This can't be right. According to that site, my HTTP_ACCEPT header of "text/html, <i>/</i> UTF-8,* gzip,deflate en-au,en-us;q=0.7,en;q=0.3" is unique. Uh .. is it? Looks fairly standard to me?<p>System fonts are a very telling fingerprint, though. I tried the test on two browsers; the first time it said I was one in ~60k, the second time was one in ~30k. So it is working.
