CSS Browser Extensions

Firefox CSS Extensions / Mozilla CSS Extensions

CSS extensions are style properties that web browsers support but are not (yet) a part of the official CSS specification. They are defined by a dash and then a browser keyword at the front of each property. And the extensions only work in the browsers they are defined in.

Firefox CSS extensions are CSS style properties that work in Mozilla browsers. Many of these style properties are a part of CSS 3, but they will only work in the browsers if you use the extension property.

Also, many of these properties are used more for building Firefox add-ons than for web pages.
