Good but not perfect Rated 4 out of 5 stars

The 'Colour Contrast Analyzer' ignores css background gradients on elements.

Also, the ARIA 'Live Regions' display ignores my 'role="alert"' div that is displayed via JavaScript when a form error occurs. It only works if the redundant 'aria-live="assertive"' attribute is added. It seems that the extension needs to be updated to work with current ARIA syntax.
