Your Browser Is Too Nosy: 5 Settings to Change Now

Your browser collects more data about you than you probably realize. Every site you visit, every search you run, and even how you move your mouse can be logged and shared with advertisers, analytics companies, and sometimes data brokers. While browsers have added privacy features over the years, most of them are turned off by default. The good news is that you can make a few simple changes to limit what your browser reveals—without needing technical skills.

Below are five settings you should check in Chrome, Firefox, or Edge. The exact menu labels may shift as browsers update, but the general paths should still be close.

What happened

Browser tracking isn’t new, but it has become more aggressive. Third-party cookies, location pings, and fingerprinting scripts are common ways sites identify and follow you across the web. Meanwhile, browsers continue to update their privacy controls, so settings you might have ignored a year ago may now be more effective—or harder to find. Recent moves by Google to phase out third-party cookies in Chrome show that the industry is shifting, but tracking methods like fingerprinting remain widespread.

Why it matters

When your browser collects and shares your activity data, it enables targeted advertising, personalized pricing, and sometimes even profiling. Even if you aren’t worried about ads, that same data can be exposed in a breach or used by third parties in ways you didn’t agree to. Taking a few minutes to adjust these settings significantly reduces the amount of information your browser leaks without harming your browsing experience.

What readers can do

1. Disable third-party cookies
Cookies themselves aren’t evil, but third-party cookies are the main tool advertisers use to track you across different websites.

  • Chrome: Go to Settings > Privacy and security > Third-party cookies. Select “Block third-party cookies” (or “Block all third-party cookies” if you prefer).
  • Firefox: Open Settings > Privacy & Security > Enhanced Tracking Protection. Set it to “Strict” which blocks third-party cookies by default.
  • Edge: Navigate to Settings > Cookies and site permissions > Manage and delete cookies and site data. Turn on “Block third-party cookies.”

Note: Chrome has been gradually phasing out third-party cookies for some users, but the setting still works for now.

2. Turn off location tracking
Many websites request your location even when they don’t need it. Blocking this globally prevents unnecessary alerts and keeps your physical location private.

  • Chrome: Settings > Privacy and security > Site Settings > Location. Choose “Don’t allow sites to see your location.”
  • Firefox: Settings > Privacy & Security > Permissions > Location. Check “Block new requests asking to access your location.”
  • Edge: Settings > Cookies and site permissions > Location. Turn off “Ask before accessing.”

You can always grant location to specific sites (like maps) later if needed.

3. Block browser fingerprinting
Fingerprinting uses your screen resolution, installed fonts, time zone, and dozens of other details to create a unique identifier that persists even without cookies. Firefox has a built-in anti-fingerprinting feature that many users don’t know about.

  • Firefox: Type about:config in the address bar, accept the warning, then search for privacy.resistFingerprinting. Double-click to set it to true. This also makes you look more like other Firefox users, reducing uniqueness.
  • Chrome and Edge: Neither has a dedicated fingerprinting toggle. Use an extension like uBlock Origin (see bonus below), which includes anti-fingerprinting filters.

4. Enable a Do Not Track signal (or Global Privacy Control)
Do Not Track (DNT) is a voluntary signal that tells websites you don’t want to be tracked. Unfortunately, many sites ignore it. Still, it costs nothing to turn on, and some privacy-respecting sites honor it. Newer browsers also support Global Privacy Control (GPC), which is legally binding in some jurisdictions.

  • Chrome: Settings > Privacy and security > Third-party cookies. Turn on “Send a ‘Do Not Track’ request with your browsing traffic.”
  • Firefox: Settings > Privacy & Security > Enhanced Tracking Protection. Check “Send websites a ‘Do Not Track’ signal.”
  • Edge: Settings > Privacy, search, and services > Personalization & ads. Turn on “Send Do Not Track requests.”

5. Clear browsing data automatically on exit
Auto-clearing cookies, cache, and history ensures no residual data sticks around after you close the browser. This is especially useful if you share a computer, but it also stops long-term tracking from persistent storage.

  • Chrome: Settings > Privacy and security > Clear browsing data > Advanced. Choose “Cookies and other site data” and “Cached images and files.” Then enable “Clear data when you close all windows.”
  • Firefox: Settings > Privacy & Security > History. Under “Firefox will,” select “Use custom settings.” Check “Clear history when Firefox closes,” then click Settings to pick what to clear (cookies, cache, etc.).
  • Edge: Settings > Privacy, search, and services > Clear browsing data. Turn on “Choose what to clear every time you close the browser.” Select the items you want cleared.

Bonus: Use a content blocker
For additional protection, install uBlock Origin on Firefox (it still works fully there) or a similar blocker on Chrome and Edge. It blocks many trackers, ads, and fingerprinting scripts that escape browser settings. On Chrome, note that Manifest v3 restrictions will eventually limit uBlock Origin’s functionality; consider using Firefox or Brave if that matters to you.

The steps above reflect current browser versions as of mid‑2026. Because browsers update frequently, you may need to search for exact wording inside settings. The key is to look for the options described—they are almost always available, just sometimes moved.
