Well, I hardly use Microsoft's Internet Explorer anymore. There are some minor occasions where I am forced to use it (for instance badly programmed websites that need IE). Otherwise, I am a true convert to the quicker, safer, cooler, and more feature rich Firebird. I used it on all my Windows boxes now and really enjoy it. It does everything and the extensions are pretty cool -- like an ad-blocker and image-blocker are available. I can't live without tabbed-browsing now and the Google search box is indispensible! Not to mention the speed of the Gecko rendering engine and just the pure stability of a pre-1.0 product. Firebird is the future, give it a try!
