Firefox 44 breaks fontconfig (yet again)

[Andrej Shadura]

I have a fontconfig setup to use TeX Gyre family fonts (and related) instead of the Microsoft fonts from ttf-core-fonts, and I have successfully used such a setup until some of the Firefox updates in the past broke it. I played with my config and found a fix, and it worked until Firefox 44, when that broke again.

See the screenshots for the reference. Non-Latin characters are displayed using the wrong font, even a serif one, which isn't even close to what I have in the config. Importantly, no other apps broke.

Any ideas how can that be fixed?

I also have 30-metric-aliases.conf enabled:

The <div> on the screenshot has the following style set:

font-family: helvetica,arial,sans-serif;

FF 43 more or less correctly selects Nimbus and TeXGyre font for it:

FF 44 selects something else.
