How can you say firefox has flaws? It has a great built-in pop-up blocker, constant updates, you can customize it to your liking to make it suit your needs (optimize speed based on how good your computer and connection is), lots of great skins and a cool quick search bar for popular sites like google and amazon and others, I mean the list goes on. It's one thing to just say you prefer msn explorer or IE, that's fine, but to say it has flaws? I don't think so.
