runtime.onInstalled

Fired when the extension is first installed, when the extension is updated to a new version, and when the browser is updated to a new version.

Note that runtime.onInstalled is not the same as management.onInstalled. The runtime.onInstalled event is fired only for your extension. The browser.management.onInstalled event is fired for any extensions.

Syntax

browser.runtime.onInstalled.addListener(listener)
browser.runtime.onInstalled.removeListener(listener)
browser.runtime.onInstalled.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)

Checks whether a listener is registered for this event. Returns true if it is listening, false otherwise.
