hey Dao, is this worth blocking on?
(In reply to Mike Taylor [:miketaylr] from comment #1) > hey Dao, is this worth blocking on? Tracking yes. Blocking probably not, but let's try hard to fix this.
mstange, could this be a widget::cocoa bug? ntim tested -moz-appearance:separator with both orientations on Mac in attachment 8966788 [details], so I'm a bit confused. Maybe the separator is rendered but with the same color as the toolbar, making it invisible?
The inspector shows that the width of the separator element is zero. If I set the width to 1px, for example, then the separator shows up, and its color is sufficiently different from the toolbar color. It's probably worth setting a non-zero size for NS_THEME_SEPARATOR in nsNativeThemeCocoa::GetMinimumWidgetSize.

trying to determine how serious this is.
It's a trivial fix, I'll do it.
