Starting in December, Firefox will use Yahoo as its default search engine in the United States on mobile and desktop. As a part of this five-year deal, Yahoo will also launch a new search experience for Firefox users in the U.S., which should go live at the same time Firefox makes the switch away from Google.
Firefox 34.0 introduced an "enhancement" for the search bar that is normally located the the top left. When I open a new tab (Ctrl+t), it opens to about:startpage. In my case, this is a Ubuntu default including a Google search, that I did not change).
I'm a new user to Ubuntu (to linux in particular). Recently I've changed my FF's homepage from Ubuntu start page(about:startpage) to FF start page(about:home). I can type into the search bar but somehow I can't search (hit Enter or click search button won't do anything): the Google logo is missing. Beside the "Restore previous session" also don't work. What should I do? I'm using Ubuntu 14.04.
