Fired when a new window, or a new tab in an existing window, is created to host the target of a navigation. For example, this event is sent when:
- the user opens a link in a new tab or window
- a web page loads a resource into a new tab or window using
window.open()
(but note that the event is not sent if the browser's popup blocker blocks the load).
The event is not sent if a tab or window is created without a navigation target (for example, if the user opens a new tab by pressing Ctrl+T).
If this event is fired, it will be fired before webNavigation.onBeforeNavigate
.
