I understand: Javascript is not safe. I know that. But most of the internet, except for onions, use javascript and it’s nearly impossible to use most of the Internet in web browsers without it. The problem is that if Fingerprint.com can reliable detect differences between users when javascript is on for Mullvad Browser and Tor Browser in certain operating systems, users should be aware. Most people would think Mullvad Browser in “safer” mode would not create a persistent per-computer hash of the browser that can be tracked across sessions.

Other users on privacyguides forums have commented on the exact same problem where threads are just completely deleted, even with valid questions.

Then this may be happening only with certain distributions or operating systems. It is definitely happening for me, I checked it over and over. “You have visited once.” I close Tor Browser, restart, come back to fingerprint.com. “You have visited twice.” I also did try this with safer. I did multiple tests. This impacts at least some operating systems or distributions. It may not impact Qubes. I didn’t test that, but I am sure it impacts at least some users.

All users don’t have the same fingerprint. Fingerprint.com is testing other things that Tor isn’t covering. So if they are testing canvas and other stuff that Tor protects, and 2 things that aren’t protected that give unique identifiers, they still create a unique hash. I did not test this using Tails or Qubes and it may not affect all operating systems.

They have different unique hashes per computer, so Tor Browser user on “Computer 1” has a unique hash and Tor Browser user on Computer 2 has a unique hash. I have read Mullvad’s documentation on their browser. Please re-read the original post.

They have different fingerprints PER COMPUTER without any plugins other than default of No Script. I tested this, it is not the same hash for every computer. It varies per computer and was persistent across sessions.
