I am trying to use a CAC/PIV reader to authenticate and access a Microsoft OWA site. This process works fine on both Chrome and Safari but I'd prefer to use Firefox. So far, I've installed and loaded the Keychain-PKCS11 library and restarted the browser. When I start the browser--before trying to go to any page--I get this error: "Please authenticate to the token “[TOKEN NAME REDACTED]”. How to do so depends on the token (for example, using a fingerprint reader or entering a code with a keypad)." When I go to the log-in page and select the "login with CAC" option, Firefox returns a certificate-not-found error.
