Why Does My Custom Cursor Image for Image Magnification Not Work in Firefox?

Custom Cursor Image for Image Magnification

If you aim to enhance user experience by replacing the default cursor with a custom image such as a magnifying glass when hovering over certain image elements, CSS can offer a solution. However, unexpected behaviors may arise.

In the instance described, a cursor URL is defined using CSS:

a.heroshot img {
  cursor:url(/img/magnify.cur), pointer;
}

Although the magnify.cur cursor is correctly located, this code renders ineffectively. Inquiries reveal that this behavior stems from compatibility issues with Firefox on the Mac platform. For Firefox, a JavaScript solution or an alternative approach is required.

Firefox Compatibility

For Firefox, the cursor URL mechanism is not supported. As an alternative, the "-moz-zoom-in" keyword can be used to achieve a similar effect.

cursor:url(/img/magnify.cur), -moz-zoom-in, auto;

With this modification, Firefox will prioritize displaying magnify.cur, followed by the Mozilla-specific zoom cursor, or a fallback system cursor.

Browser Compatibility

Cursor keywords and their support vary across browsers. For a comprehensive reference, consult the linked resource provided in the original answer, which details compatible cursor keywords for various browsers.
