I believe mozilla uses the freetype library in most cases... But no program is obliged to draw text in exactly the way you want. Even if you manage to intercept the text-drawing libraries of each and every program on your system you may find that it doesn't draw text in the right order to make sense when captured, or might render individual glyphs only once then draw the rest just by placing bitmaps, etc. Graphics is not console and will not behave like one.
