# didCloseTab(_:windowIsClosing:)

Called by the app when a tab is closed to fire appropriate events with only this extension.

## Declaration

```swift
@MainActor @preconcurrency func didCloseTab(_ closedTab: any WKWebExtensionTab, windowIsClosing: Bool = false)
```

## Parameters

- `closedTab`: The tab that was closed.
- `windowIsClosing`: A Boolean value indicating whether the window containing the tab is also closing.

## Discussion

Discussion This method informs only the specific extension of the closure of a tab. If the intention is to inform all loaded extensions consistently, you should use the respective method on the extension controller instead.
