1. Is your browser on its latest version (auto-update on)?

Yes No / Not sure

Chrome, Firefox, Edge, Safari all auto-update. Open about: and verify.

2. Have you reviewed installed extensions in the last 6 months?

Yes No / Not sure

Extensions can read everything you type. Prune to what you actually use.

3. Do you use a content blocker (uBlock Origin) or the browser's built-in tracker block?

Yes No / Not sure

Beyond ads: blocks known malicious domains and trackers.

4. Is HTTPS-only mode enabled?

Yes No / Not sure

Firefox and Chrome both support "HTTPS-only" that blocks plain HTTP pages.

5. Is the browser's Safe Browsing / anti-phishing protection on?

Yes No / Not sure

Chrome: Settings → Privacy → Safe Browsing. Firefox: equivalent under Privacy.

6. Do you use browser profiles to separate work and personal sessions?

Yes No / Not sure

Profile isolation contains compromise and reduces cross-site tracking.

Yes No / Not sure

Firefox and Safari block by default. Chrome has "Block third-party cookies" option.

8. Is autofill restricted to a password manager (not the browser's built-in)?

Yes No / Not sure

Browser autofill leaks credentials to malicious scripts. Use 1Password / Bitwarden instead.

9. Are unused browsers uninstalled from your device?

Yes No / Not sure

That dusty old Edge / Internet Explorer you never use is still a target.

10. Do you routinely clear cookies / site data for sites you don't return to?
