::-moz-focus-inner

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-focus-inner CSS pseudo-element is a Mozilla extension that represents an inner focus ring of the <button> element as well as the button, submit, reset, and color types of the  <input> element.

Note: Using ::-moz-focus-inner with anything than the buttons that support it doesn't match anything and has no effect.
