Hi, on my iPhone, I can readily save or print the PDF files displayed in Safari. In Firefox with the latest version, the PDF files display as well as in Safari, but I cannot print them properly, nor save them on the iPhone or in a cloud. They do appear to save properly, but when I try to display them in Acrobat or in Word (Microsoft Office 365), the document won’t even display in the application. The same problem occurs with files downloaded from various web sites. Can you help? Thanks.

Tengo una instalación previa del módulo de seguridad PCKS#11 en la que aparece la ruta como: "null". El sistema no me deja ni borrar el módulo ni modificar la ruta ni instalar un nuevo módulo. Qué puedo hacer?
