I don’t think it’s anyone’s fault for being confused or misinterpreting what’s in the article, because even Mozilla calls it blocking:
And starting in 2024, all our users can look forward to Firefox blocking even more third party cookies.
The linked page is even more confusing, because it provides a link back to this page for clarification about which third party cookies are being blocked.
Compare to what Mozilla shows their users in a pop-up tab after the update:
https://www.mozilla.org/en-US/firefox/130.0/whatsnew/
Isn’t it strange that it doesn’t mention anything from the release notes on this page?
The only thing it does mention, Close Duplicate Tabs, isn’t mentioned on the release notes.
