Mozilla on Mobile?

• "Firefox on your phone" - a product
• Linux, Windows Mobile, looking at Symbian

Where are we today?

• Nokia N810 - "Powered by Mozilla"

• ...and helping Mobile
• Mobile focus will now help desktop

Examples

• Startup time improvements
• Better distribution (xulrunner as base)
• Mobile integration back to desktop?

In Conclusion
