@mozilla.org/gfx/fontlist;1

 The nsIFontList interface provides an application the  
 necessary information so that the user can select the font to use 
 as the default style sheet. This is used if the style sheet is 
 missing or does not specify a font.
 <P>Font lists are specified per language group.
