Hi, I have a lot (+1600) password stored in my profile and i would like to clean its and delete olds ones. So i look for an utility or an extension to mark only those i want to delete (or keep).

Can i make an export to csv file, open it with excel (or something else) delete these unused, save the new csv, delete all password in firefox, and import the new csv ? Have i to make an new synchronisation in all my pc,tabs,phones after deconnexion on its? Many thanks for help JP from France
