Following the most recent update I've lost all my regularly open tabs and most of my tab history. Is there a way to restore my previous tabs?

Hi,

Please check out Recover user data missing after Firefox update or reinstall and How to restore a browsing session from backup.

Yep, this is happening to me too. I closed FF and went to bed. I opened it in the morning and lost about 20 tabs. Happens every time I restart FF now. I looked in Firefox help. It said I could go into History and click "Restore Previous Session" but that option doesn't exist. All I can do is look at History and restore 'some' of the tabs. Too many have disappeared.

I followed their next advice, went into Settings, Home and Startup, to select "Open previous windows and tabs". but it was already selected. So I turned it off, restarted FF and turned it back on. I still lose all tabs every time I restart FF.

I only realized this is persistent now, after restarting on day 2 of this issue. My FF automatically updates.

Just now, I tried "about:sessionrestore" and it came up an empty list.

My FF automatically updates.
