runtime.onBrowserUpdateAvailable

Fired when an update for the browser is available, but isn't installed immediately because a browser restart is required.

Syntax

browser.runtime.onBrowserUpdateAvailable.addListener(function() {...})
browser.runtime.onBrowserUpdateAvailable.removeListener(listener)
browser.runtime.onBrowserUpdateAvailable.hasListener(listener)

Events have three functions:

addListener(callback)
Adds a listener to this event.
removeListener(listener)
Stop listening to this event. The listener argument is the listener to remove.
hasListener(listener)
Check whether listener is registered for this event. Returns true if it is listening, false otherwise.
