This non-standard property is not recommended. Authors should generally find an alternative way to accomplish the same task while adhering to all best practices, or simply do without it if it is unimportant.

The CSS -moz-box-shadow Mozilla extension property was used as a substitute to the box-shadow property. This Mozilla extension is only implemented in Firefox 3.5 (Gecko 1.9.1) and before, and since Firefox 4.0 (Gecko 2.0), it no longer supports this property. Instead, Firefox supports the box-shadow property.


See the values for box-shadow.
