I seem to have fixed the problem by removing
Code:
<?php echo $product['productsImage']; ?>
from the following code block
Code:
<td class="cartProductDisplay">
<a href="<?php echo $product['linkProductsName']; ?>"><span id="cartImage" class="back"><?php echo $product['productsImage']; ?></span><span id="cartProdTitle"><?php echo $product['productsName'] . '<span class="alert
bold">' . $product['flagStockCheck'] . '</span>'; ?></span></a>
<br class="clearBoth" />
in the tpl_shopping_cart_default.php file.
I do not have product images for tested product and suspect that the problem is therefore being caused by the title tag for the image being mishandled in some way by Firefox in the absence of an image, thereby printing on the screen the contents of the that tag next to the product title, because this would be shown under the title tag in the source code (which it is), not as a duplicate listing title.
If I could locate the title tag for <?php echo $product['productsImage']; ?> I would remove the tag and see what happens, but I have been unable to locate this detail.
The only problem now, of course, is that the modification to the .php file is going to affect all my product listings... unless I can locate that darned title tag...
