My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

I used to have an account with everything on it

I restarted my computer and now I cant access anything from my old account. I used my same email account as before. what do I do I lost eveything

Hello,

Several passwords were saved by Firefox. They are only saved locally ( no sync with Mozilla account). I recently upgraded my laptop from Windows 10 to Windows 11. Since the upgrade, no password is available in "Saved Password" section. I checked my profile and I can find logins.json file ( with all encypted logins and passwords) and key4.db file. I suppose my passwords cannot be decrypted as they were encrypted with Windows 10.

Is there a way to recover my passwords?

Can Firefox do anything to recover all of the downloads I'd saved until I accidentally had CCleaner erase everything? I don't know what else was deleted, but getting them back would be a big help.

So Firefox just wiped my cookies, my tabs, including my tab groups, and my settings in both about:preferences and about:config after an update. My history, passwords, and extensions are still intact, so it was not a true refresh. I can deal with the settings and cookies again, but my tab groups are nigh-unrecoverable. "Recently closed window" is greyed out, so that did not help either.

In the "Add Tab to Group -> Closed Groups", my old tab groups are still listed, but as far as I am aware there isn't support to access them yet.

I checked the root profile folder and, following the instructions from this thread, managed to fetch my tab groups from previous.jsonlz4 and recovery.jsonlz4.However, I could not for the life of me get mozlz4 to launch.

Additionally, I have an older backup of the same profile from 2 weeks earlier. This backup also confirms there was some unspecified data wipe, since it is 2GB more than the current profile folder.

With the available recovery data at hand, I have a couple of outcomes that I can live with.

1. I can indiscriminately replace my current profile with the old backup and hope that when I restart Firefox will correct itself to match the current version.
2. Someone could help/instruct me on which files to pinpoint to recover my site data/cookies/tab groups discriminately from all the files in the backup, so I don't have to fully replace the current profile.
3. Someone could help me troubleshoot the guide outlined in the link above to figure out why mozlz4 is not working.

This has been driving me nuts over the past 24 hours and I honestly do feel like I'm a bit out of my depths. Any help is appreciated.

Getting ready to replace my computer. Is there a way to take my Firefox bookmarks and passwords along with me. I know there are 2 profiles in different directories.

c:\users\jer\appdata\roaming\mozilla\firefox\profiles AND c:\users\jer\appdata\local\mozilla\firefox\profiles

Don't really know difference between roaming and local, except roaming is a lot bigger.

I doubt I could copy the whole profiles as they would contain information that is about current computer and wouldn't work on new computer. However, it seems that I have read or seen there are files within these profiles that just contain my bookmarks and passwords and they can be moved to another profile.

I just need to know the name of the files that hold his information.

Any help would be appreciated.

My SSD boot drive crashed -- Rebuilt system (brand new SSD boot drive) and reloaded all of my data from a separate backup, however Firefox profile is gone. I have copies of the old profiles including the places files, etc. Following Mozilla's instructions I reloaded the old profiles. Firefox starts right up but *without* my bookmarks, etc. Unfortunately there was no "old Firefox data" folder saved and I could not retrieve the bookmark specific backup. Thoughts? Thanks!

I restarted Firefox and noticed my toolbar book marks were missing. In further inspection, I noticed all my bookmarks over many years are missing. This is obviously a disaster. What happened? Is there way to recover this information?

Today my Firefox browser updated & all my bookmarks have disappeared. In place of my Bookmark toolbar is just "For quick access, placeyour bookmarks here on the bookmarks toolbar. Manage bookmarks(link). The bookmarks side bar is empty. I've followed the instructions to try to recover them but the page(Goes there from the "Manage Bookmarks" link) they send me to has no functionality. Whatever I enter goes nowhere, whatever I select. I've tried several different routes from the support/help pages to resolve but always end up at this dumb page. See here(https://www.dropbox.com/scl/fi/fop0kf0qb2nu442pqc6jz/Screenshot-2025-05-14-17.13.28.png?rlkey=3x1pchkfxq12whipytzzkte2x&dl=0)

How do I get my bookmarks back when the tools to do so don't seem to want to work?

Some of my shortcuts were missing on Firefox when I started my laptop this morning. I tried restarting my computer but that didn't help. I really don't know what topic fits best. I am not at all tech savvy when it come to computers.

My Bookmarks are missing. I see backups under the profile/bookmarkbackups folder but when I manage bookmarks, they are not in the restore dropdown. I have followed the steps to delete the places.sqlite but when I reopen firefox, I do not see the bookmarks have been restored. I thought it might have been related to Norton Utilities so I renewed a subscription but no luck. I also have a json file with my bookmarks but I cannot choose it from Manage Bookmarks, either

Today I opened Mozilla at my laptop. It malfunctioned (videos froze, pages did not fully download), so I closed the window and after a couple of seconds I reopened it. My previous session was gone. I read your articles regarding this issue, did what was described there, but nothing has changes. I lost everything! Job videos, hobby pages - everything! A couple of pages can be restored via history, but that's it! I didn't do anything special before closing the window!

I power cycled my computer in order to install some Windows updates, and when I opened up Firefox again, I had precisely zero bookmarks.

I found this folder, which is supposed to contain my automatic backups: https://i.postimg.cc/bwrWBswd/A.png

But I can't figure out how to use those files to restore my bookmarks.

When I click on Manage Bookmarks > Import and Backup > Restore > Choose File, nothing happens. No other option seems viable.

I had an ASSLOAD of bookmarks on this browser, so I need to recover them because there's just no way I'll be able to remember them all manually and add them all back one at a time!

What do I do?

I've been backing up my opened tabs for the past 4 or 5 years with the steps in this legendary post: https://support.mozilla.org/en-US/questions/1257866

But this time it failed me and I don't know why. I just switched from Debian to Linux Mint, put everything up to date, but when I copy the sessions-store folder back into my session folder, as described in the post, nothing happens. I tried restoring only the 2 files listed there, and also dropping them in the general user folder, outside sessions-store, but still nothing. I've also noticed that the sessions-store folder isn't created automatically, even if I open a bunch of new tabs now and close the browser.

I don't even know how to begin troubleshooting this to be honest, this is the first time this method's ever failed me :(

I also saw this post: https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup But it doesn't help either.

I ran into a glitch in another program, and as part of trying to fix it I rebooted my computer. On doing so, I find that the VAST majority of the tabs I had open in my main browsing window have disappeared - some of them out of tab groups I'd created to avoid losing the tabs in question. Neither tab history nor browser history show the missing tabs.

What gives?! Is there any way to restore the window as I had it, say, yesterday?

When I opened Firefox, all my profile settings were back to a Default. Lost all my settings. Looked up solution on Google, couldn't find an "Old Firefox Data Folder" anywhere.

Tried the other listed "profiles" in my profiles folder, none were my most recent profile with all my settings from the past months.

How can I find the profile that was used before my update which was done 7/27/25 ish.

not all windows appear in the drop down "window" menu, and a different number when each window is on top. Weird.

Using Mac OSX. Nothing is "full screen." Seems to be nothing to do with if a window is minimized or not.

I have restarted. Recently updated, and lost profile, but recovered it, but lost all my open windows & tabs, so now I have only 5 windows open. Seems to be nothing to do with if a window is minimized (OSX) or not. Needs a better mechanism to save open windows & tabs along with profile data.
