## Declaration

```swift
func didOpenTab(_ newTab: any WKWebExtensionTab)
```

## Parameters

## Discussion

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