    I would be more okay with this if Firefox did more to block the tracking techniques that advertisers are currently using. They block third party cookies and compartmentalize social media cookies which is fine but they do almost nothing to stop the more insidious tracking techniques like device fingerprinting.

    Mozilla really wants to push me to Brave

      What more do you think should be done to stop fingerprinting, and does that involve sacrificing usability?

      (Also, “almost nothing” feels like a gross exaggeration? Just the Tor Uplift project brought in lots of measures, quite a few of which could even be enabled by default.)

        Brave randomizes the output of fingerprinting techniques like canvas rendering, system fonts, installed devices, etc in a way that makes you look like a real, consistent user providing real data that still allows the site to work, while still changing the output from one session to the next enough that sites can’t tell you’re the same person.

        Firefox claims to block all this but if you check their site they explain how it actually works:

        Firefox protects users against fingerprinting by blocking all third-party requests to companies that are known to participate in fingerprinting

        We’ve partnered with Disconnect to provide this protection. Disconnect maintains a list of companies that participate in cross-site tracking, as well a list as those that fingerprint users.

        This does nothing to actually disguise you. It’s the equivalent of putting a paper bag over your head when you think there’s a security camera. You stand out because of the bag and you don’t know where all the cameras are so you’re still being tracked when you don’t know it.

        I hate the idea of Brave because Chromium’s dominance will ruin the web but Firefox does not protect us.
