Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
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.
