Count Chrome windows and tabs

// Run in console in an option window for an extension with tab privileges, IE "Too many tabs"
chrome.windows.getAll({populate:true},function(windows){
var t = 0;
var w = 0;
  windows.forEach(function(window){
  w++;
    window.tabs.forEach(function(tab){
      //collect all of the urls here, I will just log them instead
      //console.log(tab.url); // Uncomment to have each tab URL printed in the log.
      t++;
    });
  });
  console.log("Total tabs: "+t+" in "+w+" windows");
});
