do not use regularly is a good habit. Each extension running in the background uses a small amount of your computer's memory and can slow Chrome down slightly. If you installed something to try it out and decided you do not like it, remove it. You can always reinstall it later from the Chrome Web Store if you change your mind.

Turning Extensions On and Off Without Removing Them

If you want to pause an extension temporarily without removing it completely, you can turn it off. Click the puzzle-piece icon, find the extension, click the three dots next to its name, and select "Manage extension". On the extension's page, toggle the switch next to "Enabled" to turn it off. The extension stays installed but stops running. Toggle it back on whenever you want to use it again.

This is useful if an extension is causing problems on a specific website. You can turn it off, reload the page, and see if the problem goes away. If it does, you know the extension was the cause. You can then either remove the extension entirely or restrict it so it does not run on that website. To restrict it, go to the "Site access" section on the extension's page and choose "On specific sites" instead of "On all sites".

Staying Safe When Installing Extensions

Only install extensions from the Chrome Web Store. Extensions from other websites or email attachments can contain malware that steals your passwords, tracks your browsing, or damages your computer. Even if someone you know recommends an extension from outside the Web Store, do not install it. The safest version is always on the official store.

Before installing, check the extension's reviews and rating. Click on the "Reviews" tab on the store page and read what other people say. If many people report that an extension stopped working, changed what it does, or started showing ads, that is a warning sign. Look at the number of users — an extension with millions of users has been tested by more people than one with a few hundred.

Be especially careful with extensions that ask for broad permissions. An extension that wants to see all your browsing on all websites is asking for a lot of trust. If a simpler extension does the same job with fewer permissions, choose that one instead. You can always change your mind later and switch to a different extension.

Frequently Asked Questions

Can I use the same extension on multiple computers?

Yes. If you sign into Chrome with your Google account on another computer, your extensions sync automatically. The same extensions appear on that computer with the same settings. If you remove an extension on one computer, it removes from all of them. You can turn off syncing for extensions in Chrome Settings if you want different extensions on different computers.

What does it mean when an extension says it needs to "read and change all your data on websites you visit"?

It means the extension can see the content of every web page you visit and modify what you see on those pages. Password managers, ad blockers, and grammar checkers all need this permission to work. It sounds broad because it is — that is why you should only install extensions from sources you trust and check the reviews first.

Will removing an extension delete my saved passwords or data?

No. Removing an extension does not affect your Chrome passwords, bookmarks, browsing history, or any other data. The extension straightforward stops running. If you reinstall it later, it starts fresh without any of the settings you had before, but your Chrome data remains untouched.

Why is an extension asking for permission to access my camera or microphone?

Some extensions need camera or microphone access to work — video conferencing tools, for example. Before you allow it, make sure the extension actually needs that access. If a straightforward note-taking app asks for your camera, that is suspicious and you should not grant it. You can always deny the permission and the extension will tell you it cannot work without it.

Can I install extensions on Chrome on my phone?

Chrome on Android phones does not support extensions the way desktop Chrome does. You can install some extensions on Chrome for iPhone, but the selection is limited. For most extensions, you need to use Chrome on a computer or laptop. Some features that extensions provide on desktop — like ad blocking — are built into mobile browsers instead.
