My current CSS includes:
*{
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
If you visit http://jsfiddle.net/KyF5x/ and click below the list, you'll see that the text gets highlighted and can't be un-highlighted. Reloading the page and trying ctrl+a will also highlight the text.
This issue does not occur in Chrome, Safari or IE 10.
Note: I am using Firefox 18.
