Firefox is coming to mobile. The innovation, usability, and extensibility that has propelled Firefox to 200 million users is set to do the same for Firefox in a mobile setting.

User experience is the most important aspect of having a compelling mobile product. Every bit of interaction and pixel of presentation counts when typing is laborious and screen sizes are minuscule. Many of the standard interaction models, like menus, always-present chrome, and having a cursor, don’t necessarily make sense on mobile. It’s a wickedly exciting opportunity but there are myriad challenges to getting it right.

One avenue for exploring this opportunity is through Mozilla Labs, which is about pushing the envelope towards better and brighter interaction horizons, as well as incorporating a winder community into the innovation process. This concept video explains one direction we are thinking in, and we’d love to inspire participation in thinking about other directions.

Standard Mockup/Experimental UI Disclaimer
All of the images and videos are only conceptual mockups of an experimental UI for Firefox Mobile, any particular feature may end up looking entirely different, or may not even make it into the final release.
