How to Block All Tracking on Chrome Without Breaking Websites

You can't block every kind of tracking, but you can stop most of it in Chrome with a few settings and one or two extensions. The trick is knowing what tends to break and how to fix it quickly.
Step 1: Chrome settings
- Block third-party cookies: Settings → Privacy and security → Third-party cookies → Block third-party cookies. This stops most cross-site tracking cookies.
- Secure DNS: under Settings → Privacy and security → Security, turn on "Use secure DNS", so your internet provider can't easily see every site you look up.
Step 2: a tracker blocker
A content blocker stops tracking scripts and pixels from loading at all. uBlock Origin Lite, Ghostery and Privacy Badger all work in current Chrome. Use one, not several: overlapping blockers are the most common cause of broken sites.
Some of these also send a Global Privacy Control signal, which tells sites not to sell or share your data. In California and several other US states, sites are required to honor it.
Step 3: cookie banners and leaks
- Cookie Auto-Reject clicks "reject" on cookie banners, so sites don't get consent to set advertising cookies.
- WebRTC Privacy Shield stops your real IP address leaking through WebRTC, which matters if you use a VPN.
What tends to break, and the fix
- "Sign in with" buttons and embedded logins. Allow third-party cookies for that site: click the icon left of the address and turn them on for the site, or add it under Third-party cookies → Allowed.
- Payment verification pop-ups. Turn the blocker off for the shop's site while you pay.
- Comment sections, embedded videos and chat widgets. Allow the site in your blocker's menu.
- A site that won't load at all. Pause the blocker for that site and reload. If that fixes it, keep the site allowed.
Allowing one site keeps the protection everywhere else.
What this won't stop
- Tracking by sites you sign in to, using your account.
- Server-side tracking, where a site shares your data from its own servers.
- Most fingerprinting, which uses your browser's characteristics. See fingerprinting explained.
To reduce what remains, use separate browser profiles, and consider Ghost Browser, which adds random background browsing to make ad profiles less accurate. For a full setup, see privacy extensions that work together.
