Mitchel Baker, chairperson of Mozilla, announced that by 2010 there should be an effective
Firefox in the the mobile market. Here the quotation from the Mozilla dev blog:

“Over the past few weeks, Vladimir Vukicevic has been working on getting TraceMonkey working on the ARM architecture
which is frequently used in mobile and handheld devices. “[M]obile and
handheld platforms are going to quickly become consumers of the full
web, and core performance gains will often yeild much more significant
user-perceptible performance improvements. The result of all this work
will be a richer web experience on mobile and embedded devices, by
allowing those users to take advantage of modern web applications that
do much of their work on the browser instead of server side.” Vlad’s
TraceMonkey work will be available for testing in the next alpha
release of Fennec (the code name for Firefox Mobile) by enabling a configuration setting the same way testers can enable TraceMonkey in Firefox nightly builds. For more information, including a host of technical details, see Vlad’s weblog.”
