After registering for an account by providing a valid email address and username/password you can log in to the
add-on to join chat rooms. Both public chat rooms and private chat rooms are available, but private chat rooms are only accessible to users which have added each other as friends. There are several customization features such as picking a unique username color and a custom notification sound that will play in private chat rooms only when the Firefox
browser is not the focused window. The chat windows will appear in the lower right hand corner of the page and both the visibility and opacity of the extension can be toggled through the add-on panel.
