This adds to the release note in FF131. The point here is that FF has a default of
Same-Site=Noneso ifSame-Siteis not set the restriction previously added to the release not applies. This is IMO significant because it will stop cookies that haven't specified their samesite cookie behaviour explicitly from working (unless they addSecure).Note comes from https://bugzilla.mozilla.org/show_bug.cgi?id=1909673#c8
