How can I restore session from a different profile?

I created a new profile and would like my previous session tabs - from an old profile - to open there.

However, there is no sessionstore.js file in the old profile (however, it gets restored there somehow).

Please let me know which files do I need to copy to the new profile for this to work.

Firefox is Quantum 60.0.2 (64-bit). I have copied all bookmarks, history and passwords successfully - just need the session restore data.

Thank you!

As noted by Pkshadow, the file name has changed in Firefox 56 and later (the file is is now compressed using LZ4 compression).

If sessionstore.jsonlz4 is not present, Firefox may not have shut down normally in that profile. In that case, look in the sessionstore-backups folder for a file named recovery.jsonlz4 which would be the last capture of tabs in that session. Can you find that?
