FireFox has an IRC client, chatzilla, not to mention x-chat or whatever the other client that is installed.
Email is also included as well as liferaa the feed reader.
There are plenty of proxy add-ons available per mozilla as well as google and already included.
FF can mask itself as well. There is an add on or changing the about:config file in FF.
Kubuntu is Ubunutu with the KDE desktop manager. BT= is Ubuntu with KDE and a whole bunch more. Which is pretty much pointless.
There are plenty of threads why kde4 was not included so do have a look around.
SpoonWEP/WPA is no longer supported and we know the author. Matter of fact like He has a newer tool there is a thread on it, again I encourage you to browse around.
