Comment 12 for bug 1967632

unfortunately my summary of @dengert instructions is nor a solution / nor a workaround.

Following those steps I managed to add only one "security device", but it does not work when accessing the website: https://dichiarazioneprecompilatasc.agenziaentrate.gov.it/

The security device I have added uses the module /usr/share/bit4id/x/libbit4xpki.so (FF copies it to /run/user/1000/doc/fb1650f7/libbit4xpki.so)

I didn't succeed in adding: /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so (FF copies it to /run/user/1000/doc/bc62d73/opensc-pkcs11.so but issues "Cannot load module")

I am not in a urgent need of this bug to be fixed, but I'd really like to help in finding the root cause. I am wondering if there is a small shell/python script that can be helpful to isolate the problem avoiding to reproduce the steps with Firefox that hides details.

For example: how can I test from CLI if my smart card reader is working with OpenSC? (keeping out SNAP or Firefox from the test?) I think it can be useful to write down here a simple check.
