I get: "Your Web Browser is Out of Date! Some features of this site (and many others) may appear broken. Your browser may also have serious security flaws. We recommend you upgrade to the latest version of a modern browser."

This is on Firefox 29.0.1, Mac OS X 10.9.3.

Even if whatever is causing that message is fixed, the language of the message really needs changing. I am running the latest version of a modern browser, and so are the other potential users/customers that you've redirected away from your site!
