The settings provided do indicate that Firefox has picked a different default subpixel layout than what the monitor has.
This can be because of a bug in autodetection but it can also happen when you orient your monitor vertically, which many people do with secondary monitors.
Assuming the author has set up ClearType right on their computer, I believe this may be a Firefox bug. ClearType on Windows should take care of this stuff already.
