Navigate to a website after installing my firefox extension

Question

I'm using Firefox Add-On SDK 1.1 to build my extension and wondering how I can open a new tab just once after the user installs my extension?

This answer Opening my page in firefox after installing the addon doesn't really help since it's not working in Add-On SDK.

Sure it helps, all you have to do is use simple-storage instead of prefs and tabs.open instead of gBrowser.addTab:

const tabs = require("tabs");
const storage = require("simple-storage");

if (storage.storage.first_run == undefined) {
    storage.storage.first_run = false;
    tabs.open("https://www.google.com");
}
