Ads have officially landed on Firefox’s new tab page

The Firefox browser, lagging its well-heeled rivals, will soon be serving up an array of ads to one and all. Mozilla, the nonprofit group that develops and updates the popular Internet browser, said Thursday that it will begin placing ads where thumbnails of your frequently visited websites would normally be found when you open a new tab. While many of those thumbnails, which Firefox calls “Enhanced Tiles,” will remain as quick links to your favorite sites, some will feature sponsored logos or other promoted images.
