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," or go to chromewebstore.google.com in your address bar.

The Web Store shows you what each extension does before you install it. You see screenshots, user reviews, the number of downloads, and what data the extension can access on your computer. Read the permissions section carefully — an extension that changes your search engine needs different access than one that blocks ads.

Not every tool you find online is in the Web Store. Some developers sell extensions elsewhere or distribute them privately. Those require a different installation method, which we cover below. Stick with the Web Store for your first extensions; everything there has passed Google's basic safety checks.

Key Takeaways

  • The Chrome Web Store is built into your browser — click the puzzle-piece icon and select "Open Chrome Web Store" to browse.
  • Installing an extension takes one click on the "Add to Chrome" button, and you see what data it can access before you confirm.
  • Your installed extensions appear in the puzzle-piece menu, where you can turn them on and off without uninstalling them.
  • You can manage extension permissions in Settings so an extension cannot access all your tabs or all your websites.
  • Extensions from outside the Web Store require manual installation and carry more risk, so start with the official store.

Installing an extension in three steps

Search the Web Store for what you need — "password manager," "ad blocker," "grammar checker" — and click on the extension you want. Read the description and reviews to make sure it does what you need. Then click the blue "Add to Chrome" button.

A popup appears asking you to confirm. It lists what the extension can do: "Read and change your data on all websites" or "See your browsing history" or "Manage your downloads." Read this list. If it seems like too much access for what the tool claims to do, go back and pick a different one. Click "Add extension" to finish.

The extension installs when ready. You see a confirmation message, and the puzzle-piece icon in your toolbar lights up. Some extensions add their own button next to the puzzle piece for faster access. You are ready to use it.

Turning extensions on, off, and managing what they can see

Click the puzzle-piece icon to see all your installed extensions. Each one has three dots next to its name. Click those dots to see your options: "Remove from Chrome" deletes it, and "Manage extension" opens its settings page.

In the manage page, you control what websites the extension can access. By default, most extensions can see every website you visit. You can change this to "On click only" (so it works only when you click its button), "On specific sites" (so you choose which ones), or "On all sites" (the default). This is where you lock down privacy — an extension that reads your email does not need to see your banking site.

You can also turn an extension off temporarily without removing it. In the puzzle-piece menu, toggle the switch next to its name. The extension stays installed but does nothing until you turn it back on. This is useful if an extension slows down your browser or conflicts with another tool.

Installing extensions from outside the Web Store

Some developers distribute extensions outside the official store. These might be beta versions, tools for specific companies, or extensions that do not meet Google's policies. Installing one requires you to read a file and add it manually.

Go to chrome://extensions in your address bar. Toggle "Developer mode" on in the top right corner. Then drag and drop the extension file onto this page, or click "Load unpacked" and select the folder containing the extension. Chrome installs it and adds it to your puzzle-piece menu.

Extensions installed this way do not update automatically. You have to check for updates yourself or reinstall the file when the developer releases a new version. Use this method only for extensions you trust completely, because Google has not reviewed them for safety.

What to do if an extension stops working

Extensions sometimes break after a Chrome update or when a website changes its design. First, try turning the extension off and back on. Go to the puzzle-piece menu, toggle it off, wait a few seconds, and toggle it back on.

If that does not work, check the extension's settings page. Click the three dots next to its name and select "Manage extension." Look for a "Details" or "About" section that might explain what went wrong. Some extensions show error messages here.

If the extension still does not work, uninstall it and reinstall it fresh. Click the three dots, select "Remove from Chrome," then go back to the Web Store and add it again. This clears out any corrupted settings. If it still fails, the extension may no longer be maintained — check the reviews to see if other people report the same problem, and consider switching to a different tool.

Keeping extensions safe and your browser fast

Only install extensions you actually use. Each one runs in the background and uses memory and battery power, even if you are not actively using it. If you have not clicked an extension in a month, uninstall it.

Check your installed extensions every few months. Go to the puzzle-piece menu and look at what you have. Remove anything you forgot about or no longer need. This keeps your browser fast and reduces the number of tools that can see your browsing data.

Read the reviews before installing anything. If an extension has hundreds of downloads but mostly one-star reviews, skip it. Look for recent reviews — an extension that worked fine two years ago might be broken now. If the developer has not updated it in over a year, that is a sign they have abandoned it.

Frequently Asked Questions

Can I use the same extension on multiple computers?

Yes. Sign into your Google account on each computer, and Chrome syncs your extensions across all of them. Your settings and preferences sync too, so the extension works the same way on every device. If you turn an extension off on one computer, it turns off on all of them.

What does it mean when an extension asks for permission to "read and change your data on all websites"?

It means the extension can see the content of every webpage you visit and modify what you see on the screen. Password managers need this to fill in login forms. Ad blockers need it to hide ads. If an extension asks for this permission but does not need it for its job, that is a red flag — uninstall it and find a different one.

Will an extension slow down my browser?

Most extensions have a small impact, but some are heavy. If your browser feels slow after installing something, try turning off the extension and see if speed improves. If it does, the extension is the problem — either adjust its settings to use less access, or uninstall it and try a lighter alternative.

Can I move an extension's button to a different spot in my toolbar?

Yes. Right-click any extension button and select "Show in toolbar" or "Hide in toolbar" to control which ones appear. You can also drag extension buttons left and right to reorder them. This helps you keep your toolbar clean and puts your most-used tools front and center.

What happens to my extensions if I uninstall Chrome?

They are removed from your computer, but they stay linked to your Google account. When you reinstall Chrome and sign in, your extensions read and reinstall automatically. Your settings come back too, so you do not have to set everything up again.
