The agreement, called “the most significant partnership for Yahoo in five years,” will introduce an enhanced search experience featuring a “clean, modern and immersive design” for U.S. Firefox users starting next month. The partnership will also open up the door to explore other product integrations between the Internet company and the Internet browser. “We’re so proud that \[Mozilla has\] chosen us as their long-term partner in search, and I can’t wait to see what innovations we build together,” said Yahoo CEO Marissa Mayer in the statement. “At Yahoo, we believe deeply in search – it’s an area of investment, opportunity and growth for us.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3596218/yahoo-mozilla-partnership/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3596218/yahoo-mozilla-partnership/"},"headline":"Yahoo Will Be Firefox's Default Search Engine Until 2019","datePublished":"2014-11-19T22:52:16.000Z","dateModified":"2026-04-13T08:03:44.524Z","description":"\"Most significant partnership for Yahoo in five years\"","url":"https://time.com/3596218/yahoo-mozilla-partnership/","keywords":["Companies","Tech","Web"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltcdc5288ca6e165b9/698769c606f2c1ec6a332583/103010494.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Jack Linshi","jobTitle":null,"url":"https://time.com/author/jack-linshi/"}],"articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltcdc5288ca6e165b9/698769c606f2c1ec6a332583/103010494.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"A screen displays the logo of the open-s","caption":"A screen displays the logo of the open-s","creditText":"Leon Neal—AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/companies/","name":"Companies"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3596218/yahoo-mozilla-partnership/","name":"Yahoo Will Be Firefox's Default Search Engine Until 2019"}}]}] ```
