This is the second beta release of the mobile version of Firefox, for testing purposes only, intended to:

  • get wider feedback on our approach to the user experience
  • engage Mozilla community teams, including localizers, and testers
  • get feedback from Web developers
  • encourage add-on developers to port existing add-ons and invent new ones for mobile

The initial focus of Fennec development was on building a new user experience that reflects Firefox's design principles, adding touch screen support and other interactions appropriate for mobile phones and other handheld devices, while preserving leading features like the Smart URL Bar ("awesome bar") and support for add-ons.

For beta 2, we have focused on improving the user experience, bug fixes, and performance..

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 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.
