uncaught exception: [Exception… “Not enough arguments” (NS_ERROR_XPC_NOT_ENOUGH_ARGS)

I was testing my web application on FireFox5 , I faced “not enough arguments” issue. During investigation what I found is while opening the page we are hitting actual issues inside ‘addEventListener’ function. I searched web around behavior of ‘addEventListener’ in firefox and found that it expect third argument as well so I replaced below code locally and it worked for me =)

addEventListener(“load”, function(event) {
      _init();
);

with

addEventListener(“load”, function(event) {
      _init();
},false);
