Hello, smart people. Filling out an online form to volunteer for something, Firefox’s Facebook-fence icon appeared on the email field. Confused, I clicked on its question mark. On the next page, Mozilla wanted to sell me Firefox relay for $7/mo. (That’s their VPN + email masking + phone masking.) I used my yandex.ru email address instead for $0. Here’s the question: is Facebook really able to track me because I’ve signed up to volunteer for Cornel West (setting aside the FB-Russia blockage issue)? Thanks.
I just looked up fingerprinting. Yuck. Is there anything FOSS that defeats it?
Firefox has blocked browser fingerprinting since v72 (we’re at v117 now) - nearly 4 years now.
Firefox does a decent job blocking it: https://www.mozilla.org/en-US/firefox/features/block-fingerprinting/
See https://amiunique.org/fingerprint
If Firefox blocks it, why am I unique according to that site?
Not usang their services. I’m doubtful any technical measures achieve appreciable results here.
