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-appearance CSS property is used in Gecko (Firefox) to display an element using a platform-native styling based on the operating system's theme.

This property is frequently used in XUL stylesheets to design custom widgets with platform-appropriate styling. It is also used in the XBL implementations of the widgets that ship with the Mozilla platform.

Do not use this property on Web sites: not only is it non-standard, but its behavior changes from one browser to another. Even the keyword none does not have the same behavior on each form element across different browsers, and some do not support it at all.

[1] Not fully supported.

In addition to the -moz prefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.

[2] Only the none, button, and textfield values are supported. See the documentation on MSDN.
