Why, despite becoming more and more irrelevant each day, do we see such a complete lack of action on the part of Mozilla?
One of Mozilla's greatest assets (far more so than other browser developers) is its user community. What are you doing to ensure their products' continued survival? Personally, I evangelize Thunderbird and SeaMonkey to my friends and coworkers, at least when my advice is solicited or would be otherwise welcome, and at work I make sure our wiki contains instructions on getting Thunderbird to work with the local Exchange (ugh) infrastructure. As far as I know this has converted quite a few users who would otherwise be using the Outlook Web Interface or Outlook in a Windows VM.
