*** Bug 457449 has been marked as a duplicate of this bug. ***
Comment 2 Dennis 2024-05-02 08:12:44 UTC 
I see the same issue. 

I updated the system today and I'm on:
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 6.0.80
KDE Frameworks Version: 6.2.0
Qt Version: 6.7.0
Kernel Version: 6.5.0-28-generic (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-8565U CPU @ 1.80GHz
Memory: 15,3 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620
Manufacturer: Dell Inc.
Product Name: XPS 13 9380

As there is no bug reporting address:
https://bugs.kde.org/show_bug.cgi?id=443053
I'm reporting this issue manually. I can't confirm it is actually firefox, but it looks like it. I have firefox on autostart and I use the save session feature from kde. Whic results in 2 firefox windows to be started after logging in, one of them with empty tabs. If I close that one, 10 crash handlers start.

the crash report:
