Before shutting down Firefox I deleted history/cache/passwords etc from the past day
I do this all the time but since I had restore previous tabs selected they always get restored when I start up again
However this time they weren't restored when I restarted
Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.
So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs
However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others
1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF
2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF
I also repeated the steps after creating a separate profile
None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'
Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work
I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update
The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software
