Technically speaking, Netscape is not dead. Firefox is basically Netscape, although it has come a long way since then and holds its own now.
First coding I ever did.... Ever was for Netscape. And later a little for coding for Phoenix and Firebird, which was what Firefox was originally named (in that order).
They removed the backspace function (go back) I understand why this was done but still prefer it over the new cmd+arrow so installed an extension and got it back. About the rest I wasn't using the Google search next to the address bar (cmd+T and having Google set as the homepage is quicker). But it looks clean and no bugs so far.
