Hi, I have a 115.6.1 (64-bit) version of Mozilla Thunderbird, and yet the device manager does not accept 64bit PKCS11 drivers (from C:\Windows\SysWOW64) for smart cards (tried several smart cards). It only accepts 32bit drivers. I have a smart card which does not have a 32bit PKCS11 driver.

Does anyone know why a 64bit version of thunderbird does not support 64bit PKCS11 drivers? Would any of the developers be able to address this please?

Thank you.

Sorry for the confusion, Windows are a bit ati-intuitive compared to MacOS or Ubuntu. System32 is a 64-bit repository and SysWOW64 is a 32bit repository. The 64-bit versions of Firefox and Thunderbird correctly support the PKCS#11 drivers from System32 (the 64-bit repository).

No, they are quite unrelated. There is one regarding 32bit PKCS#11 drivers, but that is 7 years ago and does not relate to unsupported 64bit PKCS#11 drivers. All my 32bit PKCS#11 drivers can be loaded, but none of the 64bit PKCS#11 drivers. And I have a problem that one of my crypto smart cards does not even have a 32bit PKCS#11 driver (it is 2024).
