“Meta devised an ingenious system (“localhost tracking”) that bypassed Android’s sandbox protections to identify you while browsing on your mobile phone — even if you used a VPN, the browser’s incognito mode, and refused or deleted cookies in every session.”
im wondering, does using uBlock help in any way? can they block metas pixel and thereby protect you?
Yes. Because it blocks the meta pixel script from loading to begin with.
I would say it prevents the downloading and execution of such a script. DNS adblock would probably help too.
there is a blocklist with a name like block outsider intrusion to lan, but it’s off by default
