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.

In Mozilla applications, -moz-user-input determines if an element will accept user input.

/* Keyword values */
-moz-user-input: none;
-moz-user-input: enabled;
-moz-user-input: disabled;

/* Global values */
-moz-user-input: inherit;
-moz-user-input: initial;
-moz-user-input: unset;

For elements that normally take user input, such as a <textarea>, the initial value of -moz-user-input is enabled.

Note: -moz-user-input was one of the proposals leading to the proposed CSS 3 user-input property, which has not yet reached Candidate Recommendation (call for implementations). 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.

The element does not accept user input. However, this is not the same as setting disabled to true, in that the element is drawn normally. Please note that this value is no longer supported in Firefox 60 onwards (bug 1405087).
