I've been using firefox for about six months now, and I like it more everytime I use it. It has never crashed, and it coexsits beautifully with windows. It once "forgot" all my bookmarks, but only once, and there was something going on with my computer (maybe an windows update) that could have been the real cause. Otherwise, it's been just fine. Most likable features: Downloads are significantly faster than Windows. (What is windows doing that slows down downloads so much?) Plus, you can load it up with jobs and it'll do them all automatically. (As opposed to IE, that will only let you set up 2 jobs at a time). Real time spell checking. Updates are automatic and benign. I comes up quick. In short, IMHO, it's a great product. Further...when I travel I'm stuck with my work computer (Ugh!), and I can't put Firefox on it. I'm getting to hate IE!
