Personally, I build in IE and use SlimBrowser to get me around the web (also OS, but
much slicker than FireFox, and is not so finnicky).
Besides, I can skin it with whatever look I am in the mood for! 
The
real reason so many of you are "FireFox Fanatics" is because it was the first
FREE alternative to IE way-back-when, and
not because it was superior in any way whatsoever (which just goes to show you how simple marketing works wonders)!
As a matter of fact, many of the issues FF faces yet today (and provides so much constranation here in VT) have not been resolved effectively to satisfy most professionals on the net, let alone be an obvious
constant nuisance to casual users......like the mention of MS updates and
many downloads not processing properly --
almost forces one to get a third utility such as IDM just to take care of business! * One of the first and still the best alternatives to IE which not only is more robust and multi-functional but is also the same foundation many other utilities are based on by sharing/*******ting code is the browser in ACT.....but, this all-in-one tool (admin, email, contact manager, browser, HTML doc preparer, etc.) seems too difficult for the majority of people to learn how to use.
