Browser Privacy Settings You Should Change Today

Your browser is the primary tool through which the internet tracks you. Every website visit, every search, every click can be logged, profiled, and sold to advertisers. The default settings of most browsers prioritize convenience over privacy. Changing a few settings — which takes under 10 minutes — dramatically reduces your exposure.

Browser privacy is part of our complete digital privacy guide. This article provides the specific settings to change right now.

Step 1: Install uBlock Origin

This is the single highest-impact privacy extension. uBlock Origin (free, open-source) blocks ads, trackers, and malicious scripts. It reduces page load times, saves bandwidth, and eliminates approximately 80% of web tracking. Install it from your browser’s extension store — takes 30 seconds.

Do not confuse it with “uBlock” (without “Origin”) — the original project was taken over and the developer created uBlock Origin as the legitimate continuation.

Step 2: Change Your Default Search Engine

DuckDuckGo: Does not track searches, does not build advertising profiles, does not filter results based on your history. The search quality has improved dramatically and is sufficient for 90%+ of searches. Set it as your default in browser settings.

When you need Google’s results specifically, you can always navigate to google.com directly. But making DuckDuckGo the default means your routine searches are not being profiled.

Step 3: Browser-Specific Settings

Firefox: Settings → Privacy & Security → Enhanced Tracking Protection: set to Strict. Enable “Delete cookies and site data when Firefox is closed.” Disable “Allow Firefox to send technical data.” These three changes put Firefox in a strong privacy posture.

Chrome: Settings → Privacy and Security → Third-party cookies: Block. Clear browsing data: enable “Clear cookies on exit.” Disable “Help improve Chrome features.” Note: Chrome is made by Google and has inherent tracking limitations. For serious privacy, switch to Firefox or Brave.

Brave: Privacy settings are strong by default. Verify: Shields are set to Aggressive. Fingerprinting protection is enabled. Cross-site cookie blocking is on. Brave is the easiest browser for privacy — most settings are correct out of the box.
