In most cases it is not necessary to have mootools.js framework included in every Joomla! page since this affects performance and can raise conflits when you will try to use next version of mootools framework in one of your components (for example mootools 1.11 and mootools 1.2 are NOT fully compatible). In this case it is useful to remove mootools from Joomla header and add it only when needed.
