Hide a signal
inside the noise.

FckTracking floods your browser with random background visits — scrolling, searching, clicking — so the profile a tracker builds is buried in traffic that isn't yours.

Not a video — this window reacts to your keyboard.

Ads. Accounts. Telemetry. Servers.
Just noise, made locally.

FckTracking doesn't block trackers — it feeds them. While it runs, it opens random tabs, reads them like a human would and closes them again. Everything happens in your browser; nothing is ever sent anywhere.

Tuned for plausible chaos.

Manifest V3
01

Random background browsing

Opens tabs to random sites, scrolls them, optionally clicks safe links and accepts cookie banners, then closes them after a randomised dwell time. Link-clicking avoids logout, checkout, account and payment URLs by design.

02

Weekly schedule

A clickable hour grid — like a smart thermostat. Run the noise only when it makes your day look normal.

03

Adaptive mode

Looks at your last 7 days of activity and automatically fills the quiet hours, so the noise lands where you usually aren't.

04

Ten categories

Search, Social, News, Shopping, Entertainment, Tech, Travel, Finance, Knowledge, Sports — toggle what fits your cover story.

05

Your URLs & blacklist

Add your own sites (one per line, import/export as JSON) and blacklist domains that should never be touched.

06

Request spoofing experimental

Optionally rotates the User-Agent and referer per session. When rotating, the sec-ch-ua client hints are stripped so no contradictory fingerprint is produced. navigator.userAgent stays untouched — the masking is deliberately not complete, and the page is honest about it.

07

Stops staying stopped

An alarm-based heartbeat revives the loop if Chrome kills the MV3 service worker, resumes a running session after a restart and cleans up orphaned tabs.

The loop.

What it does — and what it honestly doesn't.

Helps against behavioural and interest profiles built from the sites you visit and the terms you search — it weakens history-based tracking.

Does not help against cookie- or account-based tracking: the noise runs over your real IP, your real cookies and possibly a logged-in account, so it can be linked to you. It also does nothing against browser fingerprinting. For maximum effect, run it in a separate browser profile without logins.
