Status Bar and focus() to secondary child [popup] windows

[DU]

Despite setting
Tools/Preferences.../Advanced/Javascript/Enable Javascript/Allow Javascript to/
and then unchecking the Hide the status bar checkbox,
secondary child popup windows still can be built without a status bar as the author can add status=no in the window features list.

One thing that annoys me even more: if I check the
Raise or lower windows checkbox,
a secondary child window will still not gain back focus after a

if (WindowReference != null && !WindowReference.closed)
WindowReference.focus();

This work well in all other Gecko-based browsers
(NS 7, and at least 10 1.2beta nightlies).

best regards
