Tried several browser engines and with my desktop pc (i7 3770-ssd-16 gigz ram-970 gtx) and with my laptop (i7 6700hq-ssd-16 gigz ram-igp/960m gtx)

aaand the low memory problem still persist

what am (we are) i missing? some security update/flash update missing or your engine needs a (lot of) bugfix ??? i don't know
