Steps to reproduce the problem:
1. make a background.js file for a chrome extensions
2.  use this code

chrome.browserAction.onClicked.addListener(function (activeTab) {
  chrome.tabs.query({ currentWindow: true, active: true }, function (tabs) {
    chrome.tabs.sendMessage(tabs[0].id, { greeting: "hello" }, function (response) {
      console.log(response.farewell);
    });
  });
});

3. click on the browser extension button and debug this code, you will see the 0 length array

What is the expected behavior?
to have the current tab returned

What went wrong?
0 length array where I expected the current active tab

Did this work before? N/A
