1828935 - Conformation hint disappears too fast, posing a11y hazard

Status: RESOLVED FIXED

(Firefox :: General, enhancement)

Description

[Dão Gottwald [:dao]]

We've recently wanted to use ConformationHint in the address bar, but joshberman pointed out it's an a11y hazard:

WCAG A criteria
WCAG AAA criteria
Note, there is no AA for this success criterion.

This criteria equally applies to time limits on forms and automatic / timed movement like inline alerts that disappear or carousels that move automatically

It could be argued that this is not part of the criteria but I think that’s really not in the spirit of accessible design. We know people with certain disabilities struggle with content that appears/disappears absent any action on their part. It’s best to not include those patterns if possible.

We might want to add a mode that requires some kind of interaction, but as a first stopgap I think we should increase the timeout. 1.5 seconds or 4 seconds, respectively, are really fast even if this feature is intended for short messages that we consider okay to miss.
