Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The mozInnerScreenY property of the Window interface returns the Y coordinate of the top-left corner of the window's viewport, in screen coordinates.
Note: This coordinate is reported in CSS pixels, not in hardware pixels.
The window.mozInnerScreenY property is a floating point, read-only value; it has no default value.
This feature is not part of any current specification. It is not on track to become a standard.
