"They were also in files associated with said apps." HUH? That simply makes no sense. WHAT files? WHERE did such files come from? Any browser 'can' have security holes, but IE is famous for them....Firefox is not 'targeted' particularly. It IS better protected against pop-ups & spam.

Either Opera OR Firefox will allow you to work offline....either one will allow you to save your history file in whatever level you specify. I have used ONLY Opera & Firefox for 5 years now..(ever since Netscape went AOL) I open IE maybe twice a year.

"If you have a website having old browsers is essential - unless you want to dis-enfranchise surfers (in your ignorance)."

ummmmm...I sorta see what you are getting at, but it's rather like saying you 'need' an old car with no modern technology, just in case your great-aunt Matilda needs to drive it once a year.
