Currently WebRTC and Hello is for two users, no "group" connections are possible. That may change in the future though, as WebRTC is still in development.

I am guessing that one of the users is me but I don't have any indication that I have a session going. Is the conversation opened when I start a new session? if so I get no questions about using the camera or the mic. If I join an existing session I get on but when I try to get on from another computer I get the message that 2 people are already in session. I am using 2 computers in the same house. Thanks for any help,

Have you read the support documentation for Hello? See this KB search.

Specifically, these support articles: https://support.mozilla.org/en-US/kb/firefox-hello-video-and-voice-conversations-online https://support.mozilla.org/en-US/kb/join-conversation-firefox-hello

When you generate the link, a small conversation window should open at the bottom-right. That will automatically join you to the room.

You can then share that link with someone, or another computer, and they should be able to join.

Note that for links you generate, if you click the link and have it in a tab, that will currently stop anyone else joining.

We're working on improving this in a future release.
