Tabs of appimage, deb and local/portable Firefox (and Firefox-based browsers) crash in Kubuntu 24.04

[cipricus]

The bug or problem doesn't affect Firefox snap (although initially I though it did).

It doesn't affect flatpak versions of Firefox or Firefox-based browsers.

But Firefox (appimage and local/portable) and browsers based on current Firefox, as well as nightly version of Firefox (installed as deb or local/portable) don't work after update to Kubuntu 24.04. This happens in both X11 and Wayland sessions, with both empty/new profile and my customized one.

The errors are of the form:

Status changed to 'Confirmed' because the bug affects multiple users.

Same in Ubuntu desktop (GNOME), so not Kubuntu-specific.

This is related to the kernel version 6.8.0-11-generic.

6.5.0-17-generic is not affected.
