  We conclude the multiple fibration problem for closed orientable Seifert
three-orbifolds, namely the determination of all the inequivalent fibrations
that such an orbifold may admit. We treat here geometric orbifolds with
geometries $\mathbb R^3$ and $\mathbb S^2\times\mathbb R$ and bad orbifolds
(hence non-geometric), since the only other geometry for which the multiple
fibration phenomenon occurs, namely $\mathbb S^3$, has been treated before by
the second and third author. For the geometry $\mathbb R^3$ we recover, by
direct and geometric arguments, the computer-assisted results obtained by
Conway, Delgado-Friedrichs, Huson and Thurston.
