CSS CSS Basics (2014) Basic Layout box-sizing and max-width

Browser support for box-sizing: border-box

The last paragraph of this great webpage that explains box-sizing that was posted in the teacher's notes mentions the following:

Support is also great, as all major browsers (except IE7) support it. Currently, Firefox is the only browser that needs a vendor prefix, so make sure to also include the “-moz-” prefixed declaration.

What does the author mean by include the "-moz-" prefixed declaration?

I don't think it's needed any more, but what they mean is that instead of "box-sizing" you would write "-moz-box-sizing".
