Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

Hello, Hi I recently updated (last night) and i didnt check all the boxes i clicked skip but NOW i can not recover any of the stuff from the night before is there a way u could help me ?!

Help, My computer performed an automatic update, rebooting itself and all the history on Firefox has been lost all my open tabs have disappear. I followed other instructions to open the Profile Folder, but the only 2 files there are the ones created after the reboot. There are no previous files. Thanks, Juan

In my Win 10 PC, Firefox has been set to update automatically as it is recommended.

136.0.2 (64-bit) is the most recent one that updated automatically.

Now all my extensions have been wiped out, my workspace changed.

That is such a breach of integrity, and a lack of respect for the user, and his carefully set up work environment, when an Auto-Update just molests my work environment. And then I have to take out hours from my busy routines, to devote to restoring everything to how it was.

There is no rollback feature for Updates, esp when Updates do the havoc they do.

There is no proper Session Management, and a standard protocol for saving, aggregating sessions across different installs, rollbacks, etc, and having the most updated, and complete one, where the onus is on the user not losing data.

Now I have to go hunt around for the past profiles, and name the present one as old, and hope that Firefox functions with integrity, and completeness to restore my whole work environment from the last profile. I'll of course be losing whatever work I happened to do in the new profile now. One never knows how complete these profiles are to reconstruct things exactly the way they were.

Strange. I always believe that stability, and integrity, and a dedication towards that on behalf of the user would be the primary goal. Now it's all about chasing something else, some bells and whistles, and faster performances, and throwing stability, and data integrity under the bus.

Installed 134.0.2. Bookmarks disappeared. Went to restore backups, receive message "unable to process the backup file". All of my bookmark backup files receive this message when I try to restore.

I had to replace my motherboard and the new one would not boot from my old D-drive. I've been carrying my world forward since 1993 and am retired and so I figured it might be a good time to start over, just bringing the stuff I still need or want. (I have data disks for non-program related stuff, so that part is easy.) I've carried my FireFox profile and tabs from one installation to another before, so I didn't figure it would be a problem. Wrong.

I have copied my old profile into the new FireFox installation on the fresh new install of Windows 11 and everything came just fine - except I cannot recover my old tabs. There is supposed to be a Restore Tabs or Recover Tabs or some such selection in the History menu, but it is not there. It is not in the history library. It is not anywhere to be found.

So how do I restore my old tabs?

Thanks,

Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

Firefox updated to version 137.0 (64-bit) on 4/1/2025 and deleted all of my Favorites. I tried to restore them from Manage Bookmarks - Import and Backup - Restore - Choose File. Choose file does nothing. I restarted the Windows 11 PC with no change and deleted my Extensions.

Придется вам как-то перевести самостоятельно то что написала на английский. Зачем писать что при обновлении все будет сохранено, если после обновления, половина окон на восстановилась и история предыдущих посещений пропала.? и как мне теперь все это восстановить обратно?'

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Moved to different pc, logged into my account, all bookmarks gone. What is going on? The sync even synced with empty bookmarks, and I guess everything I bookmarked is gone now.

Last week I deleted browser data & cookies (for a Microsoft account I use) & then I accidentally used an incorrect password to login to Facebook & they locked my account. When I tried to change my password they didn't recognize my device, which I've been using for MANY years. They also reject photos of my i.d. & won't tell me why because I'm apparently trying to communicate with an a.i. bot, NOT a human being. P.S. To make things even worse, I was locked out of my phone, which kept asking me for a password that I've NEVER set up. So I had to do a factory reset & lost ALL my data.

I've tried everything I can think of & I'm wondering if it's possible to get at least some of the data back?

I had a issue with my Dell laptop, when it was resolved It had deleted Firefox. They created a new one, but the bookmarks are gone. I have looked at the information on recovering Bookmarks, but still cannot recover my bookmarks.

Can I get help on this issue?

Thanks,

Riley
