How to remove focus outlines in firefox 13
===

This is going to smell like a duplicate but it isn't. I've tried this:

    input:focus {
       outline: none;
    }

and it doesn't work in Firefox 13. See:

Firebug leaves me guessing what default is being applied here that I need to override. Just to be clear: I want to get rid of the blue outline completely.

P.S. Please do not hector me about accessibility. I'm doing this *for* accessibility. The design page that has a light blue background, and the browser default outline color doesn't visually appear against it.
