problem with page redirect Firefox

Hi folks,
am having a problem with firefox, it presents an error with redirect.
I have created a cart page with ecart and when i add this it presents this error, the cart or mini cart is inserted with framework builder and works fine with other browsers, just firefox presents the error.
Some help would be appreciated.
the page can be viewed here:
surfboards.php

All other pages with the cart inserted are working fine which is odd, and no other redirects are used, all pages are created with databridge.

I have also included the actual page and all pages added via framework builder.

thanks in advance

  it presents an error with redirect.  

what is the error?

I am trying to reproduce the problem on your site, but there doesn't seam to be a way to add items to the cart in order to test the redirect. I'll need more details.

u just have to view the page in firefox and u will see the error :)

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
This problem can sometimes be caused by disabling or refusing to accept
cookies.

ie doesn't even display the page it redirects to the index page, the page con only be viewed with Chrome
surfboards.php

in the inc/cart.php page, change the following code:

<?php

// WA eCart Redirect

if ($eCart->redirStr != "../cart.php")     {

  header("Location: ".$eCart->redirStr);

}

?>

to:

<?php

// WA eCart Redirect

if ($eCart->redirStr != "")     {

  header("Location: ".$eCart->redirStr);

}

?>

thanks working :)
