Mozilla is working on its own OS and hardware abroad, but its also trying to make its existing software more relevant for users… and a little more profitable. When a user first installs Firefox, opening a new tab will bring up a mostly blank page, with only Firefoxs own welcome message as a frequently or recently visited site. As they break in the browser, the tiles will fill up, but now Mozilla plans to kickstart the process with something it calls Directory Tiles. Directory Tiles are described as a set of pre-packaged selections with a limited level of personalization.
