Browser extensions can block ads, manage passwords, improve shopping, change tabs and add useful AI tools. But an extension can also receive powerful permissions inside your browser. Before clicking Add to Chrome, Edge or Firefox, spend a minute checking what you are installing.
1. Read the permission request
Pay attention when an extension asks to read and change data on websites you visit. Some tools genuinely need broad access, but a simple extension should not automatically require permission to see everything you do online.
2. Check who publishes it
Look at the developer name and official website. For extensions tied to a known service, follow the extension link from the company’s official website when possible instead of trusting a similarly named listing.
3. Do not trust the star rating alone
A high rating is useful context, not proof of safety. Read recent reviews and look for complaints about unexpected ads, redirects, changed search engines, new permissions or features that suddenly stopped working.
4. Check when it was last updated
An old extension is not automatically unsafe, but abandoned software may miss security fixes or stop working correctly as browsers change. Look at its update history and whether the developer still supports it.
5. Ask whether you need an extension at all
Modern browsers already include password generation, translation, screenshots, tab organization, tracking protection and other tools. Using a built-in feature can eliminate another piece of software with access to your browser.
6. Remove extensions you stopped using
An extension you installed two years ago can remain active even if you have forgotten about it. Open your browser’s extension manager every few months and remove anything you no longer need.
7. Watch for permission changes after an update
Software can change ownership or add features. If an extension suddenly asks for significantly broader permissions, do not approve automatically. Check what changed first.
A simple rule
Treat browser extensions more like apps than bookmarks. Install fewer of them, keep the useful ones updated and periodically review their permissions. A two-minute cleanup can reduce clutter and unnecessary access to your browsing data.
