I reinstalled Firefox version which is 73.0.1(64-bit). Before reinstalling I backed up my "sessionstore-backups" folder. Now I am trying to restore my previous session with the backup older by using files "previous.jsonlz4" and "upgrade.jsonlz4-20200217142647" but unable to restore. I even tried with disabling all add-ons but still unable to restore. Am I missing something? Thanks in advance.

Thanks Robert for the reply. This is what happened actually. I was getting continuous alerts from Avast regarding Firefox so I took backup of "sessionrestore-backups" folder and uninstalled it . After uninstallation I also removed "Profiles" folder from both "Local" and "Roaming" folders in "AppData". Later I reinstalled the Firefox again and instead of copying session from my backup folder, I did a drag and drop into "sessionstore-backups" folder. Thereafter I deleted them and lost those files. Later I ran "DiskDrill" program and recovered them. I tried again and failed to restore. After I went through your link and used the "Scrounger" on my back up file "previous.lz4", it is giving empty data. It looks like recovery was poor. Maybe the session is long gone. Thanks again.
