<p>Yeah i know about this, i am in current profile! There is no sessionstore.jsonlz4 or how it called. Only recorvery.balkz4/jsonlz4, which didn't contain my bookmarks. I was told to backup these in future, but i fear my bookmarks were permanently lost!

<blockquote>When you close Firefox then Firefox creates sessionstore.jsonlz4 at the root level in the profile folder from the recovery.jsonlz4 file in the sessionstore-backups folder.
When Firefox is running then you won't find sessionstore.jsonlz4.
Each time you update Firefox then a upgrade.jsonlz4 should have been created, so if you do not have these upgrade files in the sessionstore-backups folder then this would suggest that this is a recent profile.

</p><p>You will normally find these files in the sessionstore-backups folder:
</p>
<ul><li>previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
</li><li>recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
</li><li>recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
</li><li>upgrade.jsonlz4-&lt;build_id&gt; (backup created during an upgrade of Firefox)
</li></ul>
<p>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 (make sure to backup the current sessionstore.jsonlz4).
</p><p>You can look at this tool to inspect a compressed sessionstore file.
