Re: [orca-list] Strange behavior of Orca on a weird website

[Joanmarie Diggs <jdiggs igalia com>]

Hi Jean-Philippe.

Looking at your debug.out, Orca is getting flooded by children-changed
events, many of which are for dead or defunct objects. My guess is the
site is updating a significant amount of content and/or doing so
extremely frequently. And my guess is that the reason the problem only
happens when Orca is running is because Firefox isn't emitting
accessible events for all of those DOM mutations taking place on the site.

HTH.
