Comment 50 for bug 1967632

I don't know if this could help someone but firefox from mozilla repositories didn't worked for me neither (Kubuntu 22.10)
If I remember correctly I noticed that pcs package is not installed by default, in addition the service pcsd didn't run by default, in this context firefox can't add the module.

So after install pcsd and after active the service with:
-sudo apt install pcsd
-sudo service pcscd start
-sudo systemctl enable pcscd (this is to keep the service running after a reboot)

I could active the module correctly. Sadly when I did this I had replaced firefox snap by firefox from mozilla repositories so I'm not sure if this could make work the module installation on snap.
