The Bugbug bot thinks this bug should belong to the 'Firefox::Session Restore' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for your report. If you can reliably reproduce the issue, then screenshots or videos are very helpful. Please attach any recent session restore logs from your profile directory, which - if they exist - should be in a a sessionstore-logs directory in your profile directory (the location is linked in the about:support page).

If you could record a video that shows how the browser looks before you restart it and after you restart it, that could be very helpful. Any additional details that you can provide about which tabs you are opening and loading would also help.
