Embora as APIs sejam baseadas no Chrome devtools APIs, ainda existem muitas funcionalidades que ainda não estão implementadas no Firefox, e por isso, não estão documentadas aqui. Para ver quais as funcionalidades que estão atualmente em falta, por favor, consulte Limitações das APIs de devtools.

The devtools.panels API lets a devtools extension define its user interface inside the devtools window.

The devtools window hosts a number of separate tools - the JavaScript Debugger, Network Monitor, and so on. A row of tabs across the top lets the user switch between the different tools. The window hosting each tool's user interface is called a "panel".

With the devtools.panels API you can create new panels in the devtools window.

Like all the devtools APIs, this API is only available to code running in the document defined in the devtools_page manifest.json key, or in other devtools documents created by the extension (such as the panel's own document). See Extending the developer tools for more.

1. This event is only fired when the user switches between sidebar panes, not when the user switches between devtools panels. See bug 1412317.

2. The expression must evaluate to a JavaScript object or a DOM node, or nothing is shown in the sidebar.

3. The expression must evaluate to an object that can be serialized to JSON, or nothing is shown in the sidebar. In particular, JavaScript cyclic objects and DOM nodes are not supported. See bug 1403130.
