Hi Alexander, The new offer makes the m-sections inactive which Firefox used for the bundled ICE transport. I can imagine that this causes Firefox ICE stack to think that it needs to negotiate new ICE candidates. But that would be a bug as we should be able to keep using the existing bundled ICE connection. Can you please file a bug on bugzilla.mozilla.org for this?
