How to fix TypeError: browser is not defined?

Question

我对 onclick 浏览器操作有疑问。一直显示 TypeError: browser is not defined if I do put in try catch 尝试手动插入 firefox 控制台，但仍未定义是否成功。使用火狐 55。如何克服这个问题？

console.log("Start 1")
function run(){console.log(1)}
browser.browserAction.onClicked.addListener(run);

var interval1Id = setInterval(function(){

 var id = document.querySelector(".myclass").id

 document.getElementById('m1).contentWindow.document.getElementById(id).click();
 var newDate = new Date();
   console.log("Function executes at : " +newDate ) 
},10000);

Output of background script goes to specific Debug page, not to output of firefox console . Extensions-> Debug Extension -> Allow debugging-> Debug on extensions. New console outputs, where everything comes to display Browser variable only supported in Debug console, not in developer tools console
