Mozilla is not holding your back against browser, device or user fingerprinting. There are many attacks to fingerprint a browser/device/user, and Firefox doesn't protect you against them but instead it gives lots of data right away. It's disheartening to see so little care for defending the user.
There's anti-fingerpinting code in development which should ship in a few weeks in FF59. It's part of a broader initiative to port Tor Browser security features to mainline FF.
