Beltzner.ca, over a live web presentation has shared an early product plan for Firefox 4 to the Mozilla community. The idea was to get as much feedback as possible and get the whole community involved in their engineering or product development efforts. These were their primary goals for Firefox 4:

• Fast: making Firefox super-duper fast
• Powerful: enabling new open, standard Web technologies (HTML5 and beyond!),
• Empowering: putting users in full control of their browser, data, and Web experience.

Personally it’s a great way to get web communities more involved with other developers as the more ideas thrown out there, worked on and possibly incorporated the better it’s going to be for the end users.
