I'm running the latest developer build and it still has this. It only shows number of cookies by domain and allows deletion by domain, and you'd have to use dev tools if you wanted to look at or delete a single individual cookie.

Hmm, are you sure about that? IIRC, Firefox 90 had ability to remove cookies per exact subdomain in that view (i.e. account.google.com), since version 91 there's only an option to remove cookies for whole google.com domain...
