Firefox for development.
IE for stuff that won't display in anything else.
It really bugs me when I see pages that require IE anymore. I have a bank that requires IE "for security reasons". Is that an oxymoronic statement? Wife was taking on-line classes from a University and had to use IE to access much of the class material.
As for PR, I don't hardly pay attention to it anymore. Whenever it is updated it gets announced here, and then I will go take a peek. Rarely look other than that.

I use Firefox for browsing and development. IE, Opera and Konqueror for testing.
Opera at least as good Firefox (and way ahead of everything else) in terms of features, but Firefox has lots of extensions, many of which hugely useful. My favourites are: Web Developer, Flashblock (flash not downloaded unless you click to say you want it), Customise Google, Session Saver, Search Status (Google PR, Alexa rank, and some SEO tools), Spellbound (Spell checker) and Disable targets for Downloads (stops sites form opening new windows/tabs when you download things like PDFs).
that said I do not consider myself an SEO guru, but I do care about SEO and it does affect how I design sites.
I will use FF and Safari on occasion for testing.
The new IE with SP2 is much more secure than Firefox and there are many more options and settings that can be controlled with IE.
I don't bother with Opera or Konquerer or Netscape. If people want to cling to Netscape, I'm happy to not have them as customers.
Prior to that, I used Maxthon, also known as IE2.
Prior to that, I used IE.
My only bugbear with FF is it's RAM usage, which often exceeds 100Mg on my system. Not sure if this is a core issue, or an extension issue.
Most of the IE only pages I run across are not due to display issues, but to JS issues. I just love it when a Bank requires use of Active X as a security feature. Gives great confidence in the idea of on-line banking, doesn't it?
