I think this has been discussed here before, but I don't recall a firm conclusion: has anyone established whether a nontrivial number of users are non-fingerprintable as things stand? If the vast majority of users can be fingerprinted right now, and there are no realistic plans to change that, it doesn't seem like we should care about increasing fingerprinting ability. I haven't investigated, but I'd be surprised if there are a lot of users who can't be fingerprinted yet, given the huge and rapidly-expanding number of features in the web platform. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
