Removing Mootools and JCaption code in Joomla

As you know that Joomla will automatically includes Mootools library and some unneeded javascript to every page of your site, you might already familiar with this line of code:

Joomla will add this code to every page by default and there is no option or configuration to prevent Joomla doing this. I found a good blog post to remove JCaption in Joomla 2.5 at but I think those solutions are complicated for me. And what I need is to completely remove Mootools library and only use jQuery library on my website so that my website will run faster enough. so here are the steps to remove Mootools library and also JCaption code from your page:

Removing Mootools and unneeded javascript from head tag

  1. open /libraries/joomla/document/html/renderer/head.php . this file is responsible to render the head tag of your pages 
  2. find this line of code
  3. We will add some codes to ignore these javascript files: mootools-core.js, mootools-more.js, core.js, tabs-state.js, caption.js, jquery-noconflict.js, jquery-migrate.min.js , I found this solution from Brad Markle w/,  ok so update these lines of code so that it will looks like:

Removing JCaption code

Now we will remove these lines of code:

  1.  open/libraries/cms/html/behavior.php and find this function :
  2. and then comment the code which adds the caption.js to the head tag and also comment the code which attach JCaption code to the page:


and that’s it, now your joomla site will load a little bit faster without Mootools

Put this code at the top of your template’s index.php file. Basically this code will remove all script files and javascript code from head tag and then we add our js files using addScript method.
