-moz-scrollbar-thumb-proportional

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.

Note: Since Firefox 58, this media feature is no longer available to web content — it is only available internally (e.g. to XUL / chrome code). See bug 1396066 for more details.

If the device's user interface displays the thumb of scrollbars proportionally (that is, sized based on the percentage of the document that is visible), this is 1. Otherwise it's 0.
