firefox adding unwanted content through tiny mce

Hello All,

Strange issue and I can’t seem to find any answer to it.
When I click the update button in the dashboard page editor a table of contents is added to the page. The following code is added.

<div id="bikatoc" style="display: none;"><a class="control">Close</a>
<div class="toc">
<ul>
	<li class="toc-h2"><a href="#toc0">Newsroom</a></li>
	<li class="toc-h3"><a href="#toc1">Nutrition</a></li>
	<li class="toc-h3"><a href="#toc2">Brochures</a></li>
	<li class="toc-h3"><a href="#toc3">Press Releases</a></li>
</ul>
</div>
</div>

This adds a visual column to the page that is extremely unwanted. This code is only added in Firefox. Trying the same steps in Chrome, IE, and Safari do not create the same chunks of code being added.

Each time I hit the update button another chunk of code will be added. I have no idea what is going on and this is making development a real beast.

All help is welcome and wanted. Thank you.
