Everytime I go to the EFF fingerprint page it tells me I have a unique fingerprint. If I revisit it an hour later it tells me I have a unique fingerprint.

It would be great if it would give me a hash of that fingerprint so I could compare it in a few months time.

I'm guessing that my "fingerprint" changes every time I load the page, which makes it somewhat harder to use for fingerprinting me.
