Re: Why does the forum crash?
I prefer Firefox too. It has more useful add-ons than Chrome (though Chrome is quickly catching up) but what I really like is that it's completely open. This might not mean much to most of you but I always try to use an open-source equivalent as long as it's as good as the rival products.
I'd certainly switch from Internet Explorer, especially if it's not the latest version. Back then there wasn't much browser competition for IE and as a result the older releases are very insecure.
