Fennec is the code name of the effort to build a mobile version of Firefox. Fennec is part of the Mozilla effort to enable all mobile phones with a Mozilla application.

The overall goals for Mobile Firefox are:
· provide Mozilla’s standards-based open-source browser engine, optimized for mobile, that can be embedded by device manufacturers and others;
· a full-featured mobile browser including support for XUL-based add-ons, delivering on Firefox’s key principles of ease-of-use, security and accessibility;
· grow the Mozilla community in the mobile space;
· provide tools and documentation to help developers develop, debug and deploy web applications;
· do all of this work in the shared Mozilla source repositories so all platforms, desktop and mobile, benefit each other
