In the example link , the button perfectly creates the tabs, but when I give F5 on the page it is only the first tab. How do I keep the tabs created by the button when updating the page with F5?

You need to preserve the $scope.tabs collection.

In the following example you may notice that the collection receives a new member every time you click the Add Tab button.

I've changed the code in your example to allow values to be saved in the localStorage between sessions.

console.clear();

var app = angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);

app.directive('compileHtml', ['$sce', '$parse', '$compile',
  function($sce, $parse, $compile) {
    return {
      restrict: 'A',
      compile: function ngBindHtmlCompile(tElement, tAttrs) {
        var ngBindHtmlGetter = $parse(tAttrs.compileHtml);
        var ngBindHtmlWatch = $parse(tAttrs.compileHtml, function getStringValue(value) {
          return (value || '').toString();
        });
        $compile.$$addBindingClass(tElement);

        return function ngBindHtmlLink(scope, element, attr) {
          $compile.$$addBindingInfo(element, attr.compileHtml);

          scope.$watch(ngBindHtmlWatch, function ngBindHtmlWatchAction() {

            element.html($sce.trustAsHtml(ngBindHtmlGetter(scope)) || '');
            $compile(element.contents())(scope);
          });
        };
      }
    };
  }
]);

app.controller('TabsDemoCtrl', function($compile, $sce, $scope, $window) {

var retrievedObject = JSON.parse(localStorage.getItem('testObject'));  // Obtém do localstorage

  $scope.tabs = retrievedObject || [{"title":"Tab 01","content":"Dynamic content 1","active":true},{"title":"Tab 02","content":"<div><h1>New Tab 02 {{foo}}</h1><div ng-include=\"tab.tabUrl\"></div></div>","tabUrl":"includeFile.html","active":false}];

  $scope.removeTab = function(i) {
    console.log("Removing tab: " + i);
    $scope.tabs.splice(i, 1);
    localStorage.setItem('testObject', JSON.stringify($scope.tabs)); // Armazena no localstorage
  };

  $scope.foo = 'FOO';
  $scope.bar = 'BAR';

  $scope.addTab = function() {
    var len = $scope.tabs.length + 1;
    var numLbl = '' + ((len > 9) ? '' : '0') + String(len);

    var mrkUp = '<div>' +
      '<h1>New Tab ' + numLbl + ' {{foo}}</h1>' +
      '<div ng-include="tab.tabUrl"></div>' +
      '</div>';

    $scope.tabs.push({
      title: 'Tab ' + numLbl,
      content: mrkUp,
      tabUrl: 'includeFile.html'
    });
    
    localStorage.setItem('testObject', JSON.stringify($scope.tabs));  // Armazena no localstorage
  };
});

app.controller('IncludeFileCtrl', function($scope) {

  console.log('IncludeFileCtrl');

  $scope.title = "Include File Title";
});
