Unfortunately, now that it's "on the radar", we will see the hackers start to expose the flaws inherit in every piece of software. We've already seen this happening in older versions of FF.
Still, this is good news for FireFox, and for OSS in general.
Yes. That's why Apache, with three times the installed base of Microsoft's IIS, it exploited so much more often....
/sarcasm
I'd be interested in any reliable studies that indicate that such a thing is true. Until then, however, please stop repeating this myth.
The key will be how effectively mozilla keeps Firefox patched -- especially patching flaws before they become public.
But, no matter how you cut it, IE's real problem is Active X. Active X is a public exploit designed into the browser. Keeping safe while using IE requires careful adjustment of the chair-keyboard interface.
