Mozilla today rolled out Firefox 34. While most browser updates these days aren’t all that exciting, this one includes a couple of interesting new features. What most users in North America will notice right off the bat, however, is that this is the first version of Firefox with Yahoo as its default search experience.
It’s easy enough to change the default search engine in Firefox, and I would guess that most current users will quickly switch back to Google. The Yahoo Search experience, which the company specifically tweaked for Firefox users, is perfectly all right for most searches. But at the end of the day, it feels like it doesn’t have some of Google’s smarts, especially when it comes to queries that would usually trigger Google’s Knowledge Graph.
