Hi, I’ve lost all of my saved passwords, bookmarks, and browsing history in Firefox. I’ve been a Firefox user for over five years, always tied to the same Firefox account email. My laptop recently had to be repaired, and the technicians performed a full reboot. After getting it back and reinstalling Firefox, all my data was gone. I tried recovering an old profile, but the reboot erased everything, so there are no old profiles or local data left on the device. Since my Firefox account has always been connected to the same email, I was hoping all of my data would still be recoverable, but I haven’t had any success. This represents over five years of saved information, and I really need help to restore it. Can Firefox support assist me in recovering my data through my account? Thanks in advance.

After Windows crashed, I installed a new system and logged into Firefox using my account. But all my history, passwords, bookmarks were erased. I also went to my phone and everything was gone. I didn't erase anything myself. Is there any way to restore the previous state of the account? Are there any backups on the Firefox Sync server?

I thought that synchronization would save my data so that I could prepare my PC for reinstalling Windows. As a result, after all the procedures and installing the Browser, synchronization does not restore my data. It's very disappointing. And the history of old sessions is completely erased.

I am thinking about trying sync now that I have both a Windows and Mac computer. Each has a different set of bookmarks, so let's just look at that.

I create an account. I set up sync on my PC. I then sign in on the MAC. What happens to bookmarks?

I would hope that the first time the PC bookmarks are made identical on the MAC. Then, regardless of which changes in the future, the additon or deletion or d=editng of a bookmark is echo's on the other device.

Is my thinking right? Can I force thePC to be the first accurate listing of bookmarks? And everything else I choose to sync?

Thanks.

So.... I ended up getting a new laptop and I signed in on my mozilla account and it turns out I have lost everysingle bookmarks/saved stuff / passwords etc....

Now... the thing is I do not have my old laptop anymore cause it doesn't even turn on.. I did not make a backup cause I thought all this information is saved online...

What do I do now to get my old stuff back???

Thank you

Hello, my computer crashed and needed a fresh install. I installed Firefox on a fresh drive, rest the password as I couldn't remember it on the first try (I now know what is but it's already reset) and it shows me 0 bookmarks, 0 saved passwords, 0 data and keeps reminding me to "finish setup" by importing bookmarks from another browser but my bookmarks were on Firefox.. After password change I was kicked out of my FF account on my phone so all the data is still intact on my phone. I haven't logged in my phone yet. How should I proceed to restore them on my pc and sync the to bookmarks from my phone and not the other way around?

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?

Hello, I just wiped windows and lost my bookmarks, passwords, and the like. I looked into the support options, as well Firefox profiles (about:profiles) but can't seem to get that data back. It's odd to me that it didn't sync because I also wiped windows last month and it recovered all of my data as soon as I signed into my Firefox account,so I was hoping that would happen again.

Any way to get this back?

Thank you.

I was signed out from my Firefox-Account on my PC for no apparent reason. I reset my Firefox Sync Password today and when I checked my saved passwords they were empty. In my profile folder there is a logins.json.corrupt file which probably contains all my saved passwords. How can I recover them and why doesn't Firefox sync them back like it's supposed to?

Thank you.

Hi, I just switched laptop< I no longer have my old one. I thought I'd just have log in to Firefox to recover all my information, like bookmarks and saved passwords, but now that I'm logged in, I can't find any of that. Is it possible I didn't save it? Can you help me recover it?

Thanks in advance.

Hi, I want to move my FF profile(bookmarks, passwords, login in's, CC info, preferences, etc) from my old computer to my new computer. I did a quick google search and found all I have to do is it copy the Appdata/roaming/mozilla/profile directory to the new computer. I had closed FF on the old system before I copied it to a USB drive. On the new computer I installed FF. opened it, closed it, copied the file/directory to the new system. There were already to profile subdirectories present. I just added mine. Now FF crashes. I can't have both computers on at the same time so I do not think 'Sync' will work. What did I do wrong? Any help would be appreciated.

So recently I had reinstalled windows and reformated all my drives, I am also sure that this account is my only firefox account. But when i checked the sync data it shows only 1 sync data which is today 14/3/2025. I am also sure that I had left all my sync data as default therefore it should have automatically sync. But currently I do not have access to my bookmarks, etc

I am having trouble logging into my bank account. Message is saying error, secure connection failed. An error occurred during a connection to online.newcastlepermanent.com.au. PR_CONNECT_RESET_ERROR. Have not had problems before. Please help.

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.
