We intend to ship unicode-range in Firefox 44. It has been implemented for
non-Linux platforms for over a year now behind the
"layout.css.unicode-range.enabled" pref. The pref has been enabled by
default for Nightly and Developer builds but not for Beta and Release
builds. Once changes to Linux font handling have been enabled (bug
1180560), this feature will now be available on all platforms.
Safari, Internet Explorer and Chrome have all implemented this. However,
font loading behavior is not consistent across implementations. Safari and
Internet Explorer ignores the unicode-range value when deciding which fonts
to download. Firefox and Chrome only download those fonts for which the
unicode-range matches the characters used within content.
Bug to enable unicode-range: 1119062
Spec definition:
CSS3 Fonts specification (CR)

One question that, the current nightly is Firefox 45, and I suppose
you are not going to uplift the enabling bug, so you probably meant
shipping in Firefox 45?
