Description

[ithompson4]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170518000419

Steps to reproduce:

1. I restarted my PC on 28th January late afternoon.
2. I attempted to rejoin a Skype conversation page URL https://join.skype.com to
    which I had been successfully connecting since late January,


Actual results:

1. I was unable to connect to the web page 
2. I received instead the following error message every time I tried to reconnect.  
    "Secure Connection Failed

     An error occurred during a connection to join.skype.com. Invalid OCSP signing
     certificate in OCSP response. Error code:
     SEC_ERROR_OCSP_INVALID_SIGNING_CERT

     The page you are trying to view cannot be shown because the authenticity of

Expected results:

I should have been able to successfully connect to this page and Skype conversation using Firefox as I had been from late January 2017 until late afternoon of the 28th May 2017 when this  ridiculous error started appearing.

COMMENT: There needs to be a manual override facility for users to be able to force a connection for occasions when Firefox makes an obvious and serious mistake (in this case Firefox cut me off from my work group). In this case I had to drop Firefox and use Internet Explorer to successfully rejoin my Skype group conversation. Internet Explorer connected without difficulty and without any nonsense "Secure Connection" error messages. 

Environment: Firefox version 53.0.3 (32-bit)
