Status: RESOLVED DUPLICATE of bug 1291830

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160823121617

Steps to reproduce:


In a background.js add this:

const onRemovedTab = (tabId, removeInfo) => {
  chrome.tabs.query({windowId: removeInfo.windowId}, tabs => console.log(tabs.length));
};

const onActivedTab = (activeInfo) => {
  chrome.tabs.query({windowId: activeInfo.windowId}, tabs => console.log(tabs.length));
};

chrome.tabs.onRemoved.addListener(onRemovedTab);

chrome.tabs.onActivated.addListener(onActivedTab);

You must have at least 2 tabs opened for the test.

Then you close the active tab.


Actual results:

After the tab is closed:
  * the tabs length in the onRemoved listener has not changed because the tab is still accessible with chrome.tabs.query()
  *  when the other tab is activated the tabs length in the onActivated listener has not changed because the tab is still accessible with chrome.tabs.query()



Expected results:

The closed tab should not be accessible with chrome.tabs.query()
