But I might think because Tor is so rare, so rare, that Google would know it's me. Almost like a proxy right, which Google can figure out?... if that made sense. (Google has good proxy detection)
bTW notice in Panopticlick that most of the identifying thing is the system fonts, am I wrong on that? So if you could just block visibility of those...
I'll guess that at its safest setting Tor blocks so much stuff that Google won't allow you to "play" under any circumstances.
I don't see how system fonts can identify you when every Mac running a particular version of OS X/macOS, perhaps even every Mac, has the same font set; user installed fonts, sure, but not fonts that the OS, itself, installs.
