1642707 - Firefox no longer sends VoiceOver a notification that the page finished loading.

Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect, P1)

Description

[Marco Zehe (:MarcoZ)]

This was implemented by Hub Figuiere in 2012 or 2013, but got broken some time ago, probably in E10S.

STR:

1. In Safari, load any web site with VoiceOver on.
   • Result: When the page finishes loading, VoiceOver emits three ascending tones that indicate that it is ready to read the page.
2. Do the same in Firefox.
   • Expected: We'd hear the same ascending tones.
   • Actual: No tones are being played.

I think this was broken even before Eitan's refactor in Bug 1624729. It was fired on the native accessible element. According to Chromium source, "AXLoadComplete" should only be fired on the root element, and "AXLayoutComplete" on iframes. We're firing all in both cases, and that might be wrong nowadays. Chromium changed that some time in 2015 or so.
NI'ing Eitan since we just talked about this on Zoom.
