"What is the Matrix?"
Matrix is an open, lightweight protocol for decentralized, real-time communications.
After a long evaluation period, Mozilla has switched to Matrix from IRC as our preferred open discussion platform. Matrix is a huge improvement in usability, accessibility and safety for the Mozilla community, and we're excited to make this change.
Community Participation at Mozilla
The heart of Mozilla is people. We put people first and do our best to recognize, appreciate and respect the diversity of our global contributors. The Mozilla Project welcomes the participation of everyone who shares our goals and wants to contribute in a healthy and constructive manner within our communities. To that end, as with all Mozilla spaces and events we expect participants in our Matrix forums to support and uphold the Mozilla Community Participation Guidelines as a condition of participation.
New to Matrix, new to Mozilla?
Start with the Riot webapp and create an account. Once you're signed in, clicking these links will let you join the #general:mozilla.org channel for general questions or #introduction:mozilla.org if you're interested in getting involved with the Mozilla development process. There are lots more channels to choose from - there's a list of some of them below - and we'll have more as soon as we get them sorted out.
For more details, scroll down to Connect to Matrix below.
New to Matrix, already part of Mozilla?
Mozilla's Matrix server is configured to use Mozilla IAM, and supports the following accounts:
Already using Matrix?
If you're already using Matrix, you can join the Mozilla conversation by joining the #general:mozilla.org room for general topics and #introduction:mozilla.org if you're interested in getting involved with the Mozilla development process. The whole Mozilla list of rooms isn't settled out and synchronizing across the Matrix ecosystem yet; although many are linked below. In the meantime, those are friendly channels and the people there will be able to help you find your way around.
Using Riot Web or Desktop you can view our room directory using the following steps:
- Click on the Explore button
- Click on the dropdown that says "Matrix rooms (yourserver.com)"
- Click Add a new server
- Type in
mozilla.organd click Add
Now you can view the Mozilla server's room directory and join a room.

Despite our very best efforts, occasionally people do experience behaviors on Matrix that are not inline with our Community Participation Guidelines. If happens to you, please reach out to the room moderator or use our reporting hotline.
Connect to Matrix
Register a username
The quickest way to register a username on Mozilla Matrix is through the web interface.
- Review the CPG and privacy notices and press the Sign In button
- On the sign in page, proceed to Sign in with single sign-on
- Pick your choice of services to authenticate from
- Pick your username!
The Mozilla Matrix server requires Single Sign-On. Clients which currently support Single Sign-On include:
- Riot, the software behind chat.mozilla.org
- this is also available as a desktop client: download here
- Riot Android (also available on F-Droid)
- Riot iOS
- weechat, using the weechat-matrix protocol script. Note the Single Sign-On instructions.
- gomuks a terminal client for Matrix
- Quaternion a Qt5-based client for Windows, Linux, and macOS
While the default parameters in most clients will work just fine, if you're already part of the Mozilla community or want to connect directly to the Mozilla Matrix instance. To do that, you'll need to change the following settings:
These details will be autofilled for you in most clients if you enter your full username (e.g. @susan:mozilla.org rather than susan) into the username field. In general it is preferable to do that rather than trying to remember what the homeserver URL is.
Joining a room
When connected to the Mozilla Matrix server you can join Mozilla rooms and also rooms on other Matrix servers.
There are several different ways to join a room:
- You can follow an external link. (For example, see the links to commonly used rooms lower on this page.)
- You can follow links from inside a discussion on Matrix.
- You can receive an invitation from another Matrix member.
- There are also platform specific methods:
- On https://chat.mozilla.org/ you can click Explore in the upper left and search the known rooms to see information about the rooms and then preview or join the rooms. On the left side you can select or enter another Matrix server and search for non-Mozilla rooms.
- Other platforms: TBA
When you follow a link you you may be given a choice to preview the contents of the room or to join. If the room doesn't allow preview you may be asked if you want to join it without a preview first.
But it is also easy to leave a room. On https://chat.mozilla.org/ find the room name (or icon) in the room list on the left and click the three vertical dots to the left of the name. There are several options on how you want to read the room. plus the option to leave.
Viewing Room Members
Once you have joined a room you can view the room members by clicking on the person icon in the top right. You may notice (depending on your client) that all members appear "offline" or greyed out, this is intentional as "presence" is not enabled for the Mozilla homeserver.
See the field "enable_presence_by_hs_url" in the configuration file https://chat.mozilla.org/config.json
