Restoring previous session after closing firefox.
My computer needed to be updated so I click on update without closing any programs because the computer usually does it. At this time I was in the School Library well the update was completed so I open up Firefox usually when i open firefox after a shutdown or some other reason. I can go to Open Application Menu>History>RestorePreviousSession but before I clicked on Restore Previous Session I realize that I need to go to class, so I closed my computer. once in class I open my computer up and I try to restore my previous session but by the time that I tried to restore it my session was deleted and my question is if anyone at FIREFOX can help restore that deleted session because I was working on my research project which is due this week, and in that particular session I had tabs open that I need so i can finish my project. Please reach out as soon as possible. This happen on Tuesday. Thank You

It's my computer.
The only way to restore a lost session is via an upgrade.jsonlz4 in the sessionstore-backups folder or by browsing a Windows System Restore point to see if you can locate an older copy on sessionstore.jsonlz4.
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).
- Help -> More Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-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 look at a utility to browse System Restore points.
