I couldn't even manage the other day to get Google Translate to translate a YouTube page so I could read comments mostly written in cyrillic to a Russian video about the protests over there.

Perhaps I was doing something wrong (I don't think so), perhaps it's because I use Firefox and this was a gentle nudge to get me to try in Chrome, or perhaps it's just another one of Google's infuriating and perplexing 'quirks'.
