Firefox wins by far, it's just overal better. Although the new IE has those features of Firefox now, I just like Firefox. I also think it's less buggy, right?
I keep both IE7 and Firefox around. I have found that there are some sites, or things that Firefox does not work well with. So I then fire up IE. But for the day to day chores on my computer, it's Firefox.
At the risk of starting trouble, I would pigeon hole the following. People in the "know" use firefox, people who have no real clue use IE. Simple computer users use IE, I have never met a basic computer user who used FF, ask someone you know in this category about using a different browser and they are like (insert homer voice) "what in the who know?" As these are the majority of internet users, and its default with windows, IE will always be the majority. Firefox just has so many tools that make life so much easier, why would you not use a tool to make life easier? Hope I didnt offend.
I use Mozilla on my laptop, firefox on my desktop, and IE at school....am going to go all firefox real soon...
The one and only Firefox - once used never look back. Together comrades we can crush the dominance of IE!
FF has lots of friendly gadgets to explore. Definitely my choice. And I am proud to have 'converted' my department to become firefox users.
