"Segoe UI Light" font does not render in FireFox 7

Question

In our website "Segoe UI Light" font does not render properly in FireFox 7, while it does in IE9. What should I check?

Answer 1

Try this CSS

font-family: Segoe UI;
font-weight: lighter;

Actually font family name is Segoe UI and Light is the style (sub font, as in case of bold and italic)

This works on my side

Answer 2

This worked perfect for me. Also works on all major browsers.

font-family: "Segoe UI Light","Segoe WPC","Segoe UI",
              Helvetica, Arial, "Arial Unicode MS", Sans-Serif;

Btw, Segoe UI Light is a standalone font, not a style.
