Mozilla-based browsers contain a cross-domain vulnerability, which may allow an attacker to access data in other sites.
Mozilla uses a same origin security model to maintain separation between browser frames from different sources. This model is designed to prevent code in one domain from accessing data in a different domain. From the same origin policy:
Mozilla considers two pages to have the same origin if the protocol, port (if given), and host are the same for both pages.
By convincing a victim to view an HTML document (web page), an attacker could modify data in another domain. For example, web page script in one domain could set a cookie for a web page in another domain.
