Cannot see embedded youtube videos anymore on Firefox

This just started yesterday and all I'm seeing is the following message:

Secure Connection Failed

An error occurred during a connection to www.youtube.com. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. (Error code: sec_error_reused_issuer_and_serial)

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

however youtube itself works in FF and I can see embedded videos in safari.
