Keep current Bootstrap tab active after page reload without jumping to first one between

I'm using Bootstrap pills in my app:

<div class="container">
  <ul class="nav nav-pills">
    <li class="active"><a data-target="#home" data-toggle="tab">Home</a></li>
    <li><a href="#about" data-toggle="tab">About</a></li>
    <li><a href="#contacts" data-toggle="tab">Contacts</a></li>
  </ul>
</div>

<div class="tab-content">
  <div class="tab-pane active" id="home">Home</div>
  <div class="tab-pane" id="about">About</div>
  <div class="tab-pane" id="contacts">Contacts</div>
</div>

In order to stay on the same tab after page reload I use the following function:

$(function() {
  $('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
    localStorage.setItem('lastTab', $(this).attr('href'));
  });
  var lastTab = localStorage.getItem('lastTab');
  if (lastTab) {
    $('[href="' + lastTab + '"]').tab('show');
  }
});

The problem is that after page reload, the first tab becomes active for 1 second and then it jumps to the actual active tab. Can I keep current tab without this 'jumping'?

Simple answer: just remove the ACTIVE CLASS from the default tab and its contents.

<div class="container">
  <ul class="nav nav-pills">
    <li><a data-target="#home" data-toggle="tab">Home</a></li>
    <li><a href="#about" data-toggle="tab">About</a></li>
    <li><a href="#contacts" data-toggle="tab">Contacts</a></li>
  </ul>
</div>

<div class="tab-content">
  <div class="tab-pane" id="home">Home</div>
  <div class="tab-pane" id="about">About</div>
  <div class="tab-pane" id="contacts">Contacts</div>
</div>

In the Javascript file in the script tag:

$(function() {
    var lastTab = localStorage.getItem('lastTab');
    if (lastTab) {
      $('[data-target="' + lastTab + '"]').tab('show');
    }
    $('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
      localStorage.setItem('lastTab', $(this).data('target'));
    });
});

This line:

$('[href="' + lastTab + '"]').tab('show');

must be changed in:

$('[data-target="' + lastTab + '"]').tab('show');

You cannot refer to href but to data-target.

The same apply for: localStorage.setItem.....

The fixed code (jsfiddle):

$(function() {
  var lastTab = localStorage.getItem('lastTab');
  $('.container, .tab-content').removeClass('hidden');
  if (lastTab) {
    $('[data-target="' + lastTab + '"]').tab('show');
  }
  $('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
    localStorage.setItem('lastTab', $(this).data('target'));
  });
});

    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<div class="container hidden">
    <ul class="nav nav-pills">
        <li><a data-target="#home" data-toggle="tab">Home</a></li>
        <li><a data-target="#about" data-toggle="tab">About</a></li>
        <li><a data-target="#contacts" data-toggle="tab">Contacts</a></li>
    </ul>
</div>

<div class="tab-content hidden">
    <div class="tab-pane" id="home">Home</div>
    <div class="tab-pane" id="about">About</div>
    <div class="tab-pane" id="contacts">Contacts</div>
</div>

The answer is as simple as ABC.

I just needed to remove class="active" from the first <li></li> tag:

<li><a data-target="#home" data-toggle="tab">Home</a></li>
