On the internet, it’s easy to feel anonymous. If you don’t log in, no one can see who you are; you can even switch to incognito mode. The more savvy user would say that’s not really enough. To be anonymous, you need to clear your cookies and use a privacy-oriented browser.
But new research shows even that doesn’t work anymore. Websites are still tracking you — silently, persistently, and without your consent — by reading your browser’s unique “fingerprint.”
Mullvad browser fights fingerprinting. You can check how exposed you are here (no idea how good this site is https://coveryourtracks.eff.org/)
No anti-fingerprinting method currently in use can evade creepjs to my knowledge. And that EFF site has its own issues… it only tests uniqueness across other visitors the site has seen before, and not all possible combinations of data points.
Any Firefox-based browser can be made to do this (I use Zen). This might not be totally bulletproof in this day and age.
