Can you please compare with an upstream tarball?
We switched Firefox to use gtk3 instead of gtk2 now on Tumbleweed. Firefox upstream is already using gtk3 for quite some time. We need to find out if that is an openSUSE or Mozilla issue.

I tested the upstream version (51.0.1) on a fresh installed Leap 42.2, the result is the same - dark theme was not applied. 

So, yes, it's an upstream issue.

The ability to set a "Global dark theme" has been removed from gnome-tweak-tool (v 3.30). Setting the theme to "Adwaita dark" from the same tool also applies it correctly for firefox (if ffx's theme is set to "Default"). So this is considered fixed now. Please feel to reopen if this is not the case. Thanks for your report!
