but of course,when you get down to it, the only reason IE got so bad, was because that it was the main brower, the deafault of them. any illiterite computer user wouldnt even realize that there were more browsers to choose from. So , by common sense, a hacker would choose the most widley know browser to hack, because,well, theres more people that are using it. So if firefox begins to dominate the browsers, there will be nothing left of firefox's sparkling sense of virus and pop-up proection. The same story could be compared with a anti-virus software.
