I have been getting different SSL errors when navigating to different websites. Some I have visited before, some new. Here are samples:

Secure Connection Failed

An error occurred during a connection to <website>. Peer could not decode an SSL handshake message.

Error code: SSL_ERROR_DECODE_ERROR_ALERT 

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

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Boot the computer in Windows Safe Mode with network support to see if that has effect.
