i installed also the gnome theme... the ugly scroll bar appeared but not in every place where it should be and sometimes it disappeared completely. something is utterly wrong with it. and it seems to be within the adwaita theme, because I dont have this problem under 14.04 only in xenial.
my workaround was downgrading to firefox 45 (gtk2) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575896 Title: Scrollbar thumb not drawn in firefox 46 (gtk3?)
