The New Firefox Is Fantastic. So Is Every Other Web Browser.

This review comes very close to my experience. However, I would add one more point.

I used the new browser on two slightly older PCs (relatively old). On a 4GB machine, I almost fell off my chair because I wasn't expecting such a fine speed from FF. Like the author above, I got pretty excited thinking that FF is finally back.

I then tried it on 3GB machine, and I didn't get the same enthusiasm.

It boils down to what you're used to of already. Notwithstanding the other debates (Google, anti-Google etc - which is not my concern for this discussion).
