@Migueldeicaza@mastodon.social I know you knew the browser provided all of that before you opened the link. I did too. Were you still as freaked out as me, even though you knew it was gonna happen?

@Migueldeicaza@mastodon.social funny thing, if I use an anti-fingerprinting browser and a vpn and stuff like that, most things this page tells me are fake, but there is another website called something like amiunique.org, which tells me that the combination of all the fake things about me can still uniquely identify me on the internet... at least among its other visitors I guess

@Migueldeicaza@mastodon.social Vivaldi was found wanting. Firefox was quite a bit better. Firefox Focus was basically the same. Surprisingly Cromite was the best overall. All, for whatever reason, reported the exact gyroscope position. My question is why the fuck do browsers even report this data

@Migueldeicaza@mastodon.social > You have not enabled Do Not Track. This is the default. It means either that you chose not to, that you did not know it existed, or that you know it makes no difference. All three possibilities are informative. Statements dreamed up by the utterly deranged

@Migueldeicaza@mastodon.social it did not identify my browser correctly

@Migueldeicaza@mastodon.social Is there a way to prevent this?

@Migueldeicaza@mastodon.social it was off on my location by 600 miles

@Migueldeicaza@mastodon.social tried it with tor browser. It does not know about gyro or so..

@Migueldeicaza@mastodon.social ehh, a lot of scare tactic language, and not a lot of actual explanations of the potential danger. like, the "what renders your world" tells me nothing about how this information can actually be weaponized in any way. or how it can tell what fonts i have. So? it gives no explanation for why this is dangerous (if it even is) 🫤

@A_Minion@mastodon.social 2026-05-09 16:45
@Migueldeicaza@mastodon.social It's location was 5000miles off. It's time said afternoon when it's morning. Makes me think tor does a pretty good job.

@Migueldeicaza@mastodon.social this is cool but at this point I can practically smell LLM-coded websites. They all look the same. This one feels LLM-written as well.

@Migueldeicaza@mastodon.social lol it got half of the things incorrect, despite me not taking any particularly extreme measures to protect anything.

@opossum@therian.zone 2026-05-09 17:36
@Migueldeicaza@mastodon.social most of this didnt shock me much. except for yhe fucking gyroscope why the fuck are websites using this data??? spooked me so much i enabled the sensors off dev feature on android

@Migueldeicaza@mastodon.social happy to see almost all the data are completely wrong. Using Firefox with privacy plugins pays off.

@Migueldeicaza@mastodon.social Fun stuff, it says I am in Lepzig, but opened the page from another far away city. Says I have a very modern extremely high resolution screen, that is spoofed and changes quite often. Browser Firefox, well it is broadly based on it. Languages in the browser, it got those right. Fonts, told me I am unique, except it was spoofed too. For those using plain firefox or chrome, chromium the results will be way more interesting. For Tor it gets stuck enumerating the browser.

@Migueldeicaza@mastodon.social this is a cool page, but it’s also run by a grifty AI thing

@ruurd@mastodon.social 2026-05-09 20:40
@Migueldeicaza@mastodon.social @bartt@mas.to Yeah right. We already knew this for ages. And region lookup based on IP. We can do that at least for 40 years. So. What's so scary?

@Migueldeicaza@mastodon.social It will never know that I did not click the link.

@Migueldeicaza@mastodon.social Well done on the part of this old version of #Fedilab's built in browser for spoofing half the results to obscure my identity! I wish it blocked the power API though...

@Migueldeicaza@mastodon.social i like the idea location completely wrong What renders your world GPU: kept back Your browser masked your graphics processor Battery: kept back Your browser kept your battery level back. Firefox removed this API entirely in 2016 0° from horizontal Your device is nearly flat — you may be lying down. The gyroscope reported this without your permission (I guess the quib about permissions is not working that well here lol) So I guess I am not doing that bad

@Migueldeicaza@mastodon.social > Your device reported your timezone before the page finished loading. A website knowing your local time can infer when you sleep, when you work, and when you browse because you cannot sleep. Nothing about this was requested. The information arrived on its own. yeah I know it was sent that's why I sent it. It's useful to me as a user to have everyone else use my local time at on point this is just technology working as expected

@Migueldeicaza@mastodon.social it's always a bit chilling to be reminded how much data we're transmitting without even being asked or told. I also didn't realize that my browser was fingerprinting so I appreciate the heads-up.

@Migueldeicaza@mastodon.social it was almost entirely wrong for me 😂 but i'm a special snowflake.. but honestly most of that is the info a server needs to send you a reasonably complex page and make it work ok for you. webpages have been turing complete for a minute.

@Migueldeicaza@mastodon.social I suppose I am comforted by how many things it got wrong.
