Another Serious MSIE Hole

pjrc writes "Infoworld is reporting another new security hole that allows links to executable files to appear to be any other type of file, such as text or pdf. When combined with a previously reported spoofing bug, that Microsoft still hasn't fixed, Infoworld claims the result could be 'devastating'"

    I know this isn't an ask slashdot topic, but does anyone have any tips for how to get people to switch from IE to Mozilla/Firebird? I just don't understand why I can't get people to change, and Lord knows I've tried.

    I don't understand it, I really don't. I've seen people complain about viruses, bugs, pop-ups, and ads, and yet when I suggest that they go with Mozilla, they don't want to switch. Why? "Because IE's there." Or "because Mozilla takes too long to load." "Using quickstart isn't worth it because IE starts when the system does, so why run two browsers at the same time?" But yet they'll complain about a 5 second load time for Mozilla, when they'll spend more time than that closing pop-ups and resetting their homepage from where someplace changed it. I've even come across the situations where people won't switch because Mozilla had a different print screen (even though I used an IE skin so the rest looked the same), and one didn't want to use it because when you opened a "new" window, you didn't get the old window in it. Even after I showed them the clone window extension (which is pretty close to the same functionality), he didn't switch. It's just frustrating.

    It's sad, Microsoft has people so brainwashed that they'll complain until they're blue in the face that IE sucks, and yet they won't switch unless you put a gun to their head. So does anyone have any suggestions for just how to make them switch? (without actually putting a gun to their head)
