Hello, and thanks for reading. I'm running Firefox v 13.0.1 and Windows 7 64-bit on a home laptop.

I have a CAC card reader, SCM model SCR3340, that I'm trying to get functioning. It uses the ExpressCard interface.

I'm trying to use the OpenSC smart card library.

The instructions seem simple. I go to Tools->Options->Advanced->Encryption, then select Security Devices.

I then select "Load" and then browse to directory c:\Windows\System32. This is the folder where "opensc-pkcs11.dll" is located.

This is the part that is confusing and frustrating to me. I'm able to locate opensc-pkcs11.dll it using the Windows file browser, but it is simply not visible when I try to navigate to it using the file browser in Mozilla.

I don't understand why a file would not be visible to the Mozilla program.

Thanks for any help you're able to offer!

I suspect you had the same issue I did and downloaded the 64-bit version of the OpenSC libraries, but your firefox is 32-bit. You can see the opensc-pkcs11.dll in the System32 folder via windows explorer, but when you browse that directory via firefox to add the module, you are acutally being redirected to the SysWOW64 directory. Try intstalling the 32-bit OpenSC libraries, and adding the appropriate library from the C:\Windows\SysWOW64 directory.
