GridFox work on FF 19.0.2 windows 8 -64 bit last update. Best ll be have a way -----to change color of gutter or column----that gridfox stay visible when thepage is reload ( need to reactivate it when css change occur) ..........................................................................................................................................................................................take care of 1) zoom normal for browser , and 2) of column size gutter (1/2) added by some web grid tool in righ and left side (1kb CSS grid) . if you work on 960 px , site width in gridfox must be 940 px
