How is Thunderbird different from Netscape?
Thunderbird uses the same “underlying code” as Netscape so the look and feel of Thunderbird is very similar to that of Netscape Mail. But one enhancement is that Thunderbird is faster than Netscape Mail. The reason for this is that while Netscape needed to “check-back with the server” for some processing Thunderbird does that processing locally, meaning on your computer.
