[Software] Problem adding module in Privacy and Security on Firefox

[checco]

I have a problem logging in with the CIE (electronic identity card) via the bit4id minilector air v3 CIE reader using Firefox v147.0 on Kubuntu 25.10 (wayland). With Google Chrome everything works fine (it works perfectly), but in Firefox I need to add a module under Privacy and Security and then under Security Devices, as described on this site: https://idserver.servizicie.interno....ux_firefox.jsp
I followed the instructions step by step and entered the module name correctly, but when I specified the "libcie-pkcs11.so" file in the "/usr/local/lib/" directory and then confirmed with OK, it says "unable to add module" and changes the directory I specified to "/run/user/1000/doc/9bc2c4b1," where the same file, "libcie-pkcs11.so," is also located.
Can you help me?

P.S.: Firefox is installed by default, no snap or flatpak and I use chrome as default

I've attached a screenshot of the problem.

Firefox is a Snap by default, unless you manually installed it. The use of /run/user points to you using the Snap version.
If you are NOT using the snap, this might be a Firefox/CIE issue more than an Ubuntu one.

You *might* be able to allow smart reader access in the snap

The instructions may need to be modified to suit your setup, but possibly just enabling a connection to pcscd might be all you need to do to allow you to select the file properly, as shown in the CIE instructions.
