:-moz-system-metric(scrollbar-start-backward)

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 :-moz-system-metric(scrollbar-start-backward) CSS pseudo-class will match an element if the computer's user interface includes a backward arrow button at the start of scrollbars.

This selector is intended for use mainly by theme developers.
