-- Information about the crash:
Firefox has been flinky lately, especially when I have something like
https://battalionmetals.com/analytics?chartType=gold&startDate=3M open. By
that, I mean I get a lot of tab crashes on that particular tab. I don't recall
all of the apps I had running, but they included, Mathematica 14.3, Okular,
Dolphin, Chrome with the Grok App, Kile, and Emacs with the LaTeX PDF viewer.
I was editing a LaTeX document in Kile at the moment of the crash.
What happened is that my secondary display went black, though I could still see
the mouse pointer, which was responsive to motion. All of my applications
crashed. Kile, Okular and Dolphin restarted. Firefox asked me to restart it,
saying that it had crashed. That's why I blame Firefox.
When my applications restarted, they were all placed in the primary display.
`Alt+F2=>plasmashell -replace` restored the seconday display.
The reporter is unsure if this crash is reproducible.
