[Bug 2056190] Re: Tabs of non-flatpak Firefox (and non-flatpak Firefox-based browsers) crash in Kubuntu 24.04

[cipricus]

** Description changed:

  I have installed Firefox snap version in order to be able to post the
  bug report on that program, but the bug or problem affects all browsers
  based on Firefox that I was able to test, with the notable exception of
  the flatpak versions.
  
- Firefox (snap and local) 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.
+ Firefox (snap, appimage and local) and browsers based on current

  The errors are of the form:
