I have win 7 64 bit and on that a win 7 32 bit virtual under VMWARE. Panopticlick fingerprint is unique in approx 200,000 for both- very slight single figure difference between the two- even though the virtual does not have as many addons etc. And approx18 bits of identifying info Both are firefox set up more or less the same way. Or does it read the real system even when testing virtual browser? Is is unique in approx 200,000 bad or good? Is it better a higher number or lower? Has anyone used Panopticlick privacy badger? Is it safe?
