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, then select "Manage extensions." From there, click the blue "Open Chrome Web Store" button, or go to chromewebstore.google.com in your address bar.
The Web Store shows you extensions by category — productivity, shopping, security, developer tools — or you can search by name. Each extension has a page showing what it does, how many people use it, user reviews, and what data it can access. Read the permissions section before installing anything; an extension that needs access to "all your data on all websites" is asking for more than one that only needs to see what you're reading on shopping sites.
Not every tool you find online is in the Web Store. Some developers distribute extensions outside it, but that route requires manually downloading a file and dragging it into Chrome — a process that's slower and riskier. For most people, the Web Store is the only place you need to look.
Key Takeaways
- The Chrome Web Store is built into your browser; click the puzzle-piece icon and select "Manage extensions" to reach it.
- Before installing, check what data the extension can access — permissions tell you whether it can see only the current page or all your browsing.
- Installing an extension takes one click on the "Add to Chrome" button, and it starts working when ready in most cases.
- You can turn extensions on and off, remove them, or restrict them to specific websites without uninstalling them completely.
- If an extension stops working or behaves strangely, disabling and re-enabling it often fixes the problem.
Installing an extension in three steps
Once you've found an extension you want, installation is straightforward. Click the blue "Add to Chrome" button on its Web Store page. A popup will appear listing the permissions it needs — read this carefully, because it tells you what data the extension can see. Click "Add extension" to confirm.
The extension installs when ready and usually starts working right away. You'll see a new icon appear next to the puzzle-piece icon in your toolbar, or it will add itself to the extensions menu. Some extensions need you to sign in or adjust settings before they work fully — the extension's page will tell you if that's the case.
If you change your mind, removing an extension is just as straightforward. Click the puzzle-piece icon, find the extension in the list, click the three dots next to it, and select "Remove from Chrome." It disappears completely, and any data it stored is deleted.
Understanding extension permissions
When you install an extension, Chrome shows you what it's allowed to do. Some permissions are broad — "read and change all your data on the websites you visit" — while others are narrow, like "read what's on the current page." The more access an extension requests, the more careful you should be about whether you trust it.
A password manager needs broad access because it has to see login forms everywhere. A tool that highlights prices on shopping sites only needs to see shopping websites. If an extension's permissions don't match what it claims to do, that's a red flag. For example, if a note-taking app asks to see all your browsing history, something is off.
You can also restrict an extension after installing it. Click the puzzle-piece icon, find the extension, click the three dots, and select "Manage extension." Under "Site access," you can choose to let it run only on specific websites, only when you click it, or on all sites. This is useful if you want to use an extension but don't want it watching everything you do.
Finding your installed extensions and turning them on or off
All your installed extensions live in one place. Click the puzzle-piece icon in the top right of Chrome, and you'll see a list of every extension you've added. Each one has a toggle switch next to it — click the switch to turn it off without removing it, or click it again to turn it back on.
Turning an extension off is useful when it's causing problems or slowing down your browser, but you might want to use it again later. Disabling it keeps your settings and data intact. If you're done with it permanently, click the three dots next to the extension name and select "Remove from Chrome."
Some extensions add their own buttons or menus to Chrome. If you want to hide an extension's icon to keep your toolbar clean, right-click the icon and select "Hide in Chrome menu." The extension still runs; its icon just moves to the puzzle-piece menu instead of showing in your toolbar.
What to do when an extension stops working
Extensions sometimes break after a Chrome update, or they stop responding for no obvious reason. The first thing to try is disabling and re-enabling it. Click the puzzle-piece icon, find the extension, and toggle it off. Wait a few seconds, then toggle it back on. This fixes most temporary problems.
If that doesn't work, check whether the extension's developer has released an update. Chrome usually updates extensions automatically, but you can force a check by clicking the puzzle-piece icon, then the three dots in the top right of the extensions menu, and selecting "Update extensions." If an update is available, it will install when ready.
If the extension still isn't working, visit its page in the Chrome Web Store and read the recent reviews. Other users often report problems there, and the developer sometimes posts fixes or explanations. If many people are reporting the same issue, the extension may be abandoned or incompatible with your version of Chrome. In that case, you may need to find a different tool that does the same job.
Keeping your extensions safe
Extensions can be powerful tools, but they also have access to your data. Stick to extensions from developers you recognize or that have thousands of positive reviews. Read the reviews before installing — if people are complaining that an extension is stealing data, selling their information, or showing unwanted ads, don't install it.
Check your installed extensions occasionally and remove ones you no longer use. The fewer extensions running, the less data you're exposing and the faster your browser will be. If you notice an extension suddenly asking for new permissions, that's worth investigating — click on it and read what changed.
Be especially careful with extensions that handle sensitive information, like password managers or banking tools. These should come from well-known companies with strong reputations. If you're unsure whether an extension is trustworthy, search for its name plus "scam" or "malware" to see if security researchers have flagged it.
Frequently Asked Questions
Can I use the same extensions on multiple devices?
Yes, if you sign into Chrome with the same Google account on multiple computers. Your extensions sync automatically across devices, and your settings come with them. If you want different extensions on different devices, you can manage them separately by signing out and back in with different accounts, or by disabling extensions on specific devices.
Why is an extension asking for permission to see all my data?
Some extensions genuinely need broad access to work — password managers, ad blockers, and grammar checkers all have to see what's on every page. Others ask for more permission than they actually need, which is a reason to be cautious. Read the extension's description and reviews to understand why it needs that access, and consider whether you trust the developer.
What happens to my extension data if I uninstall it?
When you remove an extension, Chrome deletes all the data it stored — saved settings, notes, lists, anything it created. If you reinstall it later, you'll start fresh. Some extensions let you export your data before you remove them, so check the extension's menu or settings if you want to save anything important.
Can I use extensions in 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, but you cannot install third-party extensions. If you need extension features on your phone, you may need to use a different browser or find a mobile app that does the same job.
How do I know if an extension is slowing down my browser?
Open Chrome's task manager by pressing Shift+Esc on Windows or Command+Shift+Esc on Mac. This shows you how much memory and CPU each extension is using. If one extension is using significantly more resources than others, try disabling it and see if your browser feels faster. You can also check the extension's reviews to see if other people report performance problems.
