How about using the Search bar at the top of the "Manage Cookies and Site Data" window?

You can click any of the column headers in Manage Data to sort by this column, so click the Site header. Note that the cookies are sorted by top level domain, so do not get confused by seeing various prefixes like www.

cor-el's answer helps. Sort of. One can get a little dizzy trying to visually tease out the repetitive prefixes in the list. Competent designers work hard to make their creations simple -- even (gasp) intuitive -- for the rest of us, the hoi polloi. As with many things, changes are not always improvements. As far as I can tell FF's cookie management worked just fine before but now it's as clumsy as a pencil sharpener is to a southpaw. This change to FF's cookie management is a provocative example of the sort that stirs up notions (surely unfounded) of elitism at worst or detachment at best in software engineers vis-a-vis the folks who use their creations. Is it to much to hope that the old format will return, or at least the prefixes will be grayed out in a future release? There are left handed pencil sharpeners.

Hi unclesuds, there are new cookie management extensions being posted on the Add-ons site regularly, so if you can't adjust to the new list, check there for possibly more convenient tools.
