Nautilus should be able open web pages as far as I am aware (Read this Page
- it is for RedHat, but may be relevant). If you click web search in the toolbar, it should work. On my syestem, as far as I can see, there is no button. If firefox is not displaying the page correctly, you could try using epiphany which is shipped with the gnome desktop environment (which I assume you are using).
You could install a different browser too. Apart from epiphany, there are many others including Opera and Swiftfox, which is an optimized Firefox build for Linux (and is very, very quick). The page displays fine in this.
Best of Luck
