Alipay has announced that it will not permit the Firefox users to access its secure Web page and process the payment after this August 15. The main reason is that information layout on the Alipay site can’t be authenticated via Firefox browser, and the Opera browser as well. It is therefore, the Firefox users need to download an add-on, i.e. IE tab in order to continue using the Alipay system, as shown on this page (in Mandarin).
