Good afternoon!

I have accidentally closed tabs and during next launch I omit restore session button in Firefox 38.05 and now Restore session only recovers initial home page of Firefox. I have reviewed contents of sessionstore-backups folder is it possible to recover all tabs at least from file upgrade.js-YYYY ? Is it possible to rename file upgrade.js-YYYY to sessionstore.js and try to press recover tabs in Firefox menu to recover at least tabs that were opened during upgrade? Thanks in advance for your reply!

You can copy any of the files to sessionstore.js in the main profile folder with Firefox closed to replace the current file to make Firefox use that session.

Best is to make backup copies of all the files in the sessionstore-backups folder to prevent losing session data.

Thank you for your reply! You mean that I can rename the desired file upgrade.js-YYYY to sessionstore.js and replace my new sessionstore.js with the old one in root folder of Firefox? Is it correct? Or I need just to copy upgrade.js-YYYY with out any name modification directly to root folder?

The name of the sessionstore file needs to be sessionstore.js, so you need to rename the upgrade.js file to sessionstore.js after having copied the file.
