Chrome extensions are little add-ons that change what Chrome can do. Block ads. Save passwords. Translate pages. Strip ads from YouTube. The right 5 to 10 extensions can transform Chrome from a basic browser into a real productivity tool. The wrong ones slow your browser to a crawl or compromise your privacy.
Here is how to install, manage and stay safe with Chrome extensions in 2026.
Installing a Chrome Extension
Open Chrome and go to chromewebstore.google.com. Search for the extension you want by name or browse by category. Click on the extension card to see details, screenshots and reviews. Click Add to Chrome. A popup shows what permissions the extension needs. Read them. Confirm if the permissions look reasonable for what the extension claims to do.
The extension icon appears in the top right corner of Chrome after installation. For extensions you use often, pin them by clicking the puzzle icon top right and clicking the pin next to the extension. Pinned extensions show their icons in the toolbar permanently.
Managing Extensions
The extension manager is where you control everything. Click the three dots in the top right > Extensions > Manage Extensions, or just type chrome://extensions in the address bar.
The manager shows all installed extensions. Each has a toggle to enable or disable it without uninstalling. Remove deletes it completely. Details shows the permissions, recent activity and configuration options. Review this page every few months. Disable or remove extensions you no longer use because each one slightly slows browser startup.
Best Chrome Extensions Worth Installing
The Chrome Web Store has hundreds of thousands of extensions. Most are forgettable. A handful are essential. These are the ones worth installing for almost any user.
- uBlock Origin Lite blocks ads efficiently on most sites. The successor to uBlock Origin under Chrome’s newer extension rules.
- 1Password or Bitwarden serves as your password manager extension for autofilling logins.
- Grammarly catches grammar and spelling issues in real time in Gmail, Docs and most text fields.
- Loom enables quick screen recording and sharing with a simple button.
- Save to Notion or Pocket lets you save pages for later reading or reference.
- DarkReader applies dark mode to every website automatically.
- Honey auto-applies coupon codes at online checkout to save money.
- Privacy Badger blocks third-party trackers without breaking sites.
How to Spot Bad Extensions
Not all extensions in the Web Store are trustworthy. Some are spyware in disguise. Some are scams. Knowing the warning signs saves you from data leaks.
Look at the user count first. Extensions with fewer than 1,000 users are higher risk. Check the ratings. Anything below 4 stars or with mostly recent negative reviews is suspicious. Vague developer names with no website are red flags. Look at what permissions are requested. If a simple tool wants to read all data on all sites with no clear reason, skip it. Copies of legitimate extension names (look for typos in the title) are common phishing patterns.
Understanding Extension Permissions
Each extension requests certain permissions when you install. Knowing what each one means helps you decide whether to trust the extension.
Read and change all your data on websites you visit is the most common and most powerful permission. The extension can see everything you do online. Trustworthy ones like password managers and ad blockers genuinely need it. Sketchy ones abuse it to steal data. Read your browsing history is used by recommendation extensions and some productivity tools. Less common than full data access. Display notifications is needed for alert-style extensions. Generally harmless. Manage your apps, extensions and themes is rare and powerful. Be very cautious with extensions requesting this.
Using Per-Site Permissions
For better privacy, you can restrict extensions to specific sites instead of letting them run everywhere. This is a big privacy win that most users miss.
Right-click the extension icon top right and find the option called This site can read and change site data. Change it to On click (so the extension only runs when you click it) or specific sites (where you list the sites where it can run). The extension still works but only on the sites you explicitly allow. Use this for extensions you want occasionally but not everywhere.
Syncing Extensions Across Devices
If you sign into Chrome with the same Google account on multiple devices, your extensions sync automatically. Settings > You and Google > Sync > Manage what you sync and make sure Extensions is on. The extensions install themselves on your other Chrome installations. Note that extension settings may not sync, just the list of installed extensions.
Mobile Chrome and Extensions
Chrome on iPhone and Android does not support extensions. This is a limitation of Chrome mobile. The workarounds are to use Kiwi Browser or Yandex Browser on Android, both of which support most desktop Chrome extensions. On iPhone, the equivalent is Safari Extensions which work differently and have a smaller library.
When Extensions Slow Chrome
Too many extensions slow Chrome down noticeably. Audit your extensions every 6 months. Remove ones you no longer use. Disable extensions in Incognito mode for cleaner private browsing. Use Chrome Task Manager (Shift + Esc) to see which extension is eating memory or CPU. The worst offenders are usually random screenshot tools or wallpaper extensions you installed and forgot about.
Final Thoughts
To use Chrome extensions effectively, install from the official Web Store, pin the ones you use often and audit permissions. Stick to extensions with millions of users from known developers. Use per-site permissions for better privacy. Remove ones you no longer use. Chrome becomes way more powerful with the right 5 to 10 extensions, but more is not better.
