Your Browser is Too Nosy: 5 Privacy Settings to Change Now

Your web browser collects more data about you than you might realize—sites you visit, how long you stay, where you click, even your approximate location. A recent PCWorld article highlighted how browsers by default often share this information with advertisers, analytics companies, and other third parties. The good news is that a few simple setting changes can significantly reduce tracking without breaking most websites.

The settings below are available in Chrome, Firefox, Edge, and Safari, though the exact menu labels may differ slightly. If you make a change and a site stops working properly, you can always revert it or add an exception for that specific site.

1. Disable Third-Party Cookies and Cross-Site Tracking

Third-party cookies are the main tool advertisers use to follow you across the web. Every browser now offers 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 “Custom” and check “Cookies” then select “Cross-site tracking cookies.”
  • Edge: Settings > Cookies and site permissions > Manage and delete cookies and site data. Toggle on “Block third-party cookies.”
  • Safari: Safari’s Intelligent Tracking Prevention is on by default. To tighten further, go to Safari > Settings > Privacy and check “Prevent cross-site tracking.”

Be aware that some websites that rely on third-party cookies for login widgets or embedded content may behave differently. You can always whitelist specific sites if needed.

2. Turn Off Location Tracking

Many sites ask for your precise location when you first visit. Even if you deny the request, your IP address can still give an approximate area. Browsers can block geolocation requests entirely.

  • Chrome: Settings > Privacy and security > Site Settings > Location. Select “Don’t allow sites to see your location.”
  • Firefox: Settings > Privacy & Security > Permissions > Location. Click “Settings” and uncheck “Block new requests asking to access your location” (or set to “Blocked” globally).
  • Edge: Settings > Cookies and site permissions > Location. Toggle off “Ask before accessing.”
  • Safari: Safari > Settings > Websites > Location. Set to “Deny” for all websites.

If you use maps or navigation sites, you can allow location on a case-by-case basis in your browser’s site permissions.

3. Block Pop-Ups and Unwanted Redirects

Pop-ups are not just annoying—they can also be used for deceptive ads or phishing attempts. Modern browsers block most pop-ups by default, but it’s worth checking that the setting is active.

  • Chrome: Settings > Privacy and security > Site Settings > Pop-ups and redirects. Ensure it is set to “Don’t allow sites to send pop-ups or use redirects.”
  • Firefox: Settings > Privacy & Security > Permissions > Block pop-up windows. Make sure the checkbox is selected.
  • Edge: Settings > Cookies and site permissions > Pop-ups and redirects. Toggle on “Block.”
  • Safari: Safari > Settings > Websites > Pop-up Windows. Set to “Block.”

Some legitimate sites (like banking portals or web-based apps) do need pop-ups. You can temporarily allow them when needed.

4. Enable Strict Content Blocking or Tracker Protection

All major browsers now include built-in protection against known trackers, fingerprinting scripts, and cryptominers. Enabling the strictest level gives a meaningful privacy boost.

  • Chrome: Settings > Privacy and security > Security. In “Enhanced protection” mode, Chrome blocks dangerous sites and scans for suspicious downloads. This also includes some anti-tracking features.
  • Firefox: Settings > Privacy & Security > Enhanced Tracking Protection. Choose “Strict” mode, which blocks trackers, fingerprinters, and cryptominers.
  • Edge: Settings > Privacy, search, and services > Tracking prevention. Set to “Strict.”
  • Safari: Safari’s intelligent tracking prevention is always on. For additional protection, go to Safari > Settings > Privacy and check “Hide IP address from trackers.”

The strictest setting may break some website functions (e.g., social media share buttons or embedded videos). If something doesn’t work, try switching to a less aggressive level or adding exceptions.

5. Turn Off Personalized Ads and Ad Personalization Settings

Browsers and their associated accounts (Google, Microsoft, Apple) often use your browsing history to serve personalized ads. You can disable this.

  • Chrome (Google account): Go to myadcenter.google.com and turn off “Ad personalization.” Also in Chrome settings, go to Privacy and security > Ad privacy. Review and disable the three topics: Ad topics, Site-suggested ads, and Ad measurement.
  • Firefox: Firefox does not serve personalized ads, but it does have a setting in Settings > Privacy & Security > Permissions that controls “Website advertising preferences.” Uncheck “Tell websites I do not want my data collected for ad targeting.”
  • Edge (Microsoft account): Go to account.microsoft.com/privacy/ad-settings and turn off “See personalized ads.” In Edge settings, go to Privacy, search, and services > Personalization & advertising and turn off “Let advertisers use my personal information for personalized ads.”
  • Safari (Apple account): On your iPhone or Mac, go to Settings/System Settings > Privacy & Security > Apple Advertising and turn off “Personalized Ads.”

Disabling personalization does not remove ads entirely, but it stops them from being tailored to your recent browsing behavior.

Additional Steps for Better Privacy

Beyond the five settings above, consider enabling HTTPS-Only Mode (available in Firefox and Edge, and automatic in Chrome and Safari). This forces the browser to use encrypted connections whenever possible.

Regularly clear your browsing history and cookies—at least every few weeks. Most browsers allow you to auto-clear this data when you close the browser.

For an extra layer, consider privacy-focused browser extensions like uBlock Origin (for blocking trackers and ads) or Privacy Badger from the Electronic Frontier Foundation. These can catch threats that built-in protections miss.

Each browser update may reset or change some settings, so it’s worth reviewing these options every few months. A few minutes of configuration can go a long way toward keeping your browsing habits private.
