Stop Your Browser From Tracking Everything You Do: 5 Settings You Should Change Right Now

Your web browser knows more about you than you probably realize. Every site you visit, every search you type, and every product you linger on gets recorded—often shared with advertisers and data brokers by default. The good news: you don’t need to be a tech expert to take back some control. Changing a handful of settings in Chrome, Edge, or Firefox will significantly reduce the amount of data your browser sends to Google, Microsoft, and the sites you visit.

Below are five adjustments that have the biggest impact on privacy, with step-by-step instructions for each browser. No extensions required—though we’ll mention one at the end for those who want extra protection.

What Happened?

Browsers have quietly collected user data for years, but a few recent developments have brought the issue to a head. Google’s rollout of Manifest V3 has limited the effectiveness of ad-blockers like uBlock Origin in Chrome, making built-in privacy settings more important than ever. Meanwhile, Microsoft’s Edge has been adding features that sync browsing data across devices by default, often without making the privacy trade-offs obvious. Even Firefox, generally considered the privacy-friendly option, comes with settings that share telemetry and allow fingerprinting unless you turn them off.

Why It Matters

Tracking isn’t just annoying—it can follow you across the web, influence what you see, and in some cases expose sensitive information. Ad personalization, for example, builds a profile of your interests based on your browsing history. Third-party cookies allow companies you’ve never heard of to link your activity on different sites. And features like “background sync” keep sending data to the browser maker even after you close the window. Adjusting these settings won’t make you completely anonymous, but it will close off some of the most common data collection channels.

What Readers Can Do

Here are the five settings to change, with the menu paths for Chrome, Edge, and Firefox.

1. Turn off ad personalization and interest-based tracking

Each browser has a setting that lets you opt out of receiving targeted ads based on your browsing behavior. In Chrome, go to Settings > Privacy and security > Ad privacy. Turn off “Ad topics,” “Site-suggested ads,” and “Ad measurement.” In Edge, go to Settings > Privacy, search, and services > Personalization & advertising and turn off “Allow Microsoft to use your browsing activity for personalized ads.” In Firefox, go to Settings > Privacy & Security > Firefox Data Collection and Use and uncheck “Allow Firefox to install and run studies.” (Firefox’s stronger tracking protection already handles much of this, but this extra check prevents interest-based data from being sent to Mozilla.)

A note: ad personalization may still occur on the websites themselves, but this step stops the browser from sharing your data with Google, Microsoft, or Firefox’s ad systems.

2. Disable “Allow sites to check if you have payment methods saved”

This neat-sounding feature lets websites automatically detect whether you have stored credit cards or payment info in your browser. In practice, it gives every site you visit a way to probe your payment data—even if you never intend to buy anything. In Chrome, go to Settings > Privacy and security > Site settings and scroll to “Payment handlers.” Toggle “Allow sites to check if you have payment methods saved” to off. In Edge, it’s under Settings > Site permissions > Payment handlers. In Firefox, this feature is not enabled by default, but you can verify there’s no toggle under Settings > Privacy & Security > Permissions > Extra permissions.

3. Block third-party cookies (or tighten tracking protection)

Third-party cookies are the main way advertisers follow you across sites. Chrome still allows them by default, though Google plans to phase them out eventually. In Chrome, go to Settings > Privacy and security > Third-party cookies and select “Block third-party cookies.” (A quick note: some older sites may not function correctly, but the vast majority will work fine.) In Edge, go to Settings > Privacy, search, and services > Tracking prevention and set it to “Strict.” In Firefox, go to Settings > Privacy & Security > Enhanced Tracking Protection and select “Strict.” Firefox’s strict mode blocks not only third-party cookies but also social-media trackers and fingerprinting scripts.

4. Enable “Do Not Track” and “Global Privacy Control”

Do Not Track (DNT) is a request you can send to websites asking not to be tracked. It’s not legally binding and many sites ignore it, but it’s still worth turning on—it sets a clear preference that privacy laws like the CCPA may require some sites to honor. In Chrome, go to Settings > Privacy and security > Third-party cookies and toggle “Send a ‘Do Not Track’ request with your browsing traffic.” In Edge, it’s under Settings > Privacy, search, and services; scroll to “Tracking prevention” and find “Send Do Not Track requests.” In Firefox, it’s under Settings > Privacy & Security > Enhanced Tracking Protection; check “Send websites a ‘Do Not Track’ signal that you don’t want to be tracked.”

Additionally, Firefox includes a “Global Privacy Control” (GPC) setting that legally opts you out of the sale of your data in jurisdictions where that right exists. In Firefox, go to Settings > Privacy & Security and check “Tell websites not to sell or share my data” under Global Privacy Control. Chrome and Edge do not yet natively support GPC, but you can use an extension like “Privacy Badger” to send the signal.

5. Disable background sync and preloading

Background sync lets sites keep your data up to date even after you close the browser. It also sends regular pings to the browser vendor’s servers. Preloading allows Chrome and Edge to prefetch pages and even entire websites based on your browsing patterns, sending data to Google or Microsoft. In Chrome, go to Settings > Performance and turn off “Preload pages for faster browsing and searching.” Under Privacy and security > Site settings > Background sync, turn off sites from finishing sending data after you close the browser. In Edge, go to Settings > System and performance > Preload pages and turn off “Preload pages for faster browsing and searching.” Under Site permissions > Background sync, disable it. In Firefox, preloading is not a default concern—just make sure under Settings > Privacy & Security > Permissions > Extra permissions that “Use background services” is unchecked.

Beyond Settings: Consider a Lightweight Extension

Even with these changes, browser fingerprinting and some forms of tracking remain possible. If you want an extra layer without installing a heavy extension, consider Privacy Badger (from the EFF) or uBlock Origin (if you are on Firefox). On Chrome, uBlock Origin’s capabilities are reduced under Manifest V3, but the Lite version still blocks many trackers. Alternatively, using Firefox or a privacy-focused fork like Brave is a more permanent solution.
