"As early as 2000, when Firefox was but a teething babe at the Mozilla programming lab, K-Otic.com had found three exploits for early Mozilla programs, bugs that would apply equally to Firefox, Purita said.
The tally grew to 15 exploits in 2001. It bulged to 27 exploits in 2002, and in 2003, reached 30 known exploits. Last year, the number of exploits nearly doubled."
30 in one year on relatively new code vs. hundreds per year on IE that has been around for a decade or more?
Yes, I understand there are more people hacking away at IE, but come one now, they've been doing it for YEARS and they're still finding things! I'll still stick with Firefox.
