Prevent Duplicate Form Submissions with jQuery

Some shopping cart forms will allow buyers to click the buy/submit button more than once, resulting in multiple charges to the same person, and irritation. There is a simple way to prevent duplicate form submissions using jQuery. This script prevents a form from being submitted twice, except when using Firefox 3.x, which will submit the form no more than twice if the visitor is clicking the submit/buy button repeatedly.
