Install dod-configuration-1.0.2.xpi into firefox by downloading it to a local directory and then doing “File|Open”. You have to get this from https://software.forge.mil which you can only get to with your CAC. Yes, I know. This makes a lot of sense. I got it from a co-worker.

Plugin your CAC card reader and insert your CAC. The green light should come on. Next, you will to set up the CAC in Firefox.

Open Firefox, goto Edit | Preferences | Advanced | Security Devices.

Click Load.

Enter the following:
Module Name : CAC Module
Module filename : /usr/lib/pkcs11/libcoolkeypk11.so

The CAC should appear in your list of security devices now. Click “Log in” to test it. It should look something like this:

Click “Log In” and enter your pin to test it.

Try to bring up https://software.forge.mil. Firefox will complain about the cert so just add an exception for it.

You should be all good. Let me know how this works out.

NOTE: I’m using Firefox 3.5
