Mozilla shipped 1.0 of their Firefox version yesterday.
Since downloading one of the preview versions I haven’t missed or wanted to go back to IE at all… Firefox is a leap ahead of IE, and the tabbed browsing is awesome.
I wonder how Microsoft is going to respond to this new challenger in the browser space, since MS has already announced that it will not be continuing development of IE as a standalone downloadable software component, but will instead be an integrated feature into new Windows versions (ie Longhorn)
