Finally! I've been love with Firefox since someone on this board mentioned months ago. I did have a re-occurring problem with it locking up and scanning my harddrive for 30-60 seconds at time when I'd scroll my bookmarks and some websites. Not all of the time, but several times a day. But I just found the answer on their forum yesterday. Too many fonts enabled on my system. I disabled my extra few thousand fonts in Adobe Type Manager and now it works like a dream come true. I'll have to re-enable them for graphics work, but that is better than using IE.
Firefox is also excellent at picking up minor errors in webpages. Makes you build better pages.
