My goodness, no one has mentioned the beautiful layout of the bookmarks column that I keep open to the left of my window. That, along with the security and tabs is my top three fav's about Firefox. The best thing about adblock, for anyone considering using it is that it won't load a new page it knows is fowl but still asks your permission to allow any new site with a humanistic explanation, then remembers your preferences. The tabs allow you to bring up several site pages so you can bounce between them w/o closing them - a must for product comparisons. IE is the contaminated info superhighway, so much so that I can't see how it will last into the future. Firefox is like staying safe at home. It's directly affiliated with google, and google is so keen on keeping it's site banks clean that the porn industry has attempted to sue. The progress is very interesting to watch.
