Doesn't the firefox resistfingerprinting setting fuzz most of these things? I see a lot of misconceptions about it on here when people use amiunique. It will say you are unique but if you look for a historical match there aren't any because you are unique, but also different each time you show up.
This gets lost a lot - just because you can prove uniqueness doesn't mean it's persistent or repeatable. Some of the "uniqueness" factors include things like number of audio devices or battery life.
