How to Check and Harden Your Browser's Security Settings

Tap an item for a quick checklist to harden your browser's security settings.

Why you should keep automatic updates turned on

Browser makers regularly release updates specifically to close newly discovered security holes, so turning off automatic updates leaves you exposed to vulnerabilities that are already publicly known.

Why an unnecessary extension can be a security risk

Many extensions request permission to read or modify the content of every page you visit, so installing an unverified one can expose your browsing history or the information you type.

What the unsafe-site warning feature actually does

Most browsers automatically display a warning screen when you try to visit a known phishing or malware site, so leave this feature turned on rather than disabling it.

How to manage saved passwords and autofill data

Periodically review the passwords and card details saved in your browser, delete entries for accounts you no longer use, and avoid saving anything at all on a shared or public computer.

Review per-site permissions for location, camera, and notifications

Location, camera and microphone, and notification permissions accumulate across the many sites you've visited, so checking your browser settings periodically and revoking anything no longer needed helps protect your privacy.

Understanding the limits of private (incognito) mode

Private browsing only avoids saving your history and cookies locally on your device β€” it doesn't hide you from your internet provider or from the websites you visit, so don't mistake it for a complete anonymity tool.

A browser is the front door to almost everything you do online

Since so much online activity flows through a browser, checking its security settings properly can head off a lot of threats before they happen. A few settings checked regularly go a long way compared to leaving the defaults untouched.

A synced account carries real convenience β€” and real exposure

Signing into a browser account to sync saved passwords, bookmarks, and history across devices is genuinely convenient, but it also means that if that account is ever compromised, everything synced to it is exposed at once. Using a strong, unique password and enabling two-factor authentication on your browser account is worth treating with the same seriousness as any other important account.

Frequently Asked Questions

How many extensions is it safe to have installed?

The number itself matters less than what permissions each extension asks for and how trustworthy its developer is β€” remove anything you're not actively using and keep only what you genuinely need.

If my browser security settings are solid, do I still need antivirus software?

Browser security settings reduce threats that arrive through the web, but they don't stop malware coming through other routes, like an email attachment or a USB drive, so it's safer to use them alongside antivirus software.
