"The page isn't redirecting properly" error in Firefox for non-admin users

Firstly, thanks for this module. I've been wanting something like this for a long time now.

I'm not a very advanced programmer but I've found that the following part of the simple_review.module file causes the error:

---------------------------------------------------------------------------------------------------------------------------
// Check whether the user has already reviewed this node (except admins)
if (simple_review_already_reviewed($form['nid']['#value']) && !*user_access('administer comments')) {
drupal_goto("node/{$form['nid']['#value']}");
}
---------------------------------------------------------------------------------------------------------------------------

I've found two temporary solutions to this.
a) Delete the browsers cookies (however visitors will not know to do this).
b) Comment out this block of code. This fixes the problem but allows members to vote an unlimited number of times.

Good luck,
Jake.
