Descriptions

Mozilla Firefox 4.x through 13.0 and Firefox ESR 10.x before 10.0.6 do not have the same context-menu restrictions for data: URLs as for javascript: URLs, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted URL.

Mozilla Firefox v4.x hasta de v13.0 y Firefox ESR v10.x antes de v10.0.6 no tienen los mismos menús de contexto las restricciones para los datos: direcciones URL como para javascript: URL, que permite a atacantes remotos realizar cross-site scripting (XSS) a través de una URL maliciosa.
