MOZ_ENABLE_WAYLAND=1
Thank you - I was already aware of this, actually, but I choose to leave it disabled because when this is set, touchscreen drag-scrolling of webpages breaks and it selects text as though it were a mouse click-drag instead. As it turns out, I barely use Maliit anyway because of its other deficiencies, but I definitely touch-scroll my browser a lot, even in laptop mode. A generally disappointing dilemma!
