Browsers are changing tracking again: what it means for your fingerprint
Chrome keeps postponing third-party cookie removal while Safari and Firefox already block them — and fingerprinting fills the gap. Here is what the shifting landscape means and how to test yourself.
What is changing
Third-party cookies are dying unevenly. Safari and Firefox block them by default today; Chrome has repeatedly delayed its own phase-out while pushing Privacy Sandbox APIs such as Topics as a replacement.
The result is a split web: the same site can track you one way in Chrome and a completely different way in Safari. Cookie-centric advice no longer covers every browser.
Why fingerprinting fills the gap
When cookies stop working reliably, trackers lean harder on stateless identification: canvas and audio rendering quirks, installed fonts, screen and locale signals — the exact signals this site measures.
Privacy Sandbox does not end fingerprinting either. It changes which APIs are available, so the defense stays the same: a common, hardened configuration that reveals as little as possible.
Test yourself in two minutes
Run the fingerprint analysis and the tracker detection on this site, note your results, then apply one hardening step — for example strict tracking protection plus a content blocker — and re-run.
Save privacy-score snapshots before and after so you can see which change actually moved the number instead of guessing.
