<_moz-rs-heading> being added out of nowhere?

I really don’t know where to start. I was adding some widgets to the footer, when I realized that the first widget’s header was appearing to be a link. When I looked it up on Firebug, this is what the code looked like:

<div id="wrap">
</div>
<script src="https://www.fairtaxmn.org/nfwiu54wre/wp-includes/js/jquery/jquery.form.js?ver=2.02m" type="text/javascript">
</script>
<script src="https://www.fairtaxmn.org/nfwiu54wre/wp-content/plugins/contact-form-7/contact-form-7.js?ver=2.0.7" type="text/javascript">
</script>
<a> </a>
<div id="footer">
<a> </a>
<div id="foot">
<a> </a>
<div id="widgets">
<a> </a>
<div class="grid_3">
<h3>
<a _moz-rs-heading="">External Resources</a>
</h3>
<a> </a>
<div class="textwidget">

I have no clue where all those <a> tags are coming from, or why that first h3 header is having that tag attached to it. I can’t seem to find an answer on Google and was hoping someone on here has run across this.

The answers on Google seem to indicate a problem when the <a> tags are around a group, but I don’t have any link tags around my footer headlines. Any thoughts?
