This 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

The focus of development so far has been on building a new user interface that reflects Firefox's design principles, and adds touch screen support and other features that are appropriate for mobile phones and other handheld devices. We plan to do further alpha releases which focus on performance, including projects like TraceMonkey, speculative parsing, and many Fennec and Gecko optimizations. But in the meantime, we feel it is important to make this early release available to continue to grow the community and gather feedback as early as possible in the development process.

To help out, visit the Mozilla mobile page to learn about our public weekly meetings, how to find our community on IRC, and more.

These Release Notes provide a "quick start" for the impatient, some highlights of what's included in this version, download and installation instructions, known issues, and frequently asked questions. Please read these notes and the bug filing instructions before reporting bugs to Bugzilla.

Quick start

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:

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.
