The user demand for a full browsing experience on mobile devices is clear, perhaps driven by the adoption of the iPhone and its Safari browser, which is able to render full web pages instead of mobile or WAP versions. Another option is Opera, which has had a long-standing mobile browsing effort, with popular products including Opera Mini and Opera Mobile.
But will it be too late for Firefox to compete with Safari and Opera? Personally, I think if Mozilla achieves for its mobile browser the same level of extensibility and customization it has in the desktop space, through a vast collection of community-developed add-ons, then Firefox for mobile devices will definitely be a winner. We’ll have to wait and see.
