The reality is that people want stats on their advertising and that’s fair, as much as we (rightfully) hate ads. Completely and truly anonymizing the data seems like an acceptable compromise in this world. Mozilla is one of the few entities left that hasn’t absolutely folded to capitalism, and I’ll take what I can get.
I think this might be anonymized enough where they can’t do the same old fingerprinting. But idk the full details. For anything else in terms of tracking, that’s where I recommend finding other tools and adding layers to anonymize and block further.
