Recently the measurement of (at least) two very massive neutron stars plus the theoretical predictions related to the effects of magnetic fields on the QCD phase diagram shed a new light on the possibility that magnetars can be constituted of deconfined quark matter only. In this work we revisit the conditions for stable quark matter by investigating stability windows for different models at zero and finite temperature and checking the resulting stellar macroscopic properties. Once magnetic fields are considered, investigating anisotropy in the pressure becomes mandatory and this topic is also considered.
