Package: iceweasel Version: 38.3.0esr-1When I open https://www.google.com/fonts/specimen/Fira+Sans in iceweasel, blank glyphs are shown for this web font. Other web fonts work correctly: https://www.google.com/fonts/specimen/Crete+Round displays fine, for example.
Note I observe the same behavior with chromium, but I don't know what's the culprit so I assign it to iceweasel until somebody has more clues than me.
