Firefox Mobile Alpha Available for Download

is an early developer release of the mobile version of Firefox, for testing purposes only, intended to:
get wider community feedback on our approach to the user experience
engage Mozilla community teams, including localizers, add-on developers, and testers
get feedback from Web developers
This first alpha release is available for the OS2008 (”Maemo”) software platforms that runs on the Nokia N810 Internet Tablets. If you’re viewing this on an N810, install Fennec.

Don’t have an N810? Don’t worry, you can still experiment with Fennec, provide feedback, write add-ons, and get involved by installing a version of Fennec for your desktop PC:

Windows
Mac OS X
Linux

The idea behind releasing the package for PCs is to give people who don’t have a Nokia Internet Tablet the ability to localize, experiment and build add-ons. Note: The desktop version of Fennec is not a supported product.
