Bug 1243226 is marked as fixed on 45, but apparently this is still broken on 45?

Same here. Web pages are OK in 45, but chrome level text has picked some weird fonts. And set gfx.font_rendering.fontconfig.fontlist.enabled to false solves this.

I'm on Arch Linux. This is the only font-related changes I've made to the system besides installing a lot of fonts. These are all the fonts I've installed (obtained via pacman -Qo /usr/share/fonts/):

I also noticed some characters rendering incorrectly both in the UI and in web pages. Only on Firefox.

This issue should have affected multiple users, and still exists in Firefox 46b5.
Will someone look into this?

Interesting... The content has the right font matching but the chrome doesn't... Is there any difference for font matching between chrome and content?

Comment 12

[Xidorn Quan [:xidorn] UTC+10]

Looks like it is an issue from the special keyword value of "font" property. This issue is reproducible in content with "font: message-box".

It seems to me this has been fixed in this push: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=ada58caa17b4f4c5788b89ff28787ff5a774089f&tochange=21ad62cfce1989cfb2881db01bacc236cc5917f6

It should be bug 1245811, which has been uplifted to beta 47. And it seems to me the issue here is not reproducible in Firefox 47b8.
