This is a quick and dirty addon to add a webrtc website as an app. As webrtc advances so rapidly there is s a chance this addon will be obsolete. Webrtc is a new video and audio conferencing tool that is browser to browser communication, no need to download specific software for just conferencing. There are many different webrtc instances and because of the technology it is really a person 2 person communication, using the server to only signal who wants to talk to who, the actual transfer of the audio and video is directly between the participants.
If you would like to try this addon please download one of the following either Chrome/Chromium 25 or higher or Firefox 21 or higher. Then test it by visiting a known webrtc instance (i.e. live.mayfirst.org) create a room, you should be asked to share your camera and microphone (firefox will let you choose one or the other, whereas chrome/chromium asks for both in one question).
If the test is successful then proceed with copying the webrtc instance you would like to use and place it in the config window and save. Now when you open the app it will load the webrtc instance for you to use.
