Javascript code too slow in Firefox extension using Storage service

Question

I\'m running the following javascript code in firefox extension

highlightLinks: function(e) {

  var anchors = e.target.getElementsByTagName(\"a\");
  let file =         


        

Answer 1

first tip, altough it won't save too much time, is not using anchors.length in the condition of the for-loop. better use:

for(var i = 0, num = anchors.length; i < num, i++) {...}
