Enpass made a really fine mess of this, which other such password manager apps did not. The extention is not being updated in Mozilla's Add-on store, instead there is only this 'pre'-release and not apparent development, neither on the extention nor on the core. Wondering whether Enpass is in the process of quitting or selling or something, but not developing.
If this is supposed to be a 'pre'-release from end of September then why is there no release in the Add-on store 2.5 months later?
