Description  

The -moz-user-focus CSS property is used to indicate whether the element can have the focus.

By setting its value to ignore, you can disable focusing the element, which means that the user will not be able to activate the element. The element will be skipped in the tab sequence.

Note: This property doesn't work for XUL textbox elements, because the textbox itself never takes focus. Instead, XBL creates an anonymous HTML <input> element inside the textbox, and that element is what receives focus. You can stop the textbox from taking keyboard focus by setting its tab index to -1, and from taking mouse focus by preventing the default action of mousedown events.
