Gecko:Getting Started

The first step is to [download and build](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions) Mozilla or Firefox.

See the information on hacking Mozilla for how to work with the Mozilla project and coding conventions.

If you get stuck at any point, send a question to a Mozilla newsgroup, or get onto IRC at irc.mozilla.org, channel #developers. Do not give up, there are people who want to help you.
