Mozilla developers have been working on an iPad browser called Junior.

Optimized for tablets, the new browser is simple and does not have a URL bar or tabs. Looking more like an app rather than a slimmed down desktop browser, Junior has two buttons on the left and right side of the screen that are operated by the user's thumbs when the iPad is held in portrait mode - at least according to a video posted online by Mozilla. The left button is a back button thatallows users to visit the previous page. The search bar can also be used as an URL bar, the developers said.

Both buttons can be pulled into the screen to reveal four sub-buttons. Behind the back button users can find a reload and a forward button; behind the plus buttons users find a share and a print option.

Junior has also multi-user accounts built in to make it easier for families who use the same device to switch between accounts.
