Fingerprinting, trackers, pixels

Browser

Your browser is the single most data-rich surface you carry. Fingerprinting identifies you even in Incognito; the Meta Pixel tracks ~22% of the public web via CAPI that blockers can't see. A thinner data footprint also means a less precise behavioral profile — the raw material platforms use to predict and amplify your emotional responses.

  • Install a content blocker (uBlock Origin or Brave)

    ManualHigh

    uBlock Origin on Firefox or native shields in Brave block the majority of trackers and the Meta Pixel by default. Safari and Chrome content blockers exist but are less capable. This is the single highest-leverage browser change.

  • Know what Incognito / Private mode does NOT do

    ManualMedium

    Incognito and Private Browsing clear cookies and history at session end. They do NOT change your browser fingerprint — canvas, WebGL, audio context, and font fingerprints stay identical. VPNs change your IP only, not your fingerprint. For real fingerprinting resistance use Tor Browser or Firefox with 'resistFingerprinting' enabled.

  • Block third-party cookies

    ManualMedium

    Safari and Firefox block third-party cookies by default. Chrome is rolling it out. Third-party cookies are how cross-site ad targeting worked for decades; blocking them is free and breaks very little.

  • Use encrypted DNS (DoH / DoT)

    ManualLow

    Your DNS resolver sees every domain you visit. ISPs have sold this data. Encrypted DNS (DNS-over-HTTPS or DNS-over-TLS) hides it from the network and lets you pick a privacy-respecting resolver (Cloudflare 1.1.1.1, Quad9, NextDNS).
