2024-01-01 Quaesitrix Tested on https://browserleaks.com/ and https://webbrowsertools.com/font-fingerprint/ Seems to work fine, I get a different fingerprint ID each time I load a page :)
2023-10-17 jkappes Singlehandedly flipped my result on https://coveryourtracks.eff.org/ (Used in LibreWolf) This needs to be more widely known!

2023-04-01 Snadberry Completely unobtrusive and does what it says. And ignore the reviews that say this add-on makes your browser more unique, because they don't understand how it works. It's creates a *different fingerprint every time*, which means it no longer consistently identifies your particular browser. Of course random values should be unique.
