Thanks for the report, this is a new feature in Mozilla Firefox called OCSP Stapling and is designed to be a new way to verify the authenticity of a website certificate, you can read more about it here.

 

I had seen this before and there is an article over on askvg (external site) about it, I will have a chat with out security folks as it doesn't look like its only us thats affected and see if there is something we can do other than advise users to turn it off..

 

I don't like telling users to turn off things to improve security 😛
