STR:
- Launch Firefox
- Navigate to about:preferences
- Launch VO
Expected: VO focuses the page content and allows you to navigate
Actual:
Assertion failure: parents1.Length() != 0 && parents2.Length() != 0 (have empty chain of parents!), at /Users/mraereschenberg/test-moz/accessible/mac/GeckoTextMarker.mm:167

If you've already got VO enabled and then launch/navigate, this doesn't happen.

Nominating for inclusion in work for 86, but can be bumped back down if not deemed critical enough.

I wasn't able to reproduce the issue on Firefox 85.0a1 (2020-12-07) under macOS 10.15.7 and 11.2. Here's a screen recording with what I did.
Morgan, could you please look over and see if this is fixed for you in the latest Nightly and Beta builds?
Or if there is something that I missed in the recording and can be seen, please let me know and I'll retry. Thank you!

Hi! Yes I can confirm this is fixed :) This was sort of intermittent to begin with, and normally it'd happen if I pressed cmd+, and cmd+f5 to both launch preferences and start voiceover quickly after.
