browserAction

Ajoute un bouton à la barre d'outils du navigateur.

Une action du navigateur est un bouton dans la barre d'outils du navigateur.

You can associate a popup with the button. The popup is specified 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, but its global context is the popup, not the current page displayed in the browser. To affect web pages you need to communicate with them via messages.

If you specify a popup, it will be shown — and the content will be loaded — when the user clicks the icon. If you do not specify a popup, then when the user clicks the icon an event is dispatched to your extension.

You can define most of a browser action's properties declaratively using the browser_action key in the manifest.json.

With the browserAction API, you can:

  • use browserAction.onClicked to listen for clicks on the icon.
  • get and set the icon's properties — icon, title, popup, and so on. You can get and set these globally across all tabs, or for a specific tab by passing the tab ID as an additional argument.

Types

browserAction.ColorArray
An array of four integers in the range 0-255 defining an RGBA color.
browserAction.ImageDataType
Pixel data for an image. Must be an ImageData object (for example, from a <canvas> element).
