The title sums it up. • Does anyone know why FFx , when opened following my MacBook Pro Restart, opens without any of my selected Tabs AND then provides no History of my last FFx session??? • Hours of Internet research, vanishes! It really p--- me off! • This has happened at least 4 or 5 times in the past year to year and a half and on both computers. And I do stay on top of my FFx updates. If a Notice appears on my screen, I usually install within 24 hours. • This last time (today) I had previously updated FFx a few hours earlier and then I needed to run a Restart of the computer.... • MBPro fires back up, I open FFx and nothing in the Tabs Header. GONE! Poof! • I go to Browsing History - no Restore Previous Session (by any other term) • Doesn't it seem logical? THAT fundamental function would be right there, top of the list?!?! • HERE IS THE KICKER: In FFx I opened the FFx "About Firefox" menu and noticed it says, amidst all the provided information, "Failed to check for updates." • BS! It was following the update that FFx Tabs vanished! How can it insert that statement? Was I suppose to do something other than click "OKAY". And then the new version begins when FFx is reopened. Right? • If this comes down to the older OS on the computer (10.13.6) I should not be receiving update notices from FFx. If so, a notice of, "Your Mac's OS is too old to run FireFox's latest version" would be what I should receive. So, as you can tell, I'm frustrated and baffled at the same time. Any thoughts? I would appreciate it. Thanks

Hello Mozilla Support, I enabled Settings → General→ Open previous windows and tabs, but after restarting Firefox all of my tabs were unexpectedly lost. I’ve confirmed the setting is still enabled, restarted Firefox and PC and checked History → Recently Closed tab with no luck. Why wasn’t my session restored? How can I recover my lost tabs? How do I ensure Firefox reliably restores my tabs going forward?

My husband was trying to fix an Outlook account that was damaged because of a power outage and in the process reset some of my accounts. I couldn't log in to Firefox so I used my email and hit reset password. In the process it said my account was new as of June 25, 2025 and I lost all my passwords saved in Firefox. This is a desktop computer with Windows 7. I have a new computer with Windows 11 and it still listed my passwords but said my account was disconnected. I don't know how to keep my passwords in that account but don't know how to access them so I don't lose the information.
