Chrome is linux origin, aka google, Personally, but for the observations, my chrome gave 4 on winows, could not care less what some want to spend their time on in the true, not true department. It's by and large irrelevant, but for the excess time fillers.

For what it's worth, if you zoom in and out in firefox (hold control button and move scroll wheel), it seems to alternate between 4 across and 5 across.
