Mozilla Corporation has said it plans to get serious about developing a mobile browser. As devices like the iPhone have shown, people want a full browsing experience on mobile devices. Mozilla hired two new developers to help with the objective, and will continue developing Mozilla2 with mobiles as a device category. Mozilla2 is due out around 2009. PC World has a more in-depth report.
Personally I would love to have Firefox on my PDA. Though Mozilla is likely to encounter competition from Apple and Microsoft, who bundle their own mobile browsers on devices using their operating systems, and Opera ASA, which has been fine-tuning their mobile browser version for years, a mobile version of Firefox will probably catch on about as well as the desktop version has. I look forward to a day in my rosy, perfect-world future when all devices bundle Mobile Firefox, and Internet Explorer has been extinct for years, but that, at least the latter part, is highly unlikely. I do think, though, that a mobile Firefox will get users, especially as mobile Internet browsing becomes more mainstream.
