Your Browser Is Too Nosy: 5 Settings to Stop Tracking Now (Easy Changes)

Introduction

Your web browser knows more about you than you probably realize. Every site you visit, every search you make, and even how long you hover over a link gets recorded by default in most major browsers. That data is used for ad targeting, profiling, and sometimes shared with third parties you’ve never heard of.

The good news is you don’t need to be a tech expert to lock things down. Below are five straightforward changes you can make in Chrome, Firefox, Edge, or Safari to significantly reduce how much your browser shares about you. None of these changes require installing extra software, though we’ll mention a couple of extensions if you want to go further.

What Happened

Browser companies have been quietly expanding how they collect and use your data. Google’s Chrome Privacy Sandbox, for example, replaced third-party cookies with new tracking methods that still allow advertisers to profile you. Firefox and Edge have improved their privacy features, but they still send telemetry data back to their parent companies by default. Safari’s Intelligent Tracking Prevention helps, but it doesn’t block every tracking attempt.

Recent updates to these browsers have made some privacy settings easier to find—but they’re still not turned on out of the box. That’s the gap this guide is meant to close.

Why It Matters

When your browser tracks you, it’s not just about seeing more relevant ads. Data brokers use browsing history and behavioral patterns to build detailed profiles that can influence loan approvals, insurance rates, or even job prospects. Telemetry data, while often anonymized, can still be linked back to your device. And fingerprinting—where sites identify your unique combination of browser version, screen size, fonts, and installed plugins—is harder to block than cookies.

These settings won’t make you invisible online, but they will cut out the most common channels companies use to follow you around the web.

What Readers Can Do

Here are five changes to make, in roughly the order of impact.

1. Block Third-Party Cookies and Cross-Site Trackers

Third-party cookies are the main way advertisers track you across different websites. All major browsers now offer a way to block them.

  • Chrome: Go to Settings > Privacy and security > Third-party cookies. Select “Block third-party cookies.”
  • Firefox: Settings > Privacy & Security > Enhanced Tracking Protection. Choose “Strict” (this also blocks trackers and cryptominers).
  • Edge: Settings > Privacy, search, and services > Tracking prevention. Select “Strict” mode.
  • Safari: Safari > Settings > Privacy. Check “Prevent cross-site tracking.” Safari also hides your IP address from known trackers by default in newer versions.

Be aware that blocking all third-party cookies may break some sites or prevent certain logins (like “Login with Google”). You can usually allow exceptions on a per-site basis.

2. Turn Off Browser Telemetry and Crash Reports

Browsers send usage data back to their developers. This includes which features you use, how often, and sometimes error details. It’s rarely needed for normal operation.

  • Chrome: Settings > Privacy and security > Sync and Google services. Turn off “Help improve Chrome’s features and performance.” Also disable “Make searches and browsing better” under the same section.
  • Firefox: Settings > Privacy & Security > Firefox Data Collection and Use. Uncheck all boxes.
  • Edge: Settings > Privacy, search, and services > Personalization & advertising. Turn off “Improve your browsing experience” and disable “Help improve Microsoft products” under Diagnostics & feedback.
  • Safari: Safari > Settings > Advanced. Uncheck “Include website icons in tabs,” but there’s no direct telemetry toggle on macOS. On iOS, go to Settings > Privacy & Security > Analytics & Improvements and disable Share iPhone Analytics.

Disabling telemetry won’t affect your browsing, and you can still receive security updates.

3. Disable Ad Personalization and Interest-Based Advertising

Even without cookies, browsers often use your history to serve tailored ads. This setting is often separate from cookie controls.

  • Chrome: Settings > Privacy and security > Ads privacy. Under “Ad topics,” turn off. Also disable “Site-suggested ads” and “Ad measurement.”
  • Firefox: Type about:preferences#privacy in the address bar. Under “Permissions,” click Settings next to “Permissions for websites to serve ads.” Uncheck the box.
  • Edge: Settings > Privacy, search, and services > Advertising. Turn off “Show me personalized ads.”
  • Safari: On macOS, go to System Settings > Privacy & Security > Apple Advertising and uncheck “Personalized Ads.” On iOS, Settings > Privacy & Security > Apple Advertising.

This reduces the number of ads that follow you across the web based on your recent searches.

4. Reduce Fingerprinting Information

Fingerprinting works by collecting many small details about your browser—like your installed fonts, screen resolution, time zone, and language—to create a unique “fingerprint.” There’s no single switch to stop it, but you can make it harder.

  • Firefox: Go to Settings > Privacy & Security > Enhanced Tracking Protection. Choose “Strict” mode, which includes fingerprinting blocking.
  • Chrome, Edge, Safari: These browsers don’t have a built-in fingerprinting blocker. You can install an extension like Privacy Badger (from the EFF) or uBlock Origin, which block many fingerprinting scripts. Note that Manifest v3 changes in Chrome may weaken some extensions over time.
  • General tip: Avoid installing unnecessary browser extensions; each one adds more data points that can be used for fingerprinting.

No browser setting can fully prevent fingerprinting, but reducing the number of unique identifiers lowers your profile value to trackers.

5. Be Careful with Built-in VPNs and Proxies

Some browsers now include free VPN or proxy features. Edge has Edge Secure Network, and Opera offers a built-in VPN. These are not the same as a paid, reputable VPN service.

  • Edge Secure Network uses Cloudflare and caps data at 1 GB per month. It hides your IP from sites but doesn’t anonymize you from Microsoft.
  • Opera’s free VPN has been criticized for logging and is not a full VPN—it’s a proxy that only works within the browser.

If you need IP hiding, a paid VPN that doesn’t log (such as Mullvad or ProtonVPN) is more trustworthy. The free browser offerings are better than nothing for occasional use, but they come with trade-offs. In most cases, simply blocking trackers and using DNS-over-HTTPS (doH) provides enough privacy for everyday browsing.
