Last I had checked, using the browser bundle in Tails with javascript disabled puts the fingerprint to about 1 in 22,000, but it's been a couple months since I last tested. Going to fire up my machine and see what it shows now, will report back with results shortly.

Update: Tor Browser in Tails 1.2 with javascript disabled returns a fingerprint that's shared by 1 in 2,615 with 11.35 bits of identifying information.

How do I have more identifying bits of information, but it's shared by more browsers?

>Currently, we estimate that your browser has a fingerprint that conveys 12.27 bits of identifying information.

I figured it would be more unique due to my running Tor Browser on a Mac - but I don't see how the math works out. Unless it actually has a count of machines with information identical to mine?

How else would it work (not assuming even distribution)? Im sure its a hash counter.

1/4955 means your fingerprint is shared by fewer browsers than the other commenter's 1/2915.

If your fingerprint is totally unique (like mine, with 22.16 bits of information) then it is shared by only 1 in 4,697,672 browsers in their dataset.

Is that not rather narrow? How is it not say 1 in 100k?
