They can even detect some extensions that are supposed to enhance privacy.

I ran their PoC on my Waterfox and compared to the same Waterfox build in a clean profile. I tested both Waterfox 68 (my current daily browser) and the last Waterfox 56 profile I have on hand. Interestingly, the PoC detected NoScript Classic, and (I guess not really surprisingly) it detected some of my about:config customisations. More interestingly, NoScript 10 in my configuration borked the PoC, where Classic didn't.
