Where to find Chrome extensions
Chrome extensions live in the Chrome Web Store, which you reach directly from your browser. Click the puzzle-piece icon in the top right corner of Chrome (next to your profile picture), then select "Manage extensions." From there, click the blue button labeled "Open Chrome Web Store" at the bottom left, or go directly to chromewebstore.google.com in your address bar.
The Web Store shows you thousands of extensions organized by category — productivity, shopping, security, writing tools, and others. You can search by name if you already know what you want, or browse by category to discover new ones. Each extension has a description, user reviews, screenshots, and the number of users who have installed it.
Not every extension you find online is in the Chrome Web Store. Some developers distribute extensions through their own websites or GitHub, but those require manual installation and carry more risk. For most people, the Web Store is the safest and easiest place to look.

Installing an extension in three steps
Once you find an extension you want, installing it takes almost no time. Click the blue "Add to Chrome" button on the extension's page. A popup will appear asking you to confirm — it will show you what permissions the extension needs, like access to your tabs or your browsing history. Click "Add extension" to proceed.
The extension installs immediately. You will see a confirmation message, and the puzzle-piece icon in your browser's top right corner will show a number indicating how many extensions you have installed. Some extensions add their own icon next to the puzzle piece for quick access; others only appear in the extensions menu.
To remove an extension, click the puzzle-piece icon, find the extension you want to remove, click the three dots next to it, and select "Remove from Chrome." You can also manage extensions from the same "Manage extensions" page where you first found the Web Store link.
What permissions mean and why they matter
When you install an extension, Chrome shows you a list of permissions — things the extension is allowed to do on your computer. Common ones include "read and change all your data on websites you visit" or "see your browsing history." These permissions exist because many extensions need access to what you are doing in order to work. A grammar checker needs to read the text you type; a password manager needs access to your login forms.
The key is matching the permission to the extension's purpose. If a simple note-taking extension asks for permission to access all your browsing history, that is a red flag — it does not need that to work. Read the extension's description and reviews to understand why it needs each permission. If something does not make sense, look for a different extension that does the same job with fewer permissions.
You can also limit what an extension can do after you install it. Click the puzzle-piece icon, find the extension, click the three dots, and select "Details." Scroll down to "Permissions" and you will see options to restrict the extension to specific websites or to limit when it runs.
Checking reviews and user count before installing
The Chrome Web Store shows you how many people have installed each extension and what rating it has. A large user base (hundreds of thousands or millions) and recent positive reviews are good signs. Extensions with very few users or mostly negative reviews are riskier — they may not work well, or they may have security problems.
Read the recent reviews, not just the overall rating. Look for comments about whether the extension actually does what it claims, whether it slows down your browser, and whether the developer responds to problems. If you see multiple complaints about the same issue, that extension probably is not worth your time.
Be especially careful with extensions that ask for broad permissions but have few users or poor reviews. A well-known extension from a reputable developer with thousands of positive reviews is much safer than an unknown one, even if both claim to do the same thing.
Managing extensions you have already installed
Click the puzzle-piece icon in the top right corner to see all your installed extensions at a glance. From here you can turn extensions on and off without removing them — useful if an extension is slowing down your browser or interfering with a website. Click the toggle next to the extension's name to disable it; click again to turn it back on.
You can also pin extensions to your toolbar so their icon appears next to the address bar for quick access, or unpin them to keep your toolbar clean. Click the pin icon next to the extension's name. Extensions you pin will stay visible; unpinned ones only appear when you click the puzzle-piece icon.
If an extension stops working or you no longer need it, remove it from the same menu. Removing an extension does not delete your data — if you reinstall it later, your settings will still be there (though this depends on how the extension stores its data).
Fixing problems when an extension will not install
Most of the time, installing an extension works without any trouble. If you click "Add to Chrome" and nothing happens, try refreshing the page and clicking again. If that does not work, restart your browser completely — close all Chrome windows and open it again.
Some extensions are not available in all countries or regions. If you see a message saying the extension is not available in your location, you will not be able to install it through the Web Store. A few extensions also require you to be signed into your Google account; if you are not signed in, you will see a prompt to do so before you can install.
If you installed an extension and it is not working, check that it is turned on (click the puzzle-piece icon and look for the toggle). If it is on but still not working, try disabling other extensions to see if something is interfering with it. You can also uninstall and reinstall the extension to reset it.
The difference between Chrome extensions and Chrome apps
Chrome extensions are small programs that change how your browser works — they add features, block ads, manage passwords, or modify websites. Chrome apps are different: they are full applications that run inside Chrome, like a calculator or a to-do list. Apps appear in your Chrome apps page (type chrome://apps in the address bar), not in your extensions menu.
For most people, extensions are what you want. They integrate with your browser and websites. Apps are less common now because web applications (programs that run in any browser) have become more powerful. If you are looking for a tool to do something specific, start by searching the Web Store for an extension. If you cannot find one, then look for an app or a web application.
Frequently Asked Questions
Can I use the same extension on multiple computers?
Yes. If you are signed into your Google account on multiple computers, your extensions sync automatically across all of them. Install an extension on one computer, and it will appear on your other computers within a few minutes. You can turn off this sync in Chrome settings if you want different extensions on different computers.
Do extensions slow down my browser?
Most extensions have minimal impact on speed, but some do slow things down, especially if they run constantly in the background. If your browser feels slow, disable extensions one at a time to see which ones are the culprit. You can keep the ones you use most and remove the rest, or disable extensions you do not use every day.
Is it safe to install extensions from the Chrome Web Store?
The Chrome Web Store is safer than installing extensions from random websites, but not every extension is trustworthy. Google reviews extensions before they appear in the store, but malicious ones sometimes slip through. Stick with extensions that have many users, recent positive reviews, and clear purposes. Avoid extensions that ask for permissions that do not match what they claim to do.
What happens to my extension settings if I uninstall it?
When you uninstall an extension, Chrome deletes the extension's data by default. If you reinstall it later, your settings will be gone. Some extensions back up their data to your Google account, so your settings might return when you reinstall — check the extension's description to see if it offers this feature.
Can I install extensions on Chrome on my phone?
Chrome on Android and iPhone does not support extensions the way desktop Chrome does. Mobile Chrome has a limited set of built-in features and does not allow third-party extensions. If you need extension features on your phone, you will need to use a different browser or find a mobile app that does the same job.
