The only things I use in Mozilla 1.0.1 (which I switched to because Netscape Navigator was overloaded with non-essential extras) is the browser called Mozilla with incorporates the Mail & Newsgroups (which allows for the set-up of multiple mail servers, all in the same place, as noted earlier) and includes an address book (handy for "collected" email addresses, much like Gmail).
So I'm surprized to hear that Firefox 7 wouldn't include such. Ah well ....
