Results from the ALICE experiment on the production of muons from heavy-flavour decays, at forward rapidity, in Pb-Pb collisions at sqrt(s-{NN}) = 2.76 TeV are reported. A particular emphasis is placed on the measurement of the nuclear modification factor as a function of transverse momentum and centrality, and on the comparison to model predictions. First results on the inclusive muon elliptic flow are presented.
