'download.mozilla.org' is listed as ' Connection not secure'. As a result I cannot download FF50. A certificate 'Analyze.ly' is used while verifying download.mozilla .org. Obviously these 2 contradict. I had to add a certificate exception as pictured below but the insecure warning still appears and will not allow downloading.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.
