Aria-Live in Firefox not read by screen reader

2.2k views Asked by Nachshon Schwartz At 03 September 2019 at 08:30

I am having an issue where the Screen Reader is not reading the text that changes within aria-live section in FireFox.

This is a simple example for a page where in chrome the Screen Reader reads the changes as they come in and in FireFox it does not:

<div aria-live="assertive" id="moo">

</div>
<script>
  let i = 0;
  setInterval(() => {
    document.getElementById('moo').innerText = 'moo' + i++
  }, 2000)
</script>

Am I doing something wrong? Is there another way to announce changes when they come in besides for aria-live that people use with Firefox?

I tested on Mac-Firefox-VoiceOver (it works on Mac-Chrome-VoiceOver)

Current firefox version: 83.0 (64-bit)
Firefox Nightly version：85.0a1 (2020-11-29) (64-bit)
In the latest Nightly version, the combination of aria-live on firefox + voiceOver is fixed! Hooray!
