A quick tip if using a smartcard reader (for things like CAC) with Firefox – some web sites may not work right if you cannot select the proper certificate. Some sites want the signature certificate and others want the email certificate. Internet Explorer offers you a choice – Firefox may not, unless you do THIS:
- Open Preferences.
- Advanced menu, Certificates – “When a web site requires a certificate”, select the button “Ask me every time”.
This will then force all sites to present you with a choice of certs to use from the card. A little clunky, but it works well.
