Mozilla firefox 13++ not support -moz- tag

Now mozilla has been updated to 13, and i'm surprised because all my CSS with -moz- tag is doesn't work anymore, and then when i check, "mozilla is not support -moz- tag anymore, but mozilla will support normal tag". For example, if you want to make border radius is must: -moz-border-radius, border-radius, -webkit-border-radius, but now mozilla only support border-radius tag, and now you can remove any -moz- tag in your CSS!.
