Extensões de Navegador

This translation is incomplete. Please help translate this article from English

As extensões podem ampliar e modificar a capacidade de um navegador. As extensões para Firefox são criadas utilizando a API de WebExtensions, um sistema de navegador cruzado para desenvolver extensões. Em grande medida, o sistema é compatível com a API de extensão suportada pelo Google Chrome, Opera e W3C Draft Community Group.

As extensões escritas para estes navegadores irão na maioria dos casos ser executadas no Firefox ou Microsoft Edge com apenas algumas alterações. A API também é totalmente compatível com os multiprocessos do Firefox.

Se tiver ideias ou questões, ou precisar de ajuda para migrar um extra legado para utilizar as APIs de WebExtensions, pode contactar-nos em lista de discussões dev-addons ou #webextensions no IRC
