Re: Firefox visual focus indication

Using the default browser focus indicator is a sufficient technique: https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G165

It becomes a failure when the focus indicator is suppressed via CSS through means of outline: none, for example (see www.outlinenone.com for more details!).

If you roll your own, you need to ensure that it's "highly visible". WCAG does not define this term, but we have interpreted it to mean that we should strive for a 4.5 to 1 color contrast ratio.
