Every time I open Firefox, Kee disables the built-in password manager. I use that password manager, so please don’t disable it without asking.
This is important behaviour (as per earlier versions of KeeFox in order to prevent confusion). There’s already a discussion about this where a couple of other people used to override the behaviour in the earlier version of Firefox where that was possible. Feel free to contribute to that discussion too: https://github.com/kee-org/browser-addon/issues/55
