I have downloaded Firefox 4 and when I open Firefox again I get the message that my version is not safe from online attacks, so why?

I opened Firefox and got the message that I needed to download 4 because my version was not safe from attacks. I downloaded 4 and then I quit Firefox and reopened it, and got the same message as before. I am probably doing something incorrectly, but I have no idea what that could be. Thanks.
