No, they can’t access those cookies. What they can measure is that you’re clicking Lemmy links on Reddit, or that you’re navigating to Lemmy from Reddit using the Referer header: https://en.m.wikipedia.org/wiki/HTTP_referer
cookies. (unless you’re using Firefox) cookies from one website work on all website. this also means that Facebook, once you’ve accepted their cookies, sees what you’re doing on every website
Tell me you don’t know how cookies and user tracking work without telling me.
This is blatantly false. Facebook-cookies can only be used to track you on websites that sent requests to Facebook (for example by displaying a share-code). Without making some kind of request to Facebook servers, cookies are simply little text snippets doing nothing.
The problem is that so many websites have in one way or another introduced code-snippets from Facebook or Google or Instagram or Youtube. Those snippets then fire requests to their servers and boom, that’s when your cookies can be used to identify you.
But Lemmy does not include any code snippets from Meta or Alphabet, so the only way to track you going here is through referrer when clicking on links.
@teije9@lemmy.blahaj.zone has enough knowledge to dunning-kruger themselves into the valley of informed-misinformed but not enough knowledge to truly understand how shit works and get out of it again.
no, but if youve accepted cookies on reddit and (unless you’re using Firefox) those cookies still exist and work even if you’re visiting other websites. meaning that Reddit can see that you’re visiting lemmy
That’s… not how cookies work. They’re only accessible by the website that set them, and unless Lemmy starts embedding reddit content into its pages, there’s zero way for Reddit to know that you’re here.
Wait. Why would reddit have access to the Lemmy cookie?
It makes sense that Facebook knows what sites you’re visiting because of the “share on Facebook” buttons that read your Facebook cookie, and of course Google tracks you via its ads and analytics network, but sites don’t have unlimited access to all of your cookies. That would be insane.
Reddit doesn’t have access to ‘the Lemmy cookie’ but the Reddit cookies are still active when you’re visiting other websites. Firefox blocks this though
What do you mean “active?” It’s just a file on your computer. Reddit has to actively look for the cookie, which they can do if they have a “share on Reddit” button on the websites you visit. But Reddit doesn’t know all the websites you went to that don’t have this button just because you have a cookie.
How do they know that you’re going between them? Are you clicking on lemmy links in reddit?

Does lemmy have reddit cookies? That doesn’t sound right…
No, they don’t know what they are talking about.

The fact that Facebook can do that because they have their little buttons that are embedded in so many webpages is redicilous.
Firefox multi-tab containers combat this, right?
