I can not get Firefox to recognize my CAC reader or use my CAC reader to access websites requiring CAC login. IE works fine but I do not want to switch back and forth. Any Help?

I have a CAC reader that Firefox does not recognize. It is installed correctly as have all the necessary certificates and IE can use the CAC reader seamlessly. I do not need the CAC to log-on to my computer, just to log-on to certain websites (mostly military).

You can try to install that CAC reader as a security device in Firefox. You need to browse to the DLL of that card reader.

the dll you want to use is C:\Program Files (x86)\ActivIdentity\ActivClient\acpkcs211.dll

do this and get the Internet Explorer Tab Add-on for firefox and it makes it SO much easier without switching browsers. just right click and pick open in IE tab and ur done, worked 100% for me

Add-on is called IE View

For users that need to change between certificates of their CAC card, I found in Firefox 4.x you have to import the DOD pki files. To do this follow the instructions at the URL below inside Firefox (do all 4). After successfully completing the imports, restart Firefox and when you get to a DOD website like "DISA web-mail" it will ask you to pick the certificate you would like to use. For the email certificate look at the details of each certificate and find the one that has your email address attached to it. This one you much use for all email certificate authentication.

DOD PKI Certificates
