I just submitted an entry for the Mozilla Labs Design Challenge Winter ’09. It deals with the new home tab in Firefox 4. The home tab will replace the home button as a persistently open tab that shows a Firefox-hosted start page.
The challenge from Mozilla Labs was to design what would go in this new tab. Whereas most of the other entries focused on complicated metrics and cramming a ton of already existing browser features into the tab, I took a much simpler route in my design.
