Are Browser Extensions Safe? How to Pick Them Carefully

Browser extensions add handy features such as ad blocking, password filling and translation. They also run inside your browser with wide access, which makes careful choice important.

Why they can be risky

Many extensions can read and change the pages you visit. A malicious or compromised one could capture passwords, track browsing or inject ads. Sometimes a popular extension is sold and later changed to include harmful code.

How to choose safely

• Install only from the official store of your browser.
• Check the number of users, ratings and recent reviews.
• Read what permissions it asks for. Does a color picker need access to all websites?
• Look up the developer and a privacy policy.
• Prefer extensions that are open source or well known.

Keep your list short

Every extension is another thing to trust. Remove those you do not use, and disable them rather than leaving them active.

Review regularly

Open the extensions page every few months. Watch for any that changed owners or asked for new permissions.

Warning signs

Your homepage or search engine changed on its own, you see new pop-ups, or the browser is suddenly slow. Remove the latest extensions and run a security scan.

A small, well-chosen set of extensions gives you the benefits with limited risk.
