Firefox notifications with x-dwm became intrusive around 122.0

Question

Before I turn to the esoteric mailing lists I present you with an opportunity to lower my already tarnished reputation:
my Firefox notifications using DWM used to be exemplary - a small non-intrusive window at the top right that then went away by itself quickly. From around FF 122.0 on they now create a whole new window that also becomes master, thus stealing focus and eg interrupting while I might be typing somewhere else.

Is there someone who knows what FF setting might have changed that affected this behaviour please?

Answer 1

Not so much an authoritative answer as maybe a workaround/gordian knot cut but I went over to start using dunst as a notification daemon instead and it was pretty straightforward. Just relying on the default behavior of the Window manager + browser turned out to be unsatisfactory in the end.
