SAN FRANCISCO (AP) — Yahoo will supplant Google’s search engine on Firefox’s Web browser in the U.S., signaling Yahoo’s resolve to regain some of the ground that it has lost in the most lucrative part of the Internet’s ad market.
The five-year alliance announced Wednesday will end a decade-old partnership in the U.S. between Google Inc. and the Mozilla Foundation, which oversees the Firefox browser. The tensions between Google and Mozilla had been rising since Google’s introduction of the Chrome browser in 2008 began to undercut Firefox. Google’s current contract with Mozilla expires at the end of this month, opening an opportunity for Yahoo to pounce.
