The goal is to open a URL in the active tab. If one does not exist, we should open a new tab for it.

open_in_active_tab.js

function openURLInActiveTab(url){
	if (tabs.activeTab.url === undefined) {
		tabs.open({url: url, onOpen: function onOpen(tab) { console.log("[GLOBAL]: Opened tab: " + tab); tab.activate(); tab.url = url; }});
	}
	else {
		tabs.activeTab.url = url;
	}
}
