I can't talk about that specifically but something has changed at DuckDuckGo in the last 24 hours or so. That is DuckDuckGo has stopped working properly on browsers where JavaScript has been blocked (but it's still OK if JS is running).
Moreover, browsers such as PaleMoon without WebRTC seem to be more affected than others. What happens is that the homepage loads but the queries are no longer answered (properly submitted).
I'd add that I've had to switch to Startpage.com in the interim until I figured out what has happened (it works on all browsers without JS just as DuckDuckGo did a day or so ago).
