Obviously, it's an old issue, but it even got worse. Mozilla removed the management of individual cookies, which makes it a nightmare to develop sites for me. Yet there was this "chrome://browser/content/preferences/cookies.xul" way to access all them cookies in firefox the old, good way. Well, actually this feature is also long gone from the main Firefox release, but it was still available in ESR version. Now, with the latest ESR version, it's gone too. It's impossible for me to understand why that happened, and frankly, i don't really care. There are no possible arguments which would make any sense. So, my question is whether it's coming back or not.
