It's remarkable that Microsoft Translator in 2016 still doesn't support secure HTTPS websites, for no good reason. Since years ago almost all web sites I use serve HTTPS only, so by now Microsoft Translator is entirely obsolete and almost always useless.
When is this expected to be fixed? For now, you just get the message "Translation of secure pages is not supported. Would you like to continue to the page without translation?"
Re the web's transition to HTTPS, this has been accelearated by post-Snowden eavesdropping awareness, Google's announcement to prioritize HTTPS sites in search results (googlewebmastercentral.blogspot.com/2014/08/https-as-ranking-signal.html) and the
US federal government's endorsement of HTTPS everywhere (https.cio.gov/everything) despite that it has sometimes been seen as anti-encryption.
