This website isn’t very useful because every browser is unique, save Tor.

I use it as a benchmark for how well my blockers etc. are working. Yes you are unique initially but you can then tweak everything until you start becoming less unique.

For things that should always be unique (like a canvas fingerprint), just make sure to randomise it each time.

Basically, you want to appear as mundane as possible (user agent, screen resolution, fonts, platform etc.) and be able to change on demand as much of the remaining entropy (as is feasible) that would normally be expected to be unique.

I wish this was helpful, but amiunique.org calls out the values for canvas, fonts, etc. as unique when running the blockers. Maybe this is because it's randomizing every time, but it makes the amiunique test pretty flawed...

amiunique.org is just a database of fingerprints (size of which is governed by however much traffic they get).

If you're showing up as unique it's either because:

1. your blockers are randomising each time

2. your blockers aren't blocking everything and what's left is still enough to uniquely fingerprint you against the database of fingerprints they have.

If it's 1 above, that's fine. If it's 2, you may need more (or better) blockers.

Also, it obviously helps from the get go if you're on a bog standard platform like Windows and using FF.
