I suppose this might be the first direct work by Mozilla on Linux kernel code, but I've always seen Mozilla as a "Linux-related" project. Maybe because I've been using both of them together for many years ;) And on another tangent Mozilla is part of OIN, whose goal is to promote Linux. So not sure I follow what you mean by "not plugged in".
But I could be easily wrong though. If so, maybe this is a good opportunity to work closer together.
