1653793 - TB 78: startup error in error console. TypeError: singletons is null, init resource://gre/modules/ActorManagerChild.jsm:297

Status: RESOLVED WORKSFORME

(Thunderbird :: General, defect)

Description

[ISHIKAWA, Chiaki]

I installed TB 78 (32-bit), Japanese locale version, a few days ago under Windows 10 (64-bit)
I noticed the error reported here in error console immediately after startup of the program (no interaction after the startup).
(See Bug 1653789, TB 78.0: Errors in error console immediately after startup of TB under Windows 10.)

However, this particular error seems to be caused by async race.
Sometimes I see it, and other times I don't.

No, as the attached screen dump shows, it is gone.
I have switched to 78.8.0 (32-bit) and so something must have fixed it for now.
