There is a per user preference for "Extended command output". When I set that, it only stays set for the duration of the session. If the session times out, or the user logs out and then back in, the preference is reset. I have tested this under Firefox 20-22, IE 9-10, and Chrome 27 - all behave the same and lose the preference setting after the end of the session.
Is there a method to make the preferences persist across sessions? I find the extended command output very useful.
