Thanks for reporting!

Could you please attach any recent session restore logs from your profile directory, which - if they exist - should be in a sessionstore-logs directory in your profile directory? (the location is linked in the about:support page)

sessionstore-logs - no such folder in the profile directory.

Today again I had hard power off. And again - no tabs in Firefox. And cp sessionstore-backups/upgrade.jsonlz4-20250418071802 sessionstore does not solve it :(

Hmmmmm maybe it was because on i3wm Firefox was on another workspace...

It's not clear to me whether the issue was resolved or if it's still happening. @Vitaly Zdanevich, could you let me know if the issue has occurred again since your last update? If so, would you be able to provide some clear steps to reproduce it? Thank you.

Looks like Firefox was opened on another i3wm workspace because of my i3wm preferences.
