{{AddonSidebar()}}

Lancé lorsque le contenu de l'onglet est remplacé par un onglet différent (généralement précédemment pré-rendu).

## Syntaxe

```js
browser.webNavigation.onTabReplaced.addListener(
  listener,                   // function
  filter                      // optional object
);
browser.webNavigation.onTabReplaced.removeListener(listener)
browser.webNavigation.onTabReplaced.hasListener(listener)
```

Les événements ont trois fonctions :

- `addListener(callback)`
  - : Ajoute un écouteur à cet événement.
- `removeListener(listener)`
  - : Arrêtez d'écouter cet événement. L'argument `listener` est l'écouteur à supprimer.
- `hasListener(listener)`
  - : Vérifiez si `listener` est enregistré pour cet événement. Renvoie `true` s'il est écouté, sinon `false`.

## Syntaxe addListener
