User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:15.0) Gecko/15.0 Firefox/15.0a1 Build ID: 20120603030523 Steps to reproduce: Open https://developer.mozilla.org/en/CSS/font Actual results: An ugly bitmap font is chosen for the main text (see attached snapshot). Expected results: The font matched by fontconfig should have been chosen. The fontfinder extension says: font-family (stack): "Lucida Grande","Lucida Sans Unicode",Lucida,Arial,Helvetica,sans-serif Font being rendered: "Lucida Grande" and fontconfig: $ fc-match 'Lucida Grande' Vera.ttf: "Bitstream Vera Sans" "Roman" So, Bitstream Vera Sans should be used. But instead I get a bitmap font.
What happens is that Firefox chooses "Lucida" here (contrary to what fontfinder says), because removing the "Lucida" fallback solves the problem. And indeed, "Lucida" alone is a bitmap font: $ fc-match Lucida luRS12-ISO8859-1.pcf.gz: "Lucida" "Sans" It seems that Bitstream Vera Sans is a fallback for fc-match, because Lucida Grande doesn't exist.
