@Mecha_G: I looked into it as I also knew there was something going on, but I didn't knew the details.
It was something along the lines:
Netscape Navigator[ul][*]Mozilla Application Suite (All-internet suite)[ul][*]Firefox/Thunderbird[*]Seamonkey(All-internet suite)[/ul][/ul]
Mozilla dropped quite a bit of Netscape's code, when they changed to gecko as engine. I can't remember, but did Netscape Navigator also contain an E-Mail client? In that case Seamonkey would be the current form of Netscape Navigator-chan
