This problem is an Ubuntu/snap packaging issue. FF and Thunderbird both allow the loading of PKCS11 modules as do other programs. But the snap has not packaged these.
Access to smartcards is usually handled by PC/SC i.e. the pcscd daemon. It provides locking access to the smartcards from multiple running applications. So this is another issue for snap, how to provide access to this system daemon. Snap does provide the ability to load the p11-kit but then p11-kit tries to load other PKCS11 modules which may need to load additional libraries. /usr/lib/x86_64-linux-gnu/pkcs11/* and run "p11-kit list- modules". p11-kit has a client/remote capability that I have never looked at. It might be possible to use this from snap to a "remote" server running on the the local host. Are there FF extensions that may similar problems? Until Ubuntu can packaged up other pkcs11 modules and handle pcscd, the way to: "test from CLI if my smart card reader is working" is to use the debian firefox-esr which does not have any problems. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1967632 Title: [snap] apparmor denied when trying to load pkcs11 module for smart card authentication Status in firefox package in Ubuntu: Triaged Bug description: I use a smart card to access government sites.
