  1. On tabbing to the button NVDA 2013.2 in FF23 fails to read the aria-labelledby attribute when it refers to its own "value" attribute.
    NVDA reads the value attribute for the button and aria-labelledby does not override it.

# The accessible name is the concatenation of the value attribute and h3 text in this case. 1. NVDA fails to read the aria-labelledby for a button when it refers to itself. In this case again the accessible name is the contatenation of the visible button text and the h3 text.

This only occurs in browse mode. If we rendered the label as specified in browse mode, you would see the heading itself and then the heading content duplicated as part of the button, so I think the current behaviour makes sense. However, it should probably honour the label as specified when tabbing and perhaps quick navigation.

Here is a Web page with examples for buttons referred to in the bug report.
Refer to the Add to Cart buttons for Mini Laptop and Back to School Laptop in Section 9 of the page at

Also, this is not minor: NVDA fails to read the accessible name of the button based on aria-labelledby when one tabs to the button or uses quick nav.
And as NVDA does not announce the nearest heading, the context cannot be discerned by a non sighted user without moving focus away from the element.

Correcting version, since 2013.2 wasn't previously an option. See #3499.

This was fixed by #1354.
