It's 2014, and I just updated my FireFox to 27.0.1 (latest stable version). I'm running this on Ubuntu. When I open javaScript console and type: 

   new XMLHttpRequest().upload

I'm getting: 

   undefined

Let me just add that doing the same on MacOs or with Chromium on the same Ubuntu gives me: 

   XMLHttpRequestUpload { onloadstart=null, onprogress=null, onabort=null, more...}

Is that a bug? Some well know politics? Can you help?

Works here with the Web Console (Firefox/Tools > Web Developer).
