FireFox can also have bugs? Could it be that FireFox developers make mistakes too?
Ever since FireFox started to gain momentum you constantly hear "FireFox is much more secure than IE". These opinions are usually shared by folks that have not grasped the concept of software development and popularity. Anything written by any human is apt to have bugs. Do you really think that FireFox engineers are brighter than any other engineer out there? Do you think that with the cash Microsoft has on hand that they can't afford quality engineers? The fact is that bugs are a fact of life, humans make mistakes and a FireFox engineer is no different than any one else. In fact, according to an article in Internet Week, there are a pair of critical issues in FireFox that required you to shut off Javascript to be safe, pretty nasty stuff. Just goes to show you that with popularity, awareness is increased and bugs are found.
