Since the update of Firefox 84.0 I've been unable to use my card reader with a PKCS11 card to login into sites requesting an electronic ID identification. I'm on MacOS 10.15.7 with a Bit4id card reader. The problem is that when I try install the certificate into Firefox in Preferences -> Privacy and Security -> Certificates - Security Devices, Firefox freezes and I must force the closing. At restart, Firefox freezes again and I must restart it using the refresh option, that is I have to cancel all the personalizations and application of add-ons. The dynamic library that Firefox fails to load is libbit4xpki.dylib. The card reader and the card itself are working fine and I can use them with no problem in other browsers. Is anyone having this issue since the update? Any solution??? Thanks everybody! Nick
