The exploit may not work on your system, and in fact, I personally never installed FF, so I can't even guarantee that it is anything more than a broken demo.  That isn't why I posted this, I did so because this forum was chock full o' IE bashers no more than 4 months ago who extolled the virtues of FF's security. 

Perhaps, in the future, we can cut down on the "The sky is falling, IE Suxxor's" crap and stick to "There's a hole in software X, and here's the patch".

Of course, I'm sure that on Linux, the site would have never caused a problem.  In fact, I'm sure that on Linux, it would have washed my car and mowed my lawn.  Cuz linux is so coool.
