You don't want a randomised fingerprint, as that is relatively unique among a sea of fingerprints [1]. What you want is a fingerprint that's as similar to everyone else (generic) as possible; that's what Firefox's resist fingerprinting setting aims to do, and what the Tor browser does.

[1] There are many values you can't change, so the randomisation of the ones you can change could end up making you more unique ... think of it like having your language set to french but are based in the USA — that language setting can't uniquely identify the French in france, but will stick out like a sore thumb if set in shitsville Idaho. It's likely the same if you use firefox but have your user agent set to chrome; that's more rare and unique than not changing the user agent at all.

No, that's absolutely incorrect. You want a new fake fingerprint every single time someone asks your browser for your information. You want it to lie about your plugins, user agent, your fonts and your screen size. Bonus if you use common values, but not necessary.

The randomized data they're providing isn't static and it isn't the same from session to session.

100% White noise is a far better obfuscation than a 40% non-unique tracking ID. Yes, your data is lumped in with 47 million other users, but used in conjunction with static pieces of your data you become uncomfortably identifiable.
