Using Cookies to make action stay on browser refresh or closed/Re-open

Question

Hello everyone!
I have this peice of JQuery:
<script type="text/javascript">
$(document).ready(function() {
$('#tab1').on('click',function(){
    $('ol li span').removeClass(function() {
          return $(this).attr('class');
        }).addClass('default');
$('#tab2').click(function(){
    $('ol li span').removeClass(function() {
          return $(this).attr('class');
        }).addClass('style2');
$('#tab3').click(function(){
    $('ol li span').removeClass(function() {
          return $(this).attr('class');
        }).addClass('style3');
</script>
Html:
<a id="tab1" href="#">Sample</a>
<a id="tab2" href="#">Sample</a>
<a id="tab3" href="#">Sample</a>
As you can see I simply need to apply a particular style to list in a span when a tab with the specific ID is clicked, the issue is Cookies which I do not eat often.
How do I make this stay? If the user selects/clicks  a particular tab I would rather the style remain on refresh or browser close and if nothing is selected when the page is first visited than the default applies.
By the way I am using ID on the link (anchor) because it is doing something unrelated to this post.
I can find my way around applying a single style (default) but in this case there are different styles for each tab clicked.
This I do not know.
Thanks for reading my sob story.

This is likely caused by one of the installed extensions and quick_start in the chrome URL should tell which extension in this case.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

There are other things that need your attention.
Please update to the current Firefox 31 release.

The Firefox 14 version that you currently run is no longer supported with security updates.
*It is important to update Firefox and add-ons to the latest version to get all security fixes.
