Win98SE? You're kidding, right? I literally hated that system and thought it the worst MS ever offered. Crashed more times than Sonny Liston got hit.
I use Firefox also and think it's great.:)
I know, I know, I'm a computer consultant and work with XP and just about all the other MS workstation and server OS's.
I think I've said it before on FR, it's like my carpenter brother not having a banister on his dangerous staircase for years before he got around to installing one.
Plus, I've got years of crap loaded on my main workstation and dread upgrading it all.
