Usercolors no longer work on Firefox, NS_ERROR_FAILURE in vestitools_style.getXHR

[fracture91]

Firefox 14, try to interact with usercolors in any way (get, post, refresh). It says it's doing something, then never indicates it finished. In fact, no network request is made.

Looks like it takes the branch I'd expect Chrome to take (so XMLHttpRequest is defined now, it seems). Dies when returning the XHR. This bug, maybe: https://bugzilla.mozilla.org/show_bug.cgi?id=779552

I suppose I should just be able to branch on the value of this.chrome instead. Hopefully the XPCOM thing doesn't have the same problem.
