# didOpenTab(_:)

Should be called by the app when a new tab is opened to fire appropriate events with all loaded web extensions.

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

## Parameters

`newTab`

The newly opened tab.

## Discussion

This method informs all loaded extensions of the opening of a new tab, ensuring consistent understanding across extensions.

If the intention is to inform only a specific extension, you should use the respective method on that extension’s context instead.
