Unable to load security device [snap] [libcryptoki]

Hi,

This is on Jammy LTS.

I can not add a security device into Firefox. The smart cards I'm using requires a closed source client software (mPollux DigiSign client) available here: https://dvv.fi/en/card-reader-software . The module the user needs in this case is a PKCS#11 module, for which an open source solution is not available at this time, as open source PKCS#11 solutions do not support the current cards issued in Finland AFAIK (not sure if this is relevant; case may be the snap Firefox fails with *all* security modules at this time, but I don't have other modules to test.).

Loading the module fails with a generic message "Unable to load module" (or the equivalent in the language configured for Firefox). As a general troubleshooting step I reverted Firefox to the non-sandboxed, non-snap version from the ppa ppa:mozillateam/ppa. With the non-snap version, this security module can be added with no problems.

Possibly related (duplicate?): bug #1951646 . I'm not sure about the duplicateness, however it is possible in case the underlying cause is the same.

Steps to reproduce:
1. Have a smart card and a reader requiring to use mPollux DigiSign client (it would be interesting to test other PKCS#11 modules, other smart card modules or any security device in Firefox and see if it works)
2. Try to add a security device in Firefox via Settings -> Security and Privacy -> Security Devices
3. Navigate to the needed .so (in my case: /usr/lib64/libcryptoki.so)

Observed results:
Adding the module fails with a very generic and vague error message.

Expected results:
Adding the module should succeed.
