Welcome to Mozilla’s standards participation page.
Web standards are the technologies web developers use to build websites, are supported by Firefox and other browsers, and are developed in open standards groups. This page serves as a directory of standards organizations and working groups that Mozilla contributes to.
- For more on the topic of What are web standards?, see MDN: The web and web standards
- For a technology summary see MDN: Overview of modern web technologies
- For Mozilla’s positions on particular specifications, see: Mozilla Standards Positions
- Current discussions of Mozilla standards positions: https://github.com/mozilla/standards-positions/issues
The lists below are organized alphabetically by standards body and working group (if any), with Mozilla participants and specifications they edit/author/contribute to.
If you’re a Mozillian actively & directly participating in a standards body (working group email list, IRC, wiki, and/or f2f meetings), please add yourself to the specific standards body / working group if any), linking to your wiki User: page. If you’re working in multiple working groups or standards organizations, add yourself to each.
Web Standards Coordination
General Participation Guidelines
If you'd like to participate in some of these groups, or at least watch, learn, get up to speed, you can almost always do so by lurking on the public IRC channels and mailing lists that the groups use. Many (most?) standards mailing lists can often be overwhelming in quantity, depth so start with IRC as that's often lighter-weight and easier to watch for quick bits of info/knowledge.
- Most W3C participation uses GitHub.
- Create an account, if you don't already.
- Substantive contributions to W3C specifications are checked by a bot that verifies that you have made the appropriate IPR contributions. Mozilla employees (both corporation and foundation) can request an invitation to the mozilla-standards group on GitHub on the `#standards` slack channel. Membership in this group signals to the W3C bot that Mozilla's IPR commitments cover your contributions by virtue of your employment.
