recently they been showing off new user interface mockups of the next major release - Firefox 4. Staying true to its long-standing focus on openness, Mozilla has launched the Firefox 4 Design Challenge this is a series of events meant to encourage innovation and experimentation in user interface design. The first challenge asks you to concentrate on ideas for switching Firefox’s Home button to a Home tab that will facilitate start pages in the browser similar to MyYahoo and iGoogle start pages. They have supplied the following mockup of how the browser might keep the new start page concept available up top via the Home icon at left:
If you want to participate in the Design Challenge you have to submit a short video explaining your concept and presenting a mockup that clearly shows how a new start page might work. Wireframes and polished comps are also welcome. Mozilla has a submission form available here and example templates are available here. How often can you use your time off to influence how millions of users will interact with the web.
