runtime.onBrowserUpdateAvailable

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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

Syntax

browser.runtime.onBrowserUpdateAvailable.addListener(listener)
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.
