> **Note :** Cette méthode ne peut pas être utilisée en mode Navigation privée - elle renvoie toujours un tableau vide. Pour plus d'informations, voir {{bug(1329304)}}.
## Syntaxe
```js
var page = browser.extension.getBackgroundPage()
```
### Paramètres
Aucun
### Valeur retournée
`object`. [Window](/fr/docs/Web/API/Window) de la page d'arrière plan.
## Compatibilité du navigateur
{{Compat("webextensions.api.extension.getBackgroundPage")}}
## Exemples
Supposons un [script d'arrière plan](/fr/Add-ons/WebExtensions/Anatomy_of_a_WebExtension#Background_scripts) définisse une fonction `foo()`:
```js
// background.js
function foo() {
console.log("I'm defined in background.js");
}
```
Un script exécuté dans un [popup](/fr/Add-ons/WebExtensions/Anatomy_of_a_WebExtension#Browser_actions_2) peut appeler cette fonction directement comme ceci :
```js
// popup.js
var page = browser.extension.getBackgroundPage();
page.foo(); // -> "I'm defined in background.js"
```
