Hello Mozilla Support,

I am seeking assistance with recovering my Firefox data after resetting my laptop.

Before performing the reset, I verified that I was signed into my Firefox account and believed that Firefox Sync was enabled. After reinstalling Firefox and signing back into the same account, my previous data does not appear to be available.

Being a weird person, I always saved my sites on my firefox browser and for my own reasons, hadn't bookmarked them and always kept them open on tabs to pick up and read at a later date, and as a result, racked up a lot of different tabs that were all very dear to me. However due to a catastrophic hardware failure a few hours ago I lost everything on my local files, including my backups of all the firefox tabs. I was hoping that if there was a remote possiblility that if the sync was able to record tabs, that it would also save all tab information from previous browser sessions.

Hey hey So On my old system I logged into my FF account did 7 syncs just in case whi all were telling that I'll have all of my stuff right away but.... I reinstalled Windows and... installed Firefox and got freaking 00000000 zeeeero tabs or passwords synced.... All of the manual attemps of sync got nothing, absolutely nothing!? So what was the point of online account which does nothing and just give a fake faith??? I would rather do cp -r of local foler as I did for the last 20 years.... But this time I was faked with fake "sync all good" which doesn't work and just fake people

I had experienced the dreaded "XPCom error" and had to do a clean reinstall of Firefox (I know, I should've followed the rule of saving anything important in 3 separate locations.) I had re-logged in and noticed I didn't have any of my bookmarks or anything. Am I out of completely out of luck in this case of trying to get anything back?

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.

Firefox has exceeded all previous mess-ups by upgrading itself today (apparently sometime when my battery went flat and was then left recharging), and this happened despite my account being set for 'upgrades to be only installed manually'. Now every bookmark, all passwords and all the settings of my Home Page have been erased. I have no 'restore point' to resort to as supposedly all this info is synced to the cloud. But I can find no method to retrieve any of these files let alone one to restore them. This is a nightmare. Please help.

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 ????

for context: my laptop was working/running completely fine last night, as of about midnight (east coast). booted it up around noon today to see that it was super slow and kinda laggy (this is a windows problem, not a firefox one, don't try and fix that, i know it sucks), and that if i restarted/shut down, it would automatically update (not what i wanted). when i did finally begrudgingly restart my laptop, it auto-updated as windows does, and i expected to open up firefox and go on with my day.

unfortunately, it prompted me to make a new user. and when i signed into my firefox account, it treated the browser that i have used for at least 8 months like i had freshly downloaded it. all of my history on here is gone. all of my bookmarks are gone. when i connected my phone to try and sync from what i had left before i updated, all my sync information went down the drain and is completely gone as well. i really don't understand what went wrong here, and i'm honestly devastated that all of my work and my history has to be painstakingly rebuilt.

if anyone has any idea of what happened here, it'd make me feel a little better and try to avoid it in the future.

Hello,

My personal toolbar and all my bookmarks were saved to my account at [email removed]@u-bordeaux.fr, and today at 11 a.m. I lost everything. I can't seem to recover these bookmarks; I think there was a synchronization issue. Can you help me recover what was lost? Best regards, Jonathan

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

My computer crashed and after restarting I have lost my account data including profiles, history, bookmarks, extensions, open tabs, etc.

I have tried the basic methods suggested online like looking for hidden profiles, finding a folder for old Firefox data on the desktop, restoring from apparent backups that are meant to be there, etc. The account should have been logged in all this time and had sync on, which is not working... but should there be some sort of sync history I can restore from? Or a local backup from somewhat recently?

Thank you

Not sure how to proceed to get my bookmarks moved from my old laptop to my new one. I'm a mainframe guy and often get lost with these PCs. :-)

Thanks...

I lost ALL of my passwords, saved favorites and am so pissed with my inability to retrieve them. I occurred when I was in the sync settings while personalizing firefox. What gives?

My computer unexpectedly had to do a factory reset. I had to add Firefox back on to my computer. It was my main default browser. I couldn't remember my password because I had Firefox for so many years. Your system forced me to change my password and now I cannot gain access to my bookmarks/passwords when I sign on. If you tell me that those were lost in the transition, I will be so upset. This was the only reason I was using you and do not understand why syncing is not working or recovering the information. I hope that this can be recovered, if not I have no use for your browser and will switch to a more updated browser in Chrome. I have never had such problems and cannot even remember all the bookmarks I have lost. I will never forget this experience. My hope is it will be because someone there was able to save the day and not because I realized that your company is outdated and clunky like Microsoft. Hoping you can help and completely upset. I am also very confused why my information would not have backed up automatically.

I have a rather strange problem and I'm not sure this is the right topic. I generally use my computer on and off all day and I never lock it until the evening when I turn it off. I went out for several hours today and when I came back there was a new version of Firefox installed. When I opened Firefox I realized it was a new version because it would not let me logon until I had completed a profile. My old version never did this. In addition all of my saved passwords had disappeared as well as my bookmarks. I'm using a Dell laptop running Win 11, about 2 years old. I don't understand how this could happen. There was no one here while I was out. I looked to see if there was a saved profile but only the one in use showed up. The current version appears to be 145.0.1. One thing that might have something to do with it. I might have been asked yesterday if I wanted to synch firefox on my computers but I'm not sure how I answered this (I'm almost 90 and my memory is a bit imperfect).

I do have Firefox on a second desktop which is running Win 10. Is it possible to use that profile. That computer has not been turned on since this happebd and is currently asleep. Any help or suggestions will really be appreciated!

All my firefox bookmarks disappeared on my desktop even tho' logged. Still on phone and laptop. How do I sync so I get them back and not erase the two mobile devices?

Hello, after changing devices, I had to change my Mozilla password because I could not access my password manager at the time. When syncing, I realised everything had disappeared. I still have the old password, have changed it back to the old password, is there anyway for me to get my data, I have no copy of my bookmarks or history or anything?
