Summary

-moz-user-select is a Mozilla property extension to CSS that is used to determine whether or not an element may have its content selected.

Media: interactive

Possible uses include: prohibiting the selection of content in attempts to reduce blatant copying.

-moz-all

Usage Examples

This sample code provides a simple "Hello, World!" text which prevents the user from selecting the content:

<span style="-moz-user-select: none;">
 Hello, World!
</span>

Notes

This property is similar to the user-select property of CSS3.

When the 'none' value was applied to a heading element the content could still be selected.

According to the W3C, the "User agent's default style sheet may override this value. For example, user agents typically do not allow selection of the contents of a BUTTON element. [1]
