Cookie Manager was the only thing that made the newer (at that time) Firefox work for me, and now it's gone, too. When I'm browsing the web, I sometimes want to delete only cookies from specific visited sites. Now I can't even do that with Cookie Manager anymore. Remember when we could just do that within Firefox? And then they got rid of that. And now Cookie Manager is gone, too. So to delete specific cookies, I need to clear them all and then log in (once again!) to the pages I want to still be logged in to. Please bring back the option to delete only specific cookies!
