Hello folks, I am using the following API to open my addon’s preferences page whenever it gets installed for the 1st time or updates to a new version.

`browser.runtime.onInstalled.addListener(onInstalledFunction);`

* * *

Problem: Recently, firefox updated to a newer version and I found the page opening again. Is there a way to make sure this page **opens only when my addon updates and not the browser**?

Thank you,  
Daniel.

reason  
An [`runtime.OnInstalledReason`](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/OnInstalledReason) value, stating the reason that this event is being dispatched.

There’s an example [runtime.onInstalled - Mozilla | MDN](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/onInstalled#examples)
