Yep, although parts of the article are a little bit confusing/misleading: it's default in the US only, and for the time being it's offline (no additional telemetry). It might be rolled out on a larger scale, possibly with more telemetry, but in that case requiring user opt-in. Still unclear if/when this will happen.
So I thought it worthwhile to highlight the actually relevant part of the article: how to disable FF Suggest :)
