Uma ação de página é ícone clicável dentro da barra de endereço do navegador.

 

Pode ouvir cliques no ícone, ou especificar uma janela (popup) que será aberta quando o ícone for clicado.

If you specify a popup, you can define its contents and behavior using HTML, CSS, and JavaScript, just like a normal web page. JavaScript running in the popup gets access to all the same WebExtension APIs as your background scripts.

You can define most of a page action's properties declaratively using the page_action key in your manifest.json, but can also redefine them programmatically using this API.

Page actions are for actions that are only relevant to particular pages. If your icon should always be available, use a browser action instead.
