Internet Explorer is much more powerful that Firefox.
For example, when Firefox crashes I just have to restart it, and keep browsing.
Firefox even remembers the tabs I had open, thanks to the sessionsaver extension. However, when IE crashes it takes down the whole operating system, the fridge, the toaster, and any pacemakers that may happen to be nearby. Also, the neighbour's cat starts behaving strangely. Now that is real power.

Quite amazing. I had that with W97/Office Pro 97 both supplied as unlicensed by a former business partner who so thoughtfully "just forgot" to tell me the correct licensing position. For reasons which I found incomprehensible, ever since then standard light bulbs always packed up within a few weeks.

So now I definitely will not be going back to IE any version. :D
