In order to digitally sign legal documents on a governative web portal, I've been obligated to install and use this Spanish governative tool on my win pc: https://autofirma.net/ My concern is about the fact that the Autofirma tool uses its own dialog to acquire Firefox Primary Password. So my question addressed to Firefox developers: since Autofirma acquire the Primary Password, can it also access my stored passwords? Or the use of Primary Password by Autofirma is limited to invoke Firefox?
