You can check this article.
About your lost tabs, open tabs are stored in sessionstore.jsonlz4 as part of session data.
You will normally find these files in the sessionstore-backups folder:
- previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
- recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
- recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
- upgrade.jsonlz4-<build_id> (backup created during an upgrade of Firefox)
You can copy a file from the sessionstore-backups folder to the main profile and rename the file to sessionstore.jsonlz4 to replace the current file with Firefox closed.
- make sure to backup the current sessionstore.jsonlz4
You can look at this tool to inspect a compressed jsonlz4 sessionstore file. This tool works locally, no uploading done.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

Maybe I panicked too soon. In history, I found a box to open previously closed window (I only had one window open; so the new version opened another window?) When I clicked that box, another window went open, Windows went crazy as Firefox used over 90% of CPU and over 80% of memory. Of course, nothing seemed to be happening for a few minutes, while windows tagged Firefox as "not responding". I walked away for a few minutes, and when I came back, my tabs were all available.
Thanx for the help you offered. I am not a computer savvy guy, just good with plastics processing technology. So I am not sure that I could have followed what you offered, and am really thankful that it was only a new opened window that confused me.
