To close, reload and duplicate tabs, you need to use the remove(), reload() and duplicate() methods respectively. The important thing to note about these methods is that you do not necessarily need to mention the tabs permission in the extension manifest in order to use them in the extension.
All three of these methods work in the same way. Let’s look at some example extension code that reloads a tab. The first thing to do would be to get hold of the current tab, after which you would call the reload() method. So, in the background script you would write something like so:
chrome.tabs.query({
currentWindow: true,
active: true
// Get the current tab
}, function(tab){
// Remove the tab
chrome.tabs.remove(tab[0].id);
chrome.browserAction.onClicked.addListener(function() {
chrome.windows.create({
'url': url_list,
'incognito': true
