1563399 - Firefox doesn't obey Xfce DE font anti-aliasing settings.

Status: UNCONFIRMED

(Core :: Graphics: Text, defect, P3)

Description

[Sergio]

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

Fedora 30 Xfce
Summary:
Xfce has a 'appearance settings' which includes fonts and anti-aliasing. Every application I have installed follow its settings but Firefox ignores it and use the system-wide fontconfig settings or, if I had one, probably would also use local fontconfig settings.

What did you do? (steps to reproduce):
Simply install Firefox and open it inside Xfce DE.

Actual results:

In my case, in which the decent font settings are full hinting and rgb sub-pixel rendering and the system wide default one is slight hinting and no sub-pixel rendering, Firefox's interface was not only terribly bad looking, it was almost unusable after some time staring at it.

I won't post a screenshot because I would have to revert my system font settings but this is totally reproducible and well known. It seems for quite some time already, as seen by this old bug #1187198

Expected results:

Firefox should ideally simply use the DE font settings. I suppose it's something pretty standard as other applications use them.
