Let's say I have an user certificate (PKCS#12) at http://example.com/example.p12
When I point Firefox to that URL, it does nothing. It doesn't install the certificate, it doesn't show a dialog box, it doesn't show an error, it doesn't even reset the former page.
Firebug tells me that the certificate was received with Content-Type: application/x-x509-user-cert, which seems to be the correct MIME type.
What am I doing wrong? How could I make firefox import the certificate?
Note: If I import the certificate manually (downloading it then importing it from the Preferences>Advanced>Encryption>View Certificates>Your Certificates>Import...) it works perfectly.
