Think your antivirus is enough? If your browser isn’t secure, your data, and even your logins, could be at risk. Luckily, tightening things up takes just a few minutes. Here’s how:

How to lock things down (Chrome example):

– Click the three dots in the top right, then go to Settings.
– Select Privacy and Security.
– Turn on Enhanced Protection under Safe Browsing — this gives you faster, smarter protection from phishing, dodgy sites, and harmful downloads.
– Go to Cookies and other site data, and choose Block third-party cookies for more private browsing.
– Scroll to Site Settings, then:
– Block pop-ups (unless you really need them).
– Disable camera and microphone access unless needed.
– Check permissions for location, notifications, and clipboard, and switch off anything that looks unnecessary.

Bonus steps:

– Install a reputable ad blocker (e.g. AdGuard – there are many others).
– Use a password manager instead of letting your browser save logins.
– Make sure automatic updates are enabled so you’re always running the latest security fixes.

Pro-Tip: These steps apply to most major browsers – Firefox, Edge and Brave all have similar privacy and security menus. Just search for Privacy settings in their menus and follow the same logic.
