Firefox Junior is a full screen browser with no toolbar, search bar or omnibox. Instead, the app navigates with two transparent buttons on either side of the screen, located near one’s thumbs that let you go back or open a new page.
The right button, which has a plus sign, opens a page that lets you search for a new page or URL, contains thumbnails of your favorite sites or lets you see other sites you recently visited.
If you swipe to the left, you get another page that looks like the browser’s home page, with thumbnails for separate user accounts and the main Firefox logo.
Mozilla has said this project is still in prototype mode. This means it could quite a while before you and I get to use the app.
