Restarted my browser to update, and it 1. crashed my computer, and 2. erased all of my bookmarks and previous information. When I tried to log back in, it said that I couldn't restore anything and that I didn't have an account with my information already attached, even though I've been using FireFox and have saved bookmarks for years. How do I get it back? I know it exists somewhere, so I don't understand why I can't find it in the app now. It doesn't make any sense why it would seemingly crash my computer, too. Please help.

I had some issues with Firefox so I removed and I reinstalled it. I had a Firefox account with sync enabled on since one year ago. However after the update, I couldn't recover my old profile: my bookmarks are gone. I don't know what to do. None of the guides were helpful. With an account and sync on, should have been enough to restore my data, right?

I just reinstalled my OS (Windows 11), and installed Firefox, logged in, and just couldn't believe my eyes. Everything is just gone. Passwords, history, everything. Why then Firefox Sync is using email and password if it doesn't have any cloud storage for passwords and doesn't even work like chrome? Should I install Firefox on my iPhone to regularly sync two devices (manually), to store passwords on another device, then sync back?

Mir ist mein Computer abgestürzt , musste ihn neu aufsetzen . Nach der installation von W11 25H2 , neueste Firefox 64bit installiert und versucht Lesezeichen und Passwörter zu syncronisieren OHNE ERFOLG alles WEG WIESO ????

j'ai restaure w11 en supprimant tous les fichiers, puis mise a jour mon compte mozilla qui avait 2comptes 1 perso et 1 pro, pour mettre a jour a 1 compte par session pro et perso et éviter confusions ,j'ai certainement fait une mauvaise manip et je ne retrouve pas mes marques pages et mon organisation . puis je retrouver ces marques pages ???? en me reconnectant a mon compte initial et resynchroniser pour info le mot de passe du COMPTE PRINCIPAL MOZILLA a été changé car les 2 dossiers qu'il incluait avaient la même adresse mail . pour faire simple :

COMPTE PRINCIPAL MOZILLA  : cccc adresse gmail mdp : xxxx123

dessous  : compte PRO  : cccc adresse gmail mdp : xxxx123

dessous  : compte perso  : JJJJ adresse gmail

je pense avoir tt essaye , vu que j'ai restaure w11 et supprime les fichiers je n'ai plus l'anteriorité , le fait que j'ai change le mot de passe du COMPTE PRICIPAL DE MOZILLA a du ecraser les donnes . qu'en pensez vous avec mes remarciements

Firefox has reset entirely.

All of my profiles, bookmarks and saved passwords have disappeared; only history from this session appears. When I look at "Sync" I see the tabs from one of the profiles in the "Tabs from other devices"... it looks like Firefox thinks I have signed in from a new device, but I haven't.

The "tabs from other devices" lists the tabs from one profile under the correct device name. I am hoping all of the profiles, bookmarks, passwords etc are in there still. How do I "reclaim" these profiles on my laptop?

Where is this information stored so that I can access it?

Firefox keeps forgetting my bookmarks, so I uninstalled and reinstalled Firefox. After reinstalling, Firefox defaulted to my wife's profile. I then tried to recover an old backed up profile using sync. I selected the right profile, but Firefox reports there are no compatible files in any of several backup file folders.

Quite simply I replaced the dead power supply on an old PC of mine and booted it up to start using it again as a work PC.

When I did the now decade old version on firefox told me I might want a clean reboot which I clicked Ok since the history was so old on it as to be irrelevant. Firefox closed but didn't reboot. So I launched it again and simply chose not to restore the old tabs when prompted (not even some of them as that was also an option). I updated the old version on firefox I had on it before restarting it and logging into my firefox account to sync and try to transfer my work tabs to the old PC. When I did so I realized on the old PC that reopening Firefox didn't reopen where I had left off. I thought it was just the update but did a check nonetheless. Opening a couple of random tabs before exiting firefox and launching it again. It didn't reopen the last tabs. I checked the settings: "open previous windows and tabs" was checked. Did a brief google search that confirmed my next step: uncheck that box > exit firefox > launch firefox > check the box again > relaunch firefox. I did all that and was still not getting my tabs back.

Then I went back to my current PC (where I had changed nothing) and missclicked (I think I was going to the settings) exiting firefox there (3 windows and probably ~60 tabs ... yes I have a problem). And now even on my main PC firefox didn't restore windows and tabs!

I hoped I could go to history > reopen closed windows but no dice. The option is greyed out. That is also when I noticed I had no history whatsoever.

Now I unfortunately relaunched firefox a couple of times here trying to troubleshoot BEFORE I went online and saw that I could have possibly restored the last session using some backups.

With all that in mind can I still restore my tabs/history somehow? And why isn't firefox picking up where I leave it even though the option for it is on?

All of this is on firefox v148.0 on win10 for both PCs if that's relevant.

Thx in advance for any and all help!

A power surge took out my computer during a Windows up date, I could not recover anything, so did a fresh install of Windows........now, I can't get Firefox to bring over my bookmarks. I am so upset and lost right now, I'm sure I'm just missing something to do. Please help.

To whom it may concern,

After the latest update I was met with a blank profile, no saved data, even when syncing with my Mozilla Account. I followed the back-up instructions by the support team described in the forums, but it wasn't enough. Common sites I frequent like youtube and gmail were not indexed, the passwords and logins were nowhere to be found. I really don't get what's going on, or why would the Mozilla Account wouldn't recover the data, while leaving that to profiles. Is there any way to recover it further? Or even disable profiles?

Thanks in Advance,

Hello,

I am contacting you because I have a colleague who lost all her bookmarks when migrating her Mac computer. She was syncing with her Professional account. When she migrated and used her account to recover her bookmarks, no data came back. Her laptop was wiped and then reinstalled, so it is not possible to recover any data from it.

Would it be possible for you to find his bookmarks?

Thank you for your help.

Best regards,

Frederic Migaud

Dear Firefox Support Team,

I am writing to urgently request your assistance regarding a critical data loss issue with my Firefox account.

Recently, I reset my Firefox account password because I could not remember the original one. However, I was not informed or clearly notified during the reset process that resetting my password without a recovery key would result in the permanent loss of my synced data, including saved bookmarks, passwords, and other browser data.

Unfortunately, this Firefox account was the only place where I had stored this important information, and I had no separate backup of the data elsewhere. I understand that for security and encryption reasons, data cannot always be recovered—but I believe users should be more explicitly warned during the password reset process.

I had to reinstall my operating system, and thought the Sync with the passkey would allow me to recover my saved passwords and bookmarks. But I put in the key I was given and nothing was recovered. Did I completely misunderstand how the Sync was supposed to work?

I had sync turned on before I reinstalled my OS, and now I have lost everything. Is there anyway to recover the stuff that should be there? Yes or no. If yes please provide steps, and not the self help articles here as they are worthless.

I know the system backs up bookmarks every day or so. I want to migrate all to a new PC. With a new Laptop it seems to have done so automatically, maybe through synchronize feature, I am not sure how I did that . I normally export bookmarks to a external flash drive as HTML. Just did also to a .json file type cannot find how to do that. Which format and method will be best? Have all of the old PC backed up through Acronis full back up. Will that have the full Firefox program with the bookmarks?

You jerks deleted passwords and bookmarks I needed for work just because I reset my password to login. Why in gods name would you think that's a good idea? Why would I ever use your sync function if you're gonna delete my data the moment you get the chance?
