Yes, I have noticed the very same issue.

When the Mozilla Enhancements add-on was used with older versions of Thunderbird, the state changes of columns were automatically reported. Therefore I have to downgrade to an old version of TB in order to change the order of shown columns and then return to the latest version. When downgrading to the old version of TB I have to enable the Mozilla Enhancements add-on and disable it when returning to the latest version of TB, which is a bit complex even for an advanced user of NVDA.

One solution would be to add event_nameChange to IAccessible.mozilla.Mozilla class. If stateChange event is executed in event_nameChange state change (checked/unchecked) is reported both in speech and braille (tested locally).

I am not familiar with app modules but thunderbird app module would sound logical place to do this.

I have tested this locally but I have not succeeded with nameChange event in thunderbird app module for now.

No problem if this is something somebody else wants to fix, and if there is more appropriate approach.

Now it seems to work.

Is there something I could do to get this issue triaged? I think I have implementation for this (I do not say it is appropriate but it seems to work somewhat).
