Stop Your Browser From Tracking You: 5 Settings to Tweak Right Now

Your browser knows more about you than you might realize—where you click, what you type, which sites you visit, even how your screen is sized. Much of that data is collected automatically by default, feeding advertisers, analytics companies, and data brokers. While you can’t stop all tracking without breaking the web, adjusting a handful of settings will drastically reduce how much your browser leaks. A recent article from PCWorld highlighted exactly this problem, calling browsers “too nosy” and recommending five changes. Here’s what you need to know and do.

What Happened

PCWorld published a guide on June 11, 2026, titled “Your browser is too nosy. Change these 5 settings now.” The article walks through adjustments for Chrome, Firefox, Edge, and Safari that limit data collection. It points out that many users never touch these settings, leaving themselves exposed to cross-site tracking, browser fingerprinting, and unnecessary permission grants. The guide is short and practical—no jargon, just steps.

Why It Matters

Online tracking has grown more sophisticated in recent years. Even if you clear cookies regularly, techniques like fingerprinting can identify your device based on browser version, installed fonts, screen resolution, and other subtle traits. Meanwhile, browser vendors keep shifting privacy controls around. Google, for instance, is phasing out third-party cookies in Chrome (a process that has been delayed multiple times and may change again). But cookie blocking alone isn’t enough. The five settings in the PCWorld article address the bigger picture: stopping the most invasive forms of data collection without breaking normal site functionality.

Another reason this matters now: recent browser updates have reset or relocated privacy controls, so even if you changed something a year ago, it might no longer be active. Taking a few minutes to check these settings can restore protection that you thought was already in place.

What Readers Can Do

Below are the five settings recommended in the PCWorld article, along with how to find them in major browsers. I’ve added a few notes based on my own testing and what has changed since the article published.

1. Disable Third-Party Cookies (or Block All)

This is the most well-known privacy tweak, but the exact location varies.

  • Chrome: Go to Settings → Privacy and security → Third-party cookies. Select “Block third-party cookies.” Note: Chrome is gradually moving to a “Tracking Protection” mode that blocks third-party cookies by default, but as of mid-2026 this is still rolling out.
  • Firefox: Settings → Privacy & Security → Enhanced Tracking Protection. Choose “Strict” to block most third-party cookies. Custom settings let you block all.
  • Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data. Toggle “Block third-party cookies.”
  • Safari: Preferences → Privacy → uncheck “Allow cross-site tracking.” Safari already blocks many third-party cookies by default, but verifying is wise.

Caveat: Some sites may break if you block all third-party cookies. Use the “Block in Incognito” or “Custom” options if needed.

2. Turn Off “Do Not Track” and Enable Global Privacy Control

“Do Not Track” (DNT) is largely ignored by advertisers. Instead, use the newer Global Privacy Control (GPC), which legally requires sites to honor opt-out signals in some jurisdictions (e.g., California, Colorado).

  • Chrome: Does not support GPC natively. You can use the extension “Global Privacy Control” (available in Chrome Web Store).
  • Firefox: Settings → Privacy & Security → Custom block list → check “Send websites a ‘Do Not Track’ signal that you don’t want to be tracked.” Also enable “Tell websites not to sell or share my data” (this is GPC).
  • Edge: Similar to Chrome; use the same extension.
  • Safari: GPC is not built in, but extensions like “Privacy Badger” include it.

PCWorld recommends disabling DNT because it can actually fingerprint you (since so few users enable it). GPC is far more effective.

3. Block Fingerprinting Scripts

Fingerprinting uses scripts to collect unique device attributes. Firefox is the only major browser to block fingerprinting out of the box.

  • Firefox: Already on by default in Strict mode. To confirm: Settings → Privacy & Security → Enhanced Tracking Protection → Strict.
  • Chrome, Edge, Safari: No native fingerprinting protection. Install the uBlock Origin extension (free) and enable “Prevent WebRTC from leaking local IP addresses” and similar settings. Privacy Badger also helps.

4. Disable Location, Camera, and Microphone by Default

Sites request access to these sensors for convenience, but many ask unnecessarily.

  • All browsers: Go to Settings → Privacy & Security → Site Permissions (or similar). Set Location, Camera, and Microphone to “Block” or “Ask (default).” Then only allow when you explicitly approve on trusted sites.

This setting alone stops a huge amount of passive data collection—especially location, which is often used for hyper-local ads even on sites that don’t need it.

5. Use Private Browsing or Container Tabs

Private/incognito mode doesn’t make you anonymous, but it prevents your history and cookies from being saved across sessions. For stronger isolation, Firefox offers Container Tabs.

  • Firefox: Install Multi-Account Containers extension. Create separate containers for different activities: one for shopping, one for social media, one for work. This limits tracking across unrelated sites.
  • Chrome, Edge, Safari: Use “Guest mode” or separate profiles for different purposes. In Safari, you can create different profiles (macOS Ventura and later) that keep cookies and history separate.

Bonus: Clear Cookies and Cache Regularly

Even with all these changes, data accumulates. Set a reminder to clear cookies and cache every month. In most browsers, you can do this in the privacy section and choose a time range (e.g., “Last hour” or “All time”).

Settings paths checked in browser versions Chrome 126, Firefox 128, Edge 126, and Safari 17.5 as of late June 2026. Some menu labels may shift in minor updates—if you don’t see an exact match, search the browser’s settings page for the key term (e.g., “cookies” or “tracking”).
