Safari used to crash occasionally after about a week of use with lots of windows and tabs open. Since the 10.5.7 update it hasn't had a glitch at all. I've had Firefox crash once in a while, but I don't use it that often to see any pattern.

There may well someday be some malicious code for Macs to worry about, but that day still hasn't arrived despite years of predictions to the contrary.
