About Tracker Blocker
Tracker Blocker is a lightweight extension that does a few things well, nothing more:
1. Blocks requests to known advertising and analytics tracking pixels, using both built-in rules and the community-maintained EasyPrivacy filter list.
2. Automatically strips tracking parameters from URLs as you browse or click links: fbclid, gclid, gclsrc, dclid, wbraid, gbraid, msclkid, the utm_source/utm_medium/utm_campaign/utm_term/utm_content set, yclid, igshid, mc_eid, twclid, ttclid.
3. Detects trackers disguised as subdomains of the site you're visiting (CNAME cloaking), a technique third-party trackers use to slip past ordinary domain-based blocking.
4. Disrupts common fingerprinting signals (canvas, WebGL, AudioContext, CPU core count, available memory, Battery API) without breaking how pages look.
5. Keeps a local activity log for awareness: which sites tried to load which trackers, and which tracking domains set cookies, with a dedicated stats, filtering, and export page.
No data collection, no account. The only outbound communication is an anonymous DNS query to Cloudflare, needed for CNAME cloaking detection. The activity log stays 100% local.
