1278046 - Firefox 47 ignores Global Dark Theme option being enabled

Status: RESOLVED DUPLICATE of bug 1272332

(Core :: Widget: Gtk, defect)

Description

[u552789]

Attachment: Firefox_Ignoring_Global_Dark_Theme.png

I had Firefox 46.0.1 installed previously which worked fine and when having the Global Dark Theme enabled was, well, dark, as I like it. However after upgrading to Firefox 47 I have found that Firefox is all completely white, it looks as it would if the Global Dark Theme option in the gnome-tweak-tool were disabled, which it is not, and it is the only application behaving as such. I am running Ubuntu GNOME 16.04 with GNOME 3.20. I have attached a screenshot of what it looks like (though I have blacked out some private stuff).

I initially reported this issue here but thought I should also file a report upstream: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1589076

If this started with 47, I'm fairly sure the difference is a result of GTK changes. Martin/Karl, do you have ideas about how/why this happened?
