Very cool! Especially if you want to explore a special page. One star less for the bad UI ;)

Use expressions like *ali*.* to get rid of all ali[express] cookies for example, as I did to fix a stupid website language bug

No instructions on how to use it. Very confusing.

Only one problem of this add-on is difficult to notice cookie manager page can scroll right. So, at first, I cannot find where edit button is.

Fantastic. Does what it says on the tin in a no-nonsense, usable way. Just what I needed.
