I think browser fingerprints are quite a reliable way of tracking. https://amiunique.org/fp

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

Unique becomes unreliable the moment users delete their cookies.

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 c…

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...

Why not just quit Facebook?

Do you use facebookcorewwwi.onion? Before I deleted my Facebook account last year that was the only way I connected to it.

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…

The most interesting thing to me about "Facebook's intrusion could have easily been blocked, but plaintiffs chose not to do so," is that it implies that users have a right to block tracking code.

If that isn't already enshrined in case law, hopefully it signals that we will not get laws passed requiring users to allow tracking, and the courts will hopefully invalidate terms and conditions requiring tracking.

Having lived through the rise of DMCA, I live in fear of an emboldened industry getting laws passed that make the use and distribution of blocking software illegal.

For me, the reason is "Because there are people on Facebook that I want to communicate with".

Wouldn't opening several "Private Windows" achieve the same situation? What are the differences?

I don't think so: I'm currently logged in on HN. When I open a new private window, I'm logged in as well.

This is really annoying when you always use your web browser in private mode, but don't close it regularly. It means that e.g. youtube already builds a profile about me from my previous searches even though I'm not logged in. If I were that concerned I would close Firefox, but the usability issue is just too big for me. Having the best of both worls would be awesome.

Several private windows share the cookies. Try logging into a website in a private window and open that website in another private window and you will be logged in.
