The other side is not stupid, there are far better ways to track users than cookies, and blocking them takes a lot of effort.

What better ways than cookies is there to track users ? AFAIK, it's the most unique fingerprint you can get of a user. Everything else is probably going to be a lot less precise.

I think browser fingerprints are quite a reliable way of tracking.

I have a few questions. 1) “Facebook’s intrusion could have easily been blocked, but plaintiffs chose not to do so,” This seems like a dangerous precedent. So if we can block surveillance attempts and we don't try, then it's our fault? > “The fact that a user’s web browser automatically sends the same information to both parties does not establish that one party intercepted the user’s communication with the other,” T…

You're not very good at questions.

> This makes no sense. Nothing happens "automatically", someone wrote the code for that to happen, in this case, Facebook.

The website you are visiting has to deploy Facebook's code though. So the website owner has to allow it (assuming the know the implications of what they are doing).

Sure, 'quite reliable' beats 'unique' every time!

Firefox has a pretty neat feature I discovered recently:

https://wiki.mozilla.org/Security/Contextual_Identity_Projec...

It lets you run multiple sessions in one window, where each tab belongs to a specific session with separated cookies and such.

I've got a bunch of tabs where I'm logged in to Facebook, another set where I'm logged in to Google and the rest of them where I'm not logged in to either. Of course they can still use IP matching to track me, but at least it's something...

Your ISP adding a header containing your subscriber ID to every request.

I use the Tor browser for just Facebook. Stymies IP tracking, and I expect it to do more of the right things to deal with fingerprinting too.

Plus it's super slow, encouraging me to not spend too much time on Facebook...

That's not all. In NY state, they ruled that can artist can take pictures of you in your home through your windows: https://fstoppers.com/photojournalistic/supreme-court-rules-...

And why not? It would forbid a lot of outdoor photography if I couldn't accidentally catch a photo of someone in their house. Google Street view would be gone.

Proper English should have been: "Facebook may track your browsing even after...". The judge can rule about lawfulness, otherwise it looks like they are a investigative reporter that just found out about the technical capability to track users in such a way.

Was confused about the headline as well, made it seem like this was uncovered by the judge during the course of some trial.
