Since i updated to the latest version of firefox i have noticed that everytime i go to my webmail on (servernumber).mail.live.com it connects as a secure HTTPS but then after a minute or so i get an icon to show it's not secure, i inspect the certificates an says websites do not provide certificate, the encryption status shows the type of encryption which looks ok but says "broken encryption" and says mozilla has blocked some parts of the webpage which can be viewed by others etc etc.. it starts off ok which is strange as it's the same server which starts ok then becomes insecure. I'm guessing this is something to do with the latest version of firefox, wondering if any known fix? i'm not after a work around view pages but i want to ensure i am using a secure connection. i do not use kaperspy ( i notice some people had issues with this causing same prob), i do not use any online anti virus which re-routes or scans traffic either, i use comodo DNS if this helps but get no flags from them. It says the website uses weak encryption and is not safe, uses (TLS_ECDHE_RSA_WITH_AES_CBC_SHA, 256 bit keys, TLS 1.2) I have my browser set to wipe cookies + cache on browser exit and login each time manually. Any help appreciated
