I use Firefox 99% of the time. 1% of the time only IE will work correctly with a site. You may find that about 10-15% of sites don't seem to work correctly with firefox. Then get "IETab". That way you can tell firefox to use the IE rendering engine to render a page. That fixes 99% of those problems.
There are lots of "extensions" or add-on's that I also like.
Adblock Plus and filterset.G for Adblock are must haves. They stop most ads on webpages.
I also like "tabkit" and "tinymenu".
With Tabkit and tinymenu, I'm able to put the list of tabs down the right side (or top or bottom or left side if I want), and condense the top several lines to only one line. By doing that I get more vertical space to view pages (since most pages are vertical) but most monitors are horizontally long.
I know lots of monitors will rotate, but there's also lots of stuff that's designed to be used in landscape mode. Ideally, we'd not have these "widescreen monitors", instead they'd all be square.
