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.

The :-moz-user-disabled CSS pseudo-class is a Mozilla extension that matches elements representing images that were not loaded because images have been entirely disabled by the user's preferences.

Note: This selector is mainly intended to be used by theme developers.


:-moz-user-disabled {
  /* ... */


Styling user-disabled elements

:-moz-user-disabled {
  background-color: lightgray;
  padding: 8px;
