Translates the page well. The one problem is using it confuses YouTube so that videos get the wrong titles, some videos suffer from missing or concatenated channel titles, and some comments are concatenated or on the wrong video. This only occurs after turning on the translator, even for a brief second. If it is on for longer, video titles and channel names mysteriously vanish, then channel titles reappear concatenated and video titles reappear on the wrong videos. Leaving YouTube on for longer only makes things worse.
