If a web site doesn't work on the Mac using Firefox 2, it probably doesn't work on the Mac, period. Most web sites/corporations that intend to support mac users in some way ensure their site works in Safari. Those that are too lazy for this, it may work in Firefox. If it only support Windows-specific features (like ActiveX), then get an Intel mac, Parallels, and Windows XP -- and use IE 6 on Windows.

I doubt anyone would waste time and resources emulating IE5, which was stable in its time but an antique now. Where I work we develop for IE6 (windows), Firefox (mac/win) and Safari. This also means Opera, Konqeror and some smaller browsers probably work, too.
