I prefer the default theme on Windows 10 as there the title bars of the other windows like Settings and Explorer use the same style, which is the color defined in 'Colors' in the settings. Using the 'Light' theme makes Firefox looking different which isn't nice. Haven't seen any other black title bar on my Mac though...
