runtime.onBrowserUpdateAvailable

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. 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.removeListener(listener)

Events have three functions:

addListener(callback): Adds a listener to this event.
