First, the flippant comment:
I find it astonishing that in this day and age when apparently they can track everything I do, want, and own online without my permission, my ATM still asks me WHAT LANGUAGE I want to use? Seriously? After I've answered that once, it's done. I'm not changing my native language guys. Offering it subsequently is doing a favor only for the foreign-language dude that steals my card.
Second, the serious one:
a) the site itself is fairly vague and misleading:
"Yes! (You can be tracked!)
36.34 % of observed browsers are Chrome, as yours.
27.11 % of observed browsers are Chrome 39.0, as yours.
55.61 % of observed browsers run Windows, as yours.
39.77 % of observed browsers run Windows 7, as yours.
59.03 % of observed browsers have set "en"as their primary language, as yours.
5.51 % of observed browsers have UTC-6 as their timezone, as yours.
You have the only browser out of 24041 with this fingerprint."
I call bullshit on that. You're telling me I'm the only english-language individual running chrome on windows 7 in the UTC-6 timezone? Absolute nonsense.
b) when you pull the 'more details" then it starts to get more plausible, where the specific list of addons I use is rather unique, but they go down to asserting that my browser is 'identifiable' due to WebGL output - really, are vendors doing this to fingerprint my browser (as is implied) or is this more of a forensic "if I was stupid enough to send a ransom note from my browser, the FBI could eventually confirm that it came from my machine if they had physical possession of it and some weeks"?
That's two different contexts of "unique", surely?
