Angular.JS on Firefox Junk after document element error - angularjs

Question

When I test my index.html on Firefox with console.log it reads a strange error that says. I can't make the oage run on Google Chrome or IE.
junk after document element
This error is caused by the main.html page
<h1>This is my main</h1>
<h3>Scope value: {{ name }} </h3>
I'm just learning angular.js, in fact my code is exactly like this tutorial I was following, but I can't figure out why is not working. Can anyone point me in the right direction and tell me:
Why am I getting the console log error: Junk after document error, and
why can't I make ngview and templateURL work on my site?
Thanks!
My Plnkr Example
App.JS:
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'pages/main.html',
controller: 'mainController'
})
.when('/second', {
templateURL: 'pages/second.html',
controller: 'secondController'
})
});
myApp.controller('mainController', ['$scope', '$log', function($scope, $log) {
$scope.name = 'Main';
}]);
myApp.controller('secondController', ['$scope', '$log', function($scope, $log) {
$scope.name = 'Second';
}]);
Index.HTML
<header> <nav class="navbar navbar-default"> <div class="container">
<div class="navbar-header">
<a class="navbar-brand" href="/">AngularJS</a>
</div>
<ul class="nav navbar-nav navbar-right">
<li><i class="fa fa-home"></i>Home</li>
<li><i></i>Second</li>
</ul> </div> </nav> </header>
<div class="container">
<div ng-view></div>
</div>
Main.HTML
<h1>This is my main</h1>
<h3>Scope value: {{ name }} </h3>
Second.HTML
<h1>This is my second</h1>
<h3>Scope value (on second page): {{ name }} </h3>

Answer 1

the code does not run on IE or Chrome cause they don't have a built in localhost feature. Firefox does.
Regarding the Error, I am not 100% sure but I believe that it has to do with Angular HTML format support in the browser itself. I am taking the same course now and facing the same issue. But the app is working fine except for those errors in Firefox.
Chrome: no errors.
MS Edge: no errors.
IE: no errors
===========================
update
Try using Brackets text editor, and use the Live Preview feature.
Open the Index.HTML page in Brackets and hit the button on the top right corner.
