Mozilla have just passed a new set of guidelines, the Mozilla Community Participation Guidelines.

https://www.mozilla.org/about/policies/participation.html

"The Mozilla Project welcomes and encourages participation by everyone. It doesn't matter how you identify yourself or how others perceive you: we welcome you. We welcome contributions from everyone as long as they interact constructively with our community, including, but not limited to people of varied age, culture, ethnicity, gender, gender-identity, language, race, sexual orientation, geographical location and religious views."
