according to browserstack, the current release 41 of Firefox on
Windows 10 seems still to use the GDI framework, which implies font
rasterizer version 37, compatible widths ClearType, no supixel
positioning, and no vertical smoothing (i.e., B/W rasterization along
the vertical axis) – this is exactly the same rendering mode as used
on Win XP.

Is this really true?  For me, it's hard to believe...

Just tried that in a VM, and yes, your test page reports version 37, compatible ClearType, no symmetrical smoothing.

By the way, is there a way to enable any of that in freetype? I know I can set engine version to 38, does it mean a set of parameters will be applied and there's no way to switch dynamically from one to another? E.g. enable symmetrical smoothing per render call, not per library.
