This is a problem with the material design icon set. Turns out there's about 73 icons that use <use xlink:href, which isn't a thing we support, and needs to be fixed in the original sources.

These icons (at least) from the default and other sets don't appear in Firefox (39.0):
event-seat, icons-b, flight-land, icons-d, flight-takeoff, gif, indeterminate-check-box, av:airplay, av:b, av:d, av:forward-10, av:forward-30, av:forward-5...and more...from the iron-icons demo page (and other usages).
