Either that sight is a lie or I am SOL. I have tried alot to get uniqueness low but today I got near 6 million. I am using ublock origin, privacy badger, Disable Plugin & Mimetype Enumeration, better privacy, https everywhere and the following ff tweaks from ghacks
First test: Javascript disabled. If you assure your user-agent string is a common one, you'll be one in thousands if not better. Second test: Javascript enabled, but no Flash (if you have it). Javascript is a major risk because it is used to interact with DOM/etc and acquire more information. Panopticlick is really just a POC. The fingerprinting risk is much much worse than it suggests, especially if you run with Javascript enabled and make unique combinations of changes to your browser. Browser plugins is a doozy, but IIRC plugins.enumerable_names should help. One in low millions or better should be possible. Allowing Flash will expose System font info. You could try setting DisableDeviceFontEnumeration=1 in the mms.cfg file. You can play with some other settings via the file or control panel thingy.
