You need to modify getBreadcrumbPath() in app/code/core/Mage/Catalog/Helper/Data as links are not added to the breadcrumb array by default.

Do this with a rewrite that would look like

...

<helpers>

    <catalog>

        <rewrite>

            <data>[Vendor]_[ModuleName]_Helper_Catalog_Data</data>

        </rewrite>

    </catalog>

</helpers>

...

in your config.xml and the following would be the rewritten class

class [Vendor]_[ModuleName]_Helper_Catalog_Data extends Mage_Catalog_Helper_Data

{

    public function getBreadcrumbPath()

    {

        parent::getBreadcrumbPath();

        if (array_key_exists('product', $this->_categoryPath)) {

            $this->_categoryPath['product']['link'] = $this->getProduct()->getProductUrl();

        }



        return $this->_categoryPath;

    }

}

Observe the proper event, perhaps something similar to (just guessing the event) core_block_abstract_to_html_before, (but perhaps something that would be less often observed) with a custom observer, similar to:

       <core_block_abstract_to_html_before>

            <observers>

                <df2k2_update_breadcrumb>

                    <class>df2k2_page/observer</class>

                    <method>updateBreadcrumbLink</method>

                </df2k2_update_breadcrumb>

            </observers>

        </core_block_abstract_to_html_before>

Observer Class

 public function updateBreadcrumbLink(Varien_Event_Observer $observer)

 {



        $breadcrumbsBlock = $observer->getEvent()->getBlock();



        if ($breadcrumbsBlock instanceof Mage_Page_Block_Html_Breadcrumbs) {

           // Get the block, get the last breadcrumb item in the array

           // and simply check for registry('current_product') or 'current_category',

           // and set the last item's  [`link`] element to either the product's url or the categories URL 

           // example,

          if (is_array($breadcrumbsBlock->_crumbs)) {

              end($breadcrumbsBlock->_crumbs);

              $breadcrumbsBlock->_crumbs[key($breadcrumbsBlock->_crumbs)]['link'] 

                  = Mage::getRegistry('current_product')->getUrl();

               // = Mage::helper('core')->getCurrentUrl();

          }

          $breadcrumbsBlock->assign('crumbs', $breadcrumbsBlock->_crumbs);



        }



        return $this;

  }

Once you set the link part for the last crumb item in the array of crumbs, then it will automatically render the item to include the linked URL.

There is a lot of detail missing with logic and object checking for current_product and category... Essentially, if there exists a registry for current_product, use that... if current_category, use that... otherwise, simply do whatever you want, or nothing at all.

If you don't wish to look up the details of the product/category.. just get the current URL and set the ['link'] element to the current URL.

<?php if($crumbs && is_array($crumbs)): ?>

<div class="breadcrumbs">

  <ul>

    <?php foreach($crumbs as $_crumbName=>$_crumbInfo): ?>

        <li class="<?php echo $_crumbName ?>">

        <?php if($_crumbInfo['link']): ?>

            <a href="<?php echo $_crumbInfo['link'] ?>" title="<?php echo $this->escapeHtml($_crumbInfo['title']) ?>"><?php echo $this->escapeHtml($_crumbInfo['label']) ?></a>

        <?php elseif($_crumbInfo['last']): ?>

        <?php // i have add link code here as below ?>

            <a href="<?php echo $_crumbInfo['link'] ?>" title="<?php echo $this->escapeHtml($_crumbInfo['title']) ?>"><strong><?php echo $this->escapeHtml($_crumbInfo['label']) ?></strong></a>

        <?php else: ?>

            <?php echo $this->escapeHtml($_crumbInfo['label']) ?>

        <?php endif; ?>

        <?php if(!$_crumbInfo['last']): ?>

            <span>/ </span>

        <?php endif; ?>

        </li>

    <?php endforeach; ?>

</ul>

</div>

<?php endif; ?>
