How to add extensions to Chrome

Open Chrome and go to the Chrome Web Store at chromewebstore.google.com. Search for the extension you want — for example, "password manager" or "ad blocker" — and click the extension name in the results. On the extension's page, click the blue "Add to Chrome" button. A popup will appear asking you to confirm; click "Add extension" again. The extension will install immediately and usually appear as a small icon in your toolbar at the top right of the browser window.

Some extensions ask for permission to read or change data on websites you visit. Chrome will show you exactly what the extension wants access to before you confirm the install. Read this list carefully — if an extension asks for more access than it needs (for example, a weather app asking to read all your emails), you can decline and look for a different one instead.

Key Takeaways

  • The Chrome Web Store is the official place to find and install extensions; avoid downloading them from other websites.
  • Always read what permissions an extension is asking for before you click "Add extension" — this tells you what data it can access.
  • You can turn extensions on or off, remove them entirely, or limit what websites they work on through Chrome's extension settings.
  • If an extension stops working or causes problems, you can uninstall it and reinstall a fresh copy from the Web Store.

Finding extensions that match what you need

The Chrome Web Store sorts extensions by category: productivity, shopping, news, security, and others. You can browse by category or search by name. Look at the star rating and read a few recent user reviews before you install — these often mention if the extension works well, if it slows down your browser, or if it has stopped being updated.

Pay attention to when the extension was last updated. If the last update was more than a year ago and the extension has few recent reviews, it may no longer work properly or may have security issues. Extensions from well-known companies (like Grammarly, LastPass, or uBlock Origin) tend to be updated regularly because the companies behind them maintain them actively.

Understanding what permissions mean

When you click "Add extension," Chrome shows you a list of permissions — things the extension is allowed to do. Common permissions include "read your browsing history," "see what you type," or "change settings on websites you visit." These permissions exist because some extensions genuinely need them to work. A password manager needs to see what you type so it can fill in passwords; an ad blocker needs to change what appears on websites.

The key is matching the permission to the job. A simple note-taking extension should not need to read your browsing history. A screenshot tool should not need access to your passwords. If the permissions seem wrong for what the extension claims to do, close the page and search for a different extension instead. You are not being paranoid — you are being careful about what software can access.

Managing extensions you already have installed

Click the puzzle-piece icon in the top right corner of Chrome (or the three vertical dots menu, then "Extensions," then "Manage extensions"). This page shows every extension you have installed, whether it is turned on or off, and when it was last updated. You can toggle any extension on or off with the switch next to its name — turning it off stops it from running but keeps it installed, so you can turn it back on later without reinstalling.

Next to each extension is a three-dot menu. Click it to see options like "Remove from Chrome" (which uninstalls it completely), "Manage extension," or "Report abuse." The "Manage extension" page for each one lets you control which websites the extension can access — you can set it to run on all websites, only on certain sites, or only when you click its icon.

Limiting what websites an extension can access

By default, many extensions can run on every website you visit. You can change this to protect your privacy. Go to the extension's manage page (puzzle-piece icon, then the three-dot menu next to the extension, then "Manage extension"). Look for the section labeled "Site access" or "Permissions." You will see options like "On all sites," "On specific sites," or "On click only."

Choose "On click only" if you want the extension to do nothing unless you click its icon. Choose "On specific sites" if you want it to work only on certain websites — for example, a grammar checker might only need to run on Gmail and Google Docs, not on every page you visit. This approach reduces the amount of data the extension can see and gives you more control over when it runs.

Removing extensions you no longer use

Click the puzzle-piece icon in the top right, find the extension you want to remove, click the three-dot menu next to it, and select "Remove from Chrome." A confirmation popup will appear; click "Remove" again. The extension is now uninstalled and will no longer run. If you change your mind later, you can reinstall it from the Chrome Web Store — your settings will not be saved, but the extension itself will work the same way.

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 down your browser slightly. If you have not used an extension in weeks, uninstalling it will make Chrome run a bit faster and reduce the number of programs that can access your data.

What to do if an extension stops working

First, check if the extension is turned on. Go to the puzzle-piece icon and look for the extension in the list — if the toggle switch is off, turn it back on. If it is already on, try turning it off and back on again; this often fixes temporary glitches. If that does not work, uninstall it (three-dot menu, "Remove from Chrome") and reinstall it fresh from the Chrome Web Store.

If reinstalling does not fix it, check the extension's page in the Chrome Web Store — scroll down to read recent reviews to see if other people are reporting the same problem. If many people mention the extension is broken, the developer may be working on a fix or may have abandoned the project. In that case, search the Web Store for a similar extension from a different developer. If the extension worked fine yesterday and suddenly stopped, your browser may need an update; restart Chrome completely and try again.

Frequently Asked Questions

Is it safe to install extensions from the Chrome Web Store?

Google reviews extensions before they appear in the Web Store, but that does not mean every extension is safe or trustworthy. Stick to extensions from well-known companies or those with many positive recent reviews. Read the permissions carefully — if something seems wrong, do not install it. The Web Store is safer than downloading extensions from random websites, but your own judgment matters too.

Can an extension see my passwords or banking information?

Only if you give it permission to. When you install an extension, Chrome tells you exactly what it can access. A password manager needs to see passwords to fill them in; most other extensions should not ask for this. If an extension requests access to sensitive data and does not need it for its job, decline the install and find a different one.

Why is my browser slower after I installed extensions?

Each extension running in the background uses memory and processing power. If you have many extensions installed, they can add up. Go to the puzzle-piece icon and uninstall extensions you do not use regularly. Turn on "On click only" for extensions you only need sometimes. This will free up memory and speed up your browser.

What happens if I turn off an extension?

Turning off an extension stops it from running, but it stays installed on your computer. You can turn it back on anytime by clicking the toggle switch again. Your settings for that extension are saved, so when you turn it back on, it will work exactly as you left it.

Can I use the same extension on multiple computers?

Yes. If you sign into Chrome with your Google account on another computer, your extensions will automatically install on that computer too. Your settings and data for each extension will sync across devices if the extension supports syncing — check the extension's page to see if this feature is available.
