Comment:

 Seems this is actually a duplicate of #18500. I guess we dupe the older
 ticket to this one, though, as we have more info here.

 Useful info in the #18500 description is:
 {{{
 ​http://jcarlosnorte.com/security/2016/03/06/advanced-tor-browser-
 fingerprinting.html claims that getClientRects() provides a lot of
 differences between two computers. This is "[d]epending on the resolution,
 font configuration and lots of other factors".
