FYI I wouldn’t say that the Mullvad browser is any better at anti-fingerprinting than Librewolf. I always point people to http://fingerprint.com/ so they can see how difficult it is to beat even JS based tracking and this doesn’t even get into the server-side methods (i.e. just fetching a stylesheet) of tracking users.

That’s not to say you shouldn’t use a browser that blocks ads etc but I don’t think people should immediately think that they’re not fingerprintable because they’re running these. There definitely needs to be more discussion on the reality of how much these browsers can “protect” you.
