It works for me also with Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 and the Firefox startpage. 
Try it without extensions ?

Yes, I tried without extensions on different machines.

Interesting thing: when I use it on major sites - such as www.google.com - it also returns "0".

In previous versions of Firefox - document.body.clientWidth worked fine.

Strange..
