Description

Add a warning about third-party cookies blocking in Google Chrome.

Motivation

Google Chrome will gradually block third-party cookies for all users in the second half of 2024, so I've added a warning for SameSite=None.

There is much more about third-party cookie deprecation here: https://developer.mozilla.org/en-US/docs/Web/Privacy/Third-party_cookies and it would be good to cross-link. Also cc @chrisdavidmills who has been on a lot of this work.

@wbamberg I updated this with cross links to third party cookies and CHIPS. I'm OK to merge this, though I may do more work as part of FF128 support for CHIPS.
