<p>Is your Firefox set to automatically restore your previous session on the Options/Preferences page:

I was working at another site last Friday, so I didn't have the issue, but other than that, it's been happening daily.

<p>It sounds possible that the session history file is corrupted. But only on Mondays? Still very mysterious.

</p><p>I do see all those options (in the 3-bar menu button, the library toolbar button, and menu bar-&gt;history), but they only have been showing the most recent websites I've visited (usually tabs I have closed). I've tried "restore all tabs" but that opens multiples of the same tabs and tabs that I closed and do not need open, and it cycles through them non-stop, to the point where the only way to end it is to close Firefox.
</p><p>I don't have any "cleaning" programs installed on this PC. I also use Firefox at home on my personal laptop (Macbook Pro) and I'm not having this issue (or I haven't yet, probably just jinxed myself, heh).
</p><p>I haven't lost any other data, and once I reopen my tabs manually, my log-ins are still saved.
</p><p>I am allowed to install add-ons, so I will give those a try, and see if they help.
</p><p>Thank you for the advice!
</p>Hi SharynK, first, I'm sorry to hear about this problem.
If Restore Previous Session is not availabl2019-06-10T06:40:49-07:00jscher2000https://support.mozilla.org/vi/questions/1261571#answer-1229127<p>Hi SharynK, first, I'm sorry to hear about this problem.
</p><p>If Restore Previous Session is not available, that usually means either:
</p>
<ul><li> Firefox didn't find a session history file to restore
</li><li> Firefox already restored the session history
</li></ul>
<p>In the second case, you might see data here:
</p>
<ul><li> "3-bar" menu button &gt; Library &gt; History &gt; Recently Closed Windows (and within each restored window, Recently Closed Tabs)
</li><li> "Library" toolbar button &gt; History &gt; Recently Closed Windows (and within each restored window, Recently Closed Tabs)
</li><li> (menu bar) History &gt; Recently Closed Windows (and within each restored window, Recently Closed Tabs)
</li></ul>
<hr>
<p>In some cases, data loss after restarting Windows can be caused by "cleaning" programs that touch browser data (e.g., CCleaner, Advanced System Care). However, on a work PC, that seems much less likely than on a home PC.
</p><p>Are you losing any other data at startup?
</p><p>There is a bug in Firefox 67 where the session history might stop getting updated due to a problem extracting form data from a page. However, since your issue only occurs after a Windows restart, I suspect that isn't the issue.

<p>Are you allowed to install add-ons? There also are session management extensions you could consider as an emergency workaround until this is sorted out. These are the ones I'm aware of that you might investigate/try out:
