@axels my favorite tool doesn't exist.

In today's current online environment, if you don't want your online behavior following you around, you need to shake your device fingerprint. There's no way around that, really. For some people, this looks like a multi-login #browser for others, it's just using different browsers for different tasks. The #tech simply does not exist to allow the average consumer to stop trackers from following them everywhere they go on the #internet.

When an adversary can link your behavior across sites and sessions, that gives them the ability to build a comprehensive profile of who you are. Your hobbies, interests, schedule, habits, worries, and beliefs all crammed into one profile.

I've found that I can successfully make my device appear as another device by modifying HTTPS headers, #JavaScript, TLS fingerprint, and network telemetry values (like TTL, MSS, window size, etc.). This #privacy approach allows me to scrub my browsers native fingerprint and replace it with a new one.

The key is coherency, though, tools like fingerprintJS can detect mismatches between headers and JS advertised properties and flag the user as a bot. Though, browsers like #firefox, #brave, and #duckduckgo do a good job of mitigating many of these fingerprinting techniques.

I've developed some #opensource tooling to give users free control over their data.
