UI costs Citibank $500 million

Difficulty navigating a UI by a bank employee costs Citibank half a billion dollars.

This was apparently caused by incorrect fields being filled in, a potential failure of WCAG 2.1 SC 3.3.2: Provide labels or instructions when user input is required

How much would it have cost to run an audit and/or usability test on that UI? Probably not $500 million.

Firefox showing the tabbing order

Firefox has added a “show tabbing order” option to the accessibility panel. This overlays a number onto each focusable element, showing its place in the linear tab order of the page.

But it’s early days yet, so these will be hopefully resolved.
