great news!
Since there's no Cookie6 forum (yet), I'll just followup here.
Will Cookie6 have "profiles"? On Chrome, profiles are a unique set of cookies, as well as other stuffs (extensions, eg).
On Safari, I'd love to have profiles-lite, which would just be cookie set switching. This wouldn't work around (eg) browser fingerprinting, ie recaptcha and anyone evil can still tell you really are still the same person using the same browser, but it would provide the very valuable ability to manage multiple logins to the same site simply by switching all the cookies.
Not too different from Firefox containers.
Or does Cookie5 already have this feature and it's just not highlighted.
You could call them personas.
