Comment 5 Piotr Mierzwinski 2025-10-14 20:46:22 UTC 
Today Firefox has been restored - yesterday I was opened 5 windows and today all of them have been restored. Now I'm not sure if this was distro problem or issue was fixed by accident. I don't close this bug report yet, let see what will happen tomorrow.
Comment 6 David Edmundson 2025-10-14 21:57:46 UTC 
There was a relevant change in ksmserver, it's not just gone away by accident.
