I had closed Firefox the night before, and when I opened it today, all of my tabs were gone. I again was able to restore from a previous version Windows had archived last week of the recovery.jsonlz4 file in the sessionstore-backups folder. This restored 88 of about 110 tabs, but I lost all of the more recent ones. Does anyone know why this keeps happening, and how to prevent it? I guess if I were to continue to use Firefox, I'd need to bookmark all of my tabs each time I closed the browser. I'm going to have to switch to a more reliable browser. I'm running Firefox 68.0.2 in Windows 7.

I had already looked at my recovery.jsonlz4, etc., files, and put them through jscher's analyzer. They held records for only the few tabs I had opened after Firefox lost all of my previous ones. There didn't seem to be any recovery file for the lost tabs, at least not in the sessionstore-backups folder.
</p><p>But I did solve my problem, mostly, partly by accident. In an idle moment, in Windows Explorer, I looked at the properties of the sessionstore-backups folder, and discovered that Windows had archived a previous version just a few days ago. I then used the method you outlined to restore from that file, and recovered the majority of my tabs.
