I mean “1 in 122.7 million browsers look like” mine meaning it got me down to one out of about 2% of all internet users globally. I’d say it’s still pretty difficult to target anything at that many people and have it be relevant. Just knowing my location and that it’s a weekend basically gets down to that many or maybe fewer people on it’s own since fewer than that live in my city permanently, and adding tourists/visitors and people who work on weekends, that might be about right for how many devices are online in my city right now. And that was browsing with my less locked down browser on my phone.
Actually, looking with ironfox, though, actually reduced that to about 112m. I think part of that is that ironfox apparently still seems to enable the “do not track flag” even though it was removed from Firefox because it actually made people more easy to track and no sites who track are ethical so they are not going to obey something like that. So now it’s rare and makes for a really good tracking point. Need to figure out how to remove it from ironfox I guess.
Your math is not mathing, 100/122,700,000=0.000000814995925% not 2%
Also this seems to be a vibe coded website and probably doesn’t use the most advanced fingerprinting techniques. Most likely your browser is actually unique if you go to https://amiunique.org/ you might get a more accurate answer.
I was doing a little more complex math than just the 1 in 122.7m. That seems to be unique browsers not unique human users. I added some calculations based on how many browsers are used by humans vs bots and various other nonhuman users. It’s extreme rough with a lot of guesstimation and rounding based on some googling. But that’s beside the point.
I was trying to figure out the difference between fingerprinting a Mozilla Firefox browser from the play store and the IronFox browser from Fdroid. I had expected it to be significantly reduced accuracy since it’s explicitly set up to be more resistant to fingerprinting than vanilla Firefox.
When I did some digging and looking at other sites. The biggest factor seems to be the combination of it reporting Firefox as the agent and having the DNT flag and the global privacy flag or whatever it is called. Since only Germany has been able to enforce those legally and only in a single case against LinkedIn, but no cases against the bigger tracking companies that aren’t user facing and thus wouldn’t even care about legal stuff since proving standing with that many layers would be difficult, Mozilla decides to remove those a couple of years ago as many people weren’t setting them and so it made people who were setting them more susceptible to fingerprinting since they were more unique. IronFox has argued that the settings should stay on because it’s legally enforceable in Germany and maybe some day will be I’m other places. But IMHO that doesn’t help people getting fingerprinted now or for the next many years. And now since IronFox is basically the only one doing it, the combination of Firefox agent and that header flag means it narrows you down to IronFox users almost exclusively other than maybe some people using really old versions of Firefox, but you could add some criteria that gibe you the version, too, and how many of those are there in the world. A very small percentage of all internet users. And combine that with UTC offset and if you live somewhere like UTC-1 I bet you’re the only user. LOL.
But even in other less tech savvy areas of the world it would be pretty small and a few more data points could easily get you a unique user. People in places like UTC+2 or mainland US, probably there are a lot more privacy thinking folks using IronFox or any other.
Anyway, I changed those settings manually in about:config based on feedback from the IronFox dev that it was set on purpose. But I haven’t had a chance to see how much less unique it made me yet.
