""What happened:"" Yesterday I updated Firefox to 151 and noticed a "Profile" feature for the first time. I created a new profile, then saw a small icon with the Firefox icon that bothered me and realized it belonged to the new profile. I thought that the newly created profile is safe to delete and has to data within, so I deleted it. After that, Firefox deleted all old data and created another new profile and I lost old bookmarks, passwords, and browsing history.

Note: no warning was showed before deleting the profile.

What I tried: 1. Checked about:profiles profiles: no old data. 2. Opened the profiles folder in C:\Users\[my account]\AppData\Roaming\Mozilla\Firefox\Profiles: no old data found. I noticed one of the default profiles contains a places.sqlite file that’s about 2 years old: no old data, only default bookmarks are there. 3. Used Recuva to try to recover files — I recovered key4.db, login.db, and places.sqlite-shm but nothing useful so far. Environment/details: • Firefox version: 151 • OS: Windows 11 • No Firefox account Questions: • Is there any way to restore the old profile data from the files I recovered (key4.db, logins.json/login.db, places.sqlite-shm)? • Any other recovery steps I should try? • how to prevent the same thing in the future? Thanks

All but 2 of my previous saved windows have been lost. They are not recoverable or present when trying to use "Recently closed windows." How could this happen? More importantly, how can I recover them? They contain numerous tabs that will be impossible to recreate from memory.

Dear Mozilla // Firefox persons - you really know how to shoot yourself in the foot.... I am fed up having lost all bookmarks and not able to initiate anew despite intolerable checks for updates, restarts & reinstalls. Really pissed me off. Your "help" pages are grossly overpopulated with waffle and dead end links.

I got logged out of my Firefox account and upon logging in a bunch of dummy "sync" data replaced all of my bookmarks, settings, ect. Is there any way to undo this?

Hello,

I hope you're doing well. Unfortunately, my Firefox account was still signed in on my old mobile phone, which is now being used by my father. He accidentally deleted all of my bookmarks, and I have completely lost access to them. To make matters worse, I do not have any offline backup of my bookmarks.

I was wondering if there is any way for your team to restore the bookmarks associated with my account to a state from before December 31.

Thank you very much for your time and assistance.

How can I Recover Deleted Firefox (build 151.0.2 (64-bit) Browsing History in my version/edition of Windows 11 Pro, Version = 25H2, installed = 12/06/2024, OS Build = 26200.8524. Can you help me recover my Browsing History from Friday, 05/29/2026? Please.

Hallo,

ich hatte bereits Anfang des Jahres beim Einrichten meines Laptops Probleme damit, meine Lesezeichen wiederherzustellen. Damals habe ich es jedoch mithilfe eines älteren Profils geschafft.

Nun musste ich den Laptop neu aufsetzen und finde die passende Sicherungsdatei der Lesezeichen nicht mehr. Ich wollte die Lesezeichen daher wieder wie gewohnt zurückholen. Leider gibt es jedoch kein älteres Profil als 24 Stunden. Das bedeutet, dass alle Lesezeichen verschwunden sind.

Gibt es eine Möglichkeit, auf ein Profil zuzugreifen, das ein oder zwei Wochen oder sogar vier Monate alt ist? Und vor allem wie komm ich da ran?

Hello,

I recently reinstalled Windows on my computer, and after setting everything up again, I noticed that all of my Firefox bookmarks are missing.

I would like to know if it is possible to recover or restore my bookmarks. Before reinstalling Windows, I was using Firefox normally and had a large collection of saved bookmarks. Unfortunately, I can no longer find them after the reinstall.

Could you please let me know if there is any way to recover them, either from my Firefox account, a backup, or any other method?

Thank you for your help.

I'm sorry to say all my groups and tabs were not opened this morning, and the restore session option doesn't even show up in options!

The groups are not even in my history even though I used them yesterday!

How can this be?

I don't believe they're all gone. I know sessions are backed up...

Please help

thanks

MacOS Sequoia 15.7.7; Firefox 141.0.2

The "one sentence" in the heading states the problem. I am unable to use Firefox. Using Safari to make this post.

Firefox loads. It opens windows (I had fourteen open when I last used it successfully; I have many, many tabs). Then it removes each window from the screen. Firefox is in the Menu bar, but no windows are displayed. The windows still show in the list when selecting Window in the menu bar. Selecting a window in that list has no visible effect. File>New Window opens a new window, which works as expected. With one new window open, File>New Window opens a second.

Typing a few characters in the address bar opens a dropdown with a list of tabs, each with the affordance, Switch to Tab. Clicking on one takes down the list but does not open a window.

I would like, for a start, instructions on how to use Firefox starting afresh with no windows. First: having set aside the data that causes this problem. I suppose that might be simply a new profile. But would like instructions from a person interested in pursuing the problem with me while I continue with the rest of my life.

I'm willing to delete some data from the failing profile, is there is reason to do that, but would like to preserve at least a list of the URLs of the tabs of the windows. Or to learn how to see those in the profile data.

I see four profiles:

  <garble>.default-<13 digit integer>  Date Modified: Today  2.2 GB
  <garble>.Default Profile   Date Modified: Last June   24.6 MB
  <garble>.default-release-1   Date Modified: Last June, five minutes later  93.2 MB
  <shorter garble>.default-release   Date Modified: 2021   13.4 MB

Thanks in advance.

The entire browser was acting extremely slowly, on every website, every start up. It crashed constantly to the point it was unusuable, it was even affecting the performance of the rest of my pc so I reset it and everything I had on the browser disappeared. Bookmarks, passwords, etc. I've tried going through the profile support pages but only the profile made from the reset exists. I had years worth of important bookmarks and passwords that'd I'd like to be able to get back if that's at all possible. (I'll live without them, it'll just suck trying to remember them all again) PC is Acer Aspire 3 Spin 14, Windows 10

How can I prevent firefox from DELETING all my bookmarks EVER AGAIN! FUCK!!!!! They did some kind of screwy update and reverted my bookmarks back by 6 months and I can't get them back. And yes, I saw all the backups they "stored" but they are not in there.

Hello! Is it possible to recover older open tabs from a broken device that had sync activated? For a while they appeared in the hamburger menu in the top right, but now they suddenly disappeared, and under the "connected devices" I cannot click the device or anything. It went broken 2-3 months ago. Best wishes!
