When light text is shown on a dark background on a web page, Firefox for Mac renders the font too bold. This only applies to the Mac version, the windows version renders fine. This problem was also occurring with Safari on the Mac, however it was corrected by adding:
to the css code of the site.
Is there a similar code that will do the same for Firefox Mac? Already tried
but that is no solution with this font (DIN)
did you try setting the font weight? 200,300,400 etc
