Em ordem para testar as novas funcionalidades, a Mozilla publica uma versão de testes do navegador Firefox, Firefox Nightly, diariamente. Funcionalidades experimentais, for example implementations of proposed Web platform standards, are available. This page lists features that are in Nightly versions of Firefox along with information on how to activate them, if necessary. You can test your Web sites and applications before these features get released and ensure everything will still work with the latest Web technology capabilities.

+ +

To test these experimental features, you need to download Firefox Nightly or Firefox Developer Edition.
