The Mozilla Internet suite is no more. The marketing gurus have come up with a new name: SeaMonkey.
It doesn’t combine FireFox, Thunderbird, or Sunbird into a new and vastly improved suite. Basically it is Mozilla suite with movable tabs and not much else different. If you like having an all in one solution, and an alternative to IE, SeaMonkey might be something to try.
I’m sticking with FireFox and ThunderBird.
