In spite of IE's shortcomings fonts look better in IE (font smoothing?).

1 Why doesn't FF and others do whatever it is that IE is doing in this regard?

2 The font on this site looks good in FF! This is probably a normal web font (Arial?) made to look better with css? Normally I can swipe a look at the css page to see how the font etc has been dictated but in the following site I can't understand the style sheet or haven't sussed which one!!

can anyone help pls
