When hovering over an anchor the status bar displays the link.  However if JavaScript subsequently changes the href of the anchor the status bar is not updated.  If the link is to a trusted site, but the JavaScript subsequently changes it to an untrusted site the user would not know what they were clicking on.  This is not really any different than an onClick handler of an anchor taking the user somewhere else, but here we do have the link.  IE 7 and Opera 9.63 do not suffer with this.

Reproducible: Always

Steps to Reproduce:
1.  Create an html file with this content:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<html xmlns="">
  <script type="text/javascript" src=""></script>
  <script type="text/javascript">

$(function() {

    $('a').hover(function () {
        this.href = ""
    }).mouseout(function () {
        this.href = ""


    <a href="">Look at the status bar URL and then see what this opens!</a>


2.  View that page in Firefox
3.  Look at the status bar with the mouse over the link
4.  Click the link
Actual Results:  
The browser is redirected to the "unseen" location.

Expected Results:  
The status bar should present the current href of the anchor

The status bar should be updated when the anchor's href is updated.

This is not a duplicate of bug 229050.  That bug is saying the presence of an onclick handler setting location.href is misleading the user.

This bug is to do with some JavaScript changing the href, but the browser not showing the change.  The difference is subtle, but it is different.
