Firefox 1.0 is GBrowser?

I had heard rumor's of Google producing it's own web browser, nicknamed "GBrowser" by the community. Not until I installed Firefox 1.0 did I notice the new start page that Google had made for the browser. It looks nice and all, but I didn't put the two together until I saw one of Vasanth Dharmaraj's Blogs, "Firefox 1.0 is GBrowser?" Now it sort of makes sense.
