 Yan has a brilliant slide deck on browser fingerprinting, here:
 https://zyan.scripts.mit.edu/presentations/toorcon2015.pdf

 We need to figure out which of these vulnerabilities Tor Browser has, and
 fix them. Do we need to isolate HSTS and HPKP caches to URL bar domain?
 Apparently #1517 (reduce JS time precision) helps protect Tor Browser from
 Yan's implementations, but there may be ways around that limitation.

 There is also a demo here: https://zyan.scripts.mit.edu/sniffly/
