Got this from Joomlaworks

This post is for those who are experiencing javascript issues (errors or conflicts) when using the latest "Frontpage Slideshow" module (v1.6) on Joomla! templates that heavily rely on Mootools (mainly the RocketTheme templates).
So, if you already have such a template and furthermore, if you have installed some other Joomla! or Mambo extension that uses Mootools as well, you can get javascript errors or conflicts. But wait! This is actually normal and it all depends on how Mootools works. You see, calling the Mootools library multiple times (not to mention calling different version of the Mootools library on the same template!) causes it to crash in many situations.
So what do we do? The best solution is to call the full Mootools library on your template's head.../head tags and comment it out/delete it from your extensions and your template.
That way you will only include the Mootools library once (=less weight for your webpage too) and all your Mootools-based extensions AND your template's "tools" or functionality will operate properly.
So download the full Mootools library

unzip it, create a folder called "js" inside your current template and transfer in there the extracted mootools.v1.11.js file. After that, add this code between the head.../head tags in your template:
*check the above Joomlaworks link for the snippet of code. Sorry*
Possibly this works for FireBoard as well.
