Question

youtube video pops up SSL certificate dialogue

Firefox 18.01 is configured with many root certs and smartcard support.

When I view the youtube video at http://www.youtube.com/watch?v=qkM6RJf15cg , I get a popup:

[JavaScript Application] This website may rquire a SSL certificate. Please insert your smartcard or Common Access Card and chose OK to try again. OK/Cancel

All the other videos I've tried don't create that popup.
