@natty @ezio but Netscape 6-7 wasn't all that different from Firefox. Just without extensions. I mean yeah, you had a mail client - but it was basically Thunderbird, and you had Composer, but it sucked. ^^
I did actually start from Mozilla, but since I only used the browser part at the time, I honestly didn't notice any difference when switching to Firefox. Well ok, it had different toolbar icons, and got rid of the M-turning-into-dinosaur throbber, but that was it basically. Granted, I was a child at the time. Still, until I specifically researched it years later (which included using SeaMonkey for a while), I didn't even know about most of the differences.
Unless you mean Netscape 4?
