Bug#747317: iceweasel: missing/buggy support for @font-face (breaks twitter and others)

Package: iceweasel
Version: 24.5.0esr-1
Severity: normal


@font-face is supposed to be supported, as documented in:

but even the live example there doesn't work in iceweasel: one gets a
non-bold, default font instead.

For websites pointing at online fonts, using characters from some private
Unicode plane, that means an “unknown glyph” character instead of
icons/buttons, which makes the use of websites like twitter or gitlab
quite painful.

I'm attaching twitter snapshots (ok = chromium, ko = iceweasel). You can
check what happens with gitlab on the live demo site:

The issue also happens with the version in wheezy and in experimental,
with a brand new user and no custom configuration whatsoever (even
though I'm reporting from my regular user session here, so with some
extensions enabled).
