I made the switch about 6 months ago. I like Mozilla Firefox better for many things, for one posting images in forum messages is much easier since you can copy the image location on the right click of your mouse button. I am still not quite sure how this is done in IE. Another thing, most popups are designed for IE, since it is far and away more used than FF. So I have yet to see a popup in FF, with IE despite having a popup blocker I get them still, especially on CNN.com and BBC.CO.UK etc. All in all once you get used to it, and it is quick to learn, it is much easier to use than that Microsoft product.
