I am trying to configure Firefox so I can use my CAC card reader with it. My problem is when I try to load a module under Tools>Options>Advanced>Encryption>Security Devices. When I try to load acpkcs201.dll (or any of the other alternate .dll files) I get an error message that says 'Unable to load module'.
When I try to use the DoD Configuration 1.2 add-on from forge.mil, it also is unable to make this configuration.
The CAC reader and software works fine under Chrome and IE. The only problem is the .dll wont load up in Firefox using the add-on or manually.
Does anyone know how to make this module load properly?
