I disagree. There are 400-450 million Firefox users that absolutely will benefit in huge ways from this update. There may have been a time for a while there where some chunk of those users felt like Chrome could offer them more, but that time is gone now.

I'd go a step further and say that now there are going to be an increasing number of Chrome users who will compare to Firefox 4 and want the performance and feature improvements that it has over Chrome and that may hold true for some time.

So, yes, you could look at it that way.
