Does a great job - as multiple of his addons!

Great

Starts to break some sites after the last Firefox update

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 :)

Singlehandedly flipped my result on https://coveryourtracks.eff.org/

This needs to be more widely known!

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.

This is great, but it breaks jellyfin's media player's menus

It does a good job with the spoofing. Thanks to the developer...

Nice, i suggest an option wich shows the default out-of-the-box windows fonts, i think this could be more low profile

The motivation for the author of the webextension is good, but... it did not protect the browser user from the fact that ANY tracking company can easily deteсt that you are using the extension to bypass the reading of your real data. So you are already trying to hide from them and this is a huge fingerprint. Webextension code needs to be rewritten significantly in order to protect it from detection. Good luck to the author, but in this form, the extension only pays attention to tracking companies.
