-moz-user-input - CSS: Cascading Style Sheets
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).
...*/ -moz-user-input: disabled; } specifications not part of any standard.
