That was fast. It was just two weeks ago that Mozilla announced a deal making Yahoo the default search engine in Firefox, and now you can download an updated version of the desktop web browser (Firefox 34) that uses Yahoo as its out-of-the-box search option in North America. The app thankfully won't override your existing choice if you're a veteran user, but it will ask once if you'd like to switch. Android users aren't seeing a similar change in search providers, although it's likely just a matter of time.
