Comment (by tom):

 https://tor.triop.se/ identifies the version of Tor Browser used (and
 sometimes OS). It doesn't identify users uniquely. If anything, it
 confirms that we're doing a pretty good job that someone smart poked at
 this and this was the best they could do.

 brax.me/geo/ is a bit harder to read - the code isn't as clean/well
 documented. But I'm not given much confidence by it with comments like
 "it's impossible to detect incognito mode". It does some WebGL
 fingerprinting, and AudioContext, but aside from those I don't see
 anything particurally inventive or concerning.
