Hello, I'm the creator of a new fingerprinting website, https://browserprint.info
Think Panopticlick but with a lot more tests.
Many of the tests are even designed specifically to catch the Tor browser bundle out, for instance the Math/Tan function returns a different value based on what your underlying operating system is, so it's easy to detect when a browser is lying in their user-agent string.
I would greatly appreciate if you visit the site and fingerprint yourselves since it will help me refine the techniques and improve the site.
I'm adding more tests every week and if you have any ideas or suggestions I'd love to hear them.
