The Mozilla community has created and spearheaded the development of various specifications for languages that are used in Mozilla projects and can be used by others as well. If you would like to suggest other specifications to feature here, please let us know.

• JavaScript

  JavaScript is a small, lightweight, object-oriented, cross-platform scripting language that was pioneered by the Netscape browser and is now an industry standard called ECMAScript that is supported by the Mozilla community and other browser vendors.

• XBL

  The XML Binding Language (XBL) is used to bind elements to scripts, style sheets, event handlers, and other elements. Bindings can be stored in separate documents allowing the behavior of elements to be changed without complicating the markup itself.

• XUL

  The XML User Interface Language (XUL) is used to build feature-rich cross platform applications and add-ons that extend the functionality of existing Mozilla-based programs. Web developers will learn XUL quickly and can start building applications right away.
