While Mozilla hasn't got around to it yet, Ubuntu (among other free software distributions) includes DuckDuckGo in its Firefox package, which is Ubuntu's default browser.

I expect you know this, but it's worth mentioning here next to the news about Safari.

On this fresh installation of Ubuntu, Firefox is showing DuckDuckGo as the 4th of 8 alternatives to Google.
