I think one of the main reasons IE still has market dominance is because the vast majority of PC users don't know that there is any other option. :shrug:
I've been using FF for years, though I went through a period of using Avant, which is built on top of an IE base, but was better imho, if not only for the way it displayed bookmarks/favourites, which was across the page in columns, rather than one column. And that column of favourites is not scrollable in IE like it is in FF.
I've never liked IE, but the newest version has a particularly horrible user interface.
I installed Safari on my laptop to see what it was like, and while it is quite nice, if a little plain, there didn't seem to be anywhere to report problems, and so far I'm not sure whether Apple are supporting it on the PC.
I've just downloaded the latest version 2 of FF just in case it is as big a change as the last IE update, which I didn't like, and put me off using IE even more than before.
While there are loads of add ons and plug ins for FF, the only one I use is the dictionary/spellchecker. Just make sure you get the English (British) if you want to use it yourself as you may end up with some nasty American spellings.
