992559 - Helvetica Neue font-weight:300 should be Light instead of Thin

Status: RESOLVED DUPLICATE of bug 931426

(Core :: Graphics: Text, defect)

Description

[Cody 'codeman38' Boisclair]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

Create a page with the following CSS style defined, and load it in Firefox on Mac OS X:

    font-family: "Helvetica Neue"; font-weight: 300


Actual results:

The font style that is displayed is Helvetica Neue Light. In the font file included with OS X, this font has a 'usWeightClass' value of 300.


Expected results:

The font that is displayed is Helvetica Neue Thin. In the font file included with OS X, this font has a 'usWeightClass' value of 250.

This style is slightly thinner, and thus harder to read for body text, than the expected style.

Argh, sorry, out of habit from other bug trackers, I accidentally swapped the Actual and Expected results when I was filing the bug.

The *expected* result is that it should use Light (300). The *actual* result is that it uses Thin (250).

Core :: Graphics: Text probably, jfkthame will know for sure.

Looks like a dupe of bug 931426 to me, so this should be fixed in Nightly.
