Firefox creates numerous session h2021-06-22T02:35:33-07:00jscher2000https://support.mozilla.org/zu/questions/1341519#answer-1423229<p>If the earlier session is completely gone, here's the next thing:
</p><p>Firefox creates numerous session history files, but because session history is only for the immediately previous session, it is unfortunately too easy to lose it. Could you start by making a backup of your existing session history files? Here's how:
</p><p><strong>(1) To open your profile folder...</strong>
</p><p>You can open your current Firefox settings (AKA Firefox profile) folder using either
</p>
<ul><li> "3-bar" menu button &gt; Help &gt; More Troubleshooting Information
</li><li> (menu bar) Help &gt; More Troubleshooting Information
</li><li> type or paste <strong>about:support</strong> in the address bar and press Enter
</li></ul>
<p>In the first table on the page, find the <strong>Profile Folder</strong> row. On that row, click the "Open Folder" button. This should launch Windows' File Explorer listing the contents of your current profile folder.
</p><p><strong>(2) Copy out session history files</strong>
</p><p>In your profile folder, double-click into the <strong>sessionstore-backups</strong> folder. Save all files here to a safe location such as your Documents folder.
</p><p><strong>(3) What files did you find?</strong>
</p><p>The kinds of files you may find among your sessionstore files are:
</p>
<ul><li> recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session)
</li><li> recovery.baklz4: a backup copy of recovery.jsonlz4
</li><li> previous.jsonlz4: the windows and tabs in your last Firefox session
</li><li> upgrade.jsonlz4-<em>build_id</em>: the windows and tabs in the Firefox session that was live at the time of your last update -- If you recently installed the Firefox 89.0.1 update, there could be a recent snapshot.
</li></ul>
<p>Could you take a look at what you have and the date/time of the various files to see whether you think any of them would have the missing tabs?
</p><p>To preview the contents of a file, you can drag and drop it onto a tool on my site, then click Scrounge URLs:
</p><p><a href="https://www.jeffersonscher.com/ffu/scrounger.html" rel="nofollow">https://www.jeffersonscher.com/ffu/scrounger.html</a>
</p><p><em>If you don't get a list within 15 seconds, that probably means the script is caught in a loop. You may need to close the tab to avoid a tab crash and then try again in a new tab.</em>
</p><p>If you get a useful list, use the Save List button to archive it as a web page of clickable links for future reference, in case no other approach is successful.
</p><p>And we can describe how to trick Firefox into using one of those older files if you have a promising one.
</p>Could you check whether either of these are available (not hidden or grayed out):
"3-bar" menu but2021-06-22T02:33:18-07:00jscher2000https://support.mozilla.org/zu/questions/1341519#answer-1423226<p>Could you check whether either of these are available (not hidden or grayed out):
</p>
<ul><li> "3-bar" menu button &gt; History &gt; Restore Previous Session
</li><li> (menu bar) History &gt; Restore Previous Session
</li></ul>
<p>If they are missing or grayed, check either:
</p>
<ul><li> "3-bar" menu button &gt; History &gt; Recently Closed Windows
</li><li> "Library" toolbar button &gt; History &gt; Recently Closed Windows
</li><li> (menu bar) History &gt; Recently Closed Windows
</li><li> (Windows) Ctrl+Shift+N
</li></ul>
<p>Each window also has its own Recently Closed Tabs list, if you closed a bunch of tabs in a single window.
</p><p>Any luck?
