-moz-user-focus

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Summary

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.

Initial value	`none`
Applies to	all elements
Inherited	no
Media	interactive
Computed value	as specified
Animatable	no
Canonical order	the unique non-ambiguous order defined by the formal grammar

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.

Specifications

This property is not part of any specification. A similar property user-focus was proposed in early drafts of a predecessor of the CSS3 UI specification but was rejected by the working group.
