Description Matěj Cepl 2016-01-06 13:30:27 UTC 
Created attachment 1112160 [details]
screenshot of the Firefox inspector showing the problem

Description of problem:
When entering the Disqus discussion on http://www.firstthings.com/web-exclusives/2016/01/free-university-orthodoxy (I am not sure how to save this page so that we would have attached here reproduction data set) the comment text is in fact displayed with "Nimbus Roman No9" Type1 font (see attached screenshot of the Firefox inspector on the page) when the Computed font-family is "Georgia,Times,serif".

However, when I run

fc-match Georgia

on the command line, I get

DejaVuSerif.ttf: "DejaVu Serif" "Book"

which is a way more useful suggestion. Why Firefox doesn't follow fontconfig, where is the problem?

Version-Release number of selected component (if applicable):
Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0


How reproducible:
100% on my computer

Steps to Reproduce:
1.open the page and activate Disqus comments
2.
3.

Actual results:
using hard to read Nimbus Type1 font instead of antialiased nice TrueType DejaVu Serif.
Comment 2 Matěj Cepl 2016-01-06 14:29:44 UTC 
Adding this to /etc/fonts/local.conf made the problem go away:

<alias>
    <family>Georgia</family>
    <accept>
      <family>DejaVu Serif</family>
    </accept>
</alias>

But it is not right, because fc-match was saying the same before already. Why Firefox does not give the same answer as fc-match?
Comment 3 Matěj Cepl 2016-01-06 14:32:52 UTC 
BTW, using firefox from the package firefox-38.5.0-3.el7_2.x86_64

Actually I was wrong in the comment 1 ... this local.conf modification helped to the upstream binary for Aurora (Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0), but our RHEL Firefox 38.5.0 still manifests the same issue (Font inspector shows Nimbus font and it really looks like Type1 non-antialiased font).

AFAIK ti may be fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=1167284
Please reopen if you see that in ESR45.
