I commented out the importing of a .css file which made the tab bar multi-rowed. I did that because I was having trouble moving tabs to where I wanted them. The unexpected side effect was that tabs previously closed no longer appeared in the next session.

<p>Thanks. The sessionstore.jsonlz4 file is the same date as the other files (July 22, 2018) and time is 8:39AM that day. The recovery.baklz4 time is 8:38AM and the recovery.jsonlz4 time is 8:39AM.
I did create a new profile for Firefox Quantum and last used it on April 18, 2018.

<p>Thanks and sorry. I last used Firefox Quantum at about the times shown. I subsequently reverted to Firefox 56 on another system, using a different profile folder. Before that, at one point after exiting the browser there was no file named sessionstore.jsonlz4.

<p>Does your Firefox complete its standard shutdown file maintenance? This includes:

</p><p>(2) The recovery.jsonlz4 and recovery.backlz4 files are removed from the sessionstore-backups folder

<p>Thank you.
1. A new file named sessionstore.jsonlz4 is present.
2. The recovery.jsonlz4 and recovery.backlz4 files are still present in the sessionstore-backups folder. There is also a file previous.jsonlz4 which is earlier in time than the other files, one of which is a minute earlier in time. It may help if I attach a screenshot.

Hi ender21, the main purpose of the Scrounger page is to show you what windows/tabs are in a session history file, and optionally to archive them as clickable links in an HTML document.
In the case of the problem you're experiencing -- unexpected tabs are restored -- checking this file after you have shut down Firefox normally could reveal whether the unexpected restored windows/tabs are coming from this file.
Since you need to get the sessionstore.jsonlz4 while Firefox is closed, you could run the Scrounger in Chromium, or you could back up the file somewhere, restart Firefox, then scrounge the file in a Firefox tab.
</blockquote>
<p>If they aren't coming from that file, where else could they come from? I have experimented with renaming the file then relaunching Firefox but that only got rid of one of three unwanted tabs.

<p>Thanks once again. This solution is beyond my capacity. No "uncompressed sessionstore" file was generated. It generated another HTML page (not a file) which simply contains links to the open tabs. I opened a tab in Firefox 56 and then opened 'Inspector'. I have no idea what to look for there.
I do NOT have this issue in the profile I use with Firefox 56.
I have created another new profile for Firefox Quantum and it has the same issue. Strangely, it has no sessionstore.jsonlz4 file.
