[Bug 1959747]

[Vseerror-i]

That's good work.

Bad news: the number of
[Firefox](https://hg.mozilla.org/releases/mozilla-
beta/pushloghtml?fromchange=FIREFOX_110_0b4_RELEASE&tochange=FIREFOX_111_0b1_RELEASE)
and [Thunderbird](https://hg.mozilla.org/releases/comm-
beta/pushloghtml?fromchange=THUNDERBIRD_110_0b4_RELEASE&tochange=THUNDERBIRD_111_0b1_RELEASE)
patches in that span is massive.

Good news: 111.0b1 is the first beta with Supernova code.  So there is a
high chance the cause is Supernova code whose first daily build is
2023-01-16.

Bad news: I'm guessing the cause is straight up Supernova "ash" massive
code landing on 2023-01-17.  So you might try **nightly** builds on
either side of 2023-01-17.  If the problem is not seen there, use
mozregression to try **nightly** builds between  and 2023-02-27
