Mozilla will start showing third party sponsored content through the Firefox browser. Ads will be shown on the "Directory Tiles," items on a page when a user opens a new, empty tab. Mozilla calls the new program Directory Tiles. Currently, if a new Firefox user opens a new Tab page, it consists of nine boxes (tiles), empty to new users. The tiles populate over time with the most frequent and recent websites a user visits.

Mozilla says that Directory Tiles will instead suggest pre-packaged content for first-time users. Some of these tile placements will be from the Mozilla ecosystem, some will be popular websites in a given geographic location, and some will be sponsored content from Mozilla's partners. Mozilla said the sponsored tiles would be clearly labeled as such.



Mozilla says that the new feature will take place on the desktop browser, before spreading onto Firefox for Android and devices running Firefox OS.
