Mozilla CSS Extensions

Mozilla supports a number of extensions to CSS that are prefixed with -moz-.

Some of these properties have been included in draft CSS specification for inclusion in the final recommendation, but are still experimental. The final standard property may be different from the current prefix implementation. Some of these non-standard properties apply only to XUL elements.

Once standardized, and the support for the un-prefixed variant added, the prefixed properties are dropped.
