This document lists an onSuspend event:

Clean-up before app closes

The app runtime sends the onSuspend() event to the event page before unloading it. Your event page can listen out for this event and do clean-up tasks before the app closes.

Once this event is fired, the app runtime starts the process of closing the app: all events stop firing and JavaScript execution is halted. Any asynchronous operations started while handling this event are not guaranteed to complete. Keep the clean-up tasks synchronous and simple.

chrome.runtime.onSuspend.addListener(function() { // Do some simple clean-up tasks. });

This document says the onSuspend is also available for extensions
