Details

nsDeviceContext::FindScreen[1] attempts to get a handle on the native screen by using getNativeData on the PuppetWidget with NS_NATIVE_WINDOW.

Unfortunately, PuppetWidget doesn't support NS_NATIVE_WINDOW. It supports NS_NATIVE_SHAREABLE_WINDOW, but this is not something that all platforms support (as far as I can tell).

Because it fails to get the native screen for the widget, it defaults to getting the primary screen. This means the screen data will be incorrect if the browser is on a screen other than the primary screen.
