I had to reload firefox after getting xpcom error messages, now i can't work out how to restore my passwords,bookmarks etc from my sync profile that i set up months before.

I have had a firefox account for the past 1 year I have browsed a lot of sites in that 1 year and had a few bookmarks too. I used to regularly sync the account too. Today after a normal browsing session I closed firefox. After I opened it up again it had automatically signed me out. When I signed back in, I saw that my whole history had been wiped, everything from the past 1 year. Now there is no trace of it. Please tell me what might have happened. Everything is gone. I can provide my account name and details. Please help

I have lost my profile in firefox, i have an account sync but after restarting my pc i lost everything and seems the profile is not existing and when i re log with my account i did not recover anything.

Please help me it is a big problem.

Thank you

My pc just did the latest update, the one with the new Logo. It wiped out all my bookmarks and passwords. I can reset the passwords, but I have hundreds of hours of research which was all bookmarked. I have changed laptops four times and each time I did, I would just sign into my Mozilla account and it was all downloaded into my new one.

Did anyone else experience this and were you successful in retrieving this data? Do you have any tips? This was important information on a health condition and I don't know if I can find all of this again.

Please, please help. I tried doing what I found in your forums but nothing helped. Could it be that the information was wiped out by your servers and it's permanently gone? I really need help. Thank you.

I wanted to open firefox and a new window for new firefox open but did not suggest me to sync my old bookmarks. instead it only asked me if i wanted to sync with chrome browser only. why was i not allowed to save old bookmarks before new firefox updated.

hi. i change my windows and now I need to restore my old setting and bookmark to new pc but i have not any backup file i was thinking my account save all of my data & setting in cloud but now i cant access to my setting and bookmarks

what can i do? pls help me

i have been using firefox for like an year, found out now that the email i used for my account on my browser is wrong, the domain has a typo. Does it mean that now all my passwords are saved on a firefox account i cant even access (i have to still finish the setup, obviously i cant as i cant get a code in an email that doesnt exist) and that i cant remove it, ever? Does firefox sync up stuff on an account without the setup even being done yet? Or is the stuff just saved locally and im good with removing the account?

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?

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 recently logged back in to my Firefox account that I hadn't logged into in about 3 to 4 months and all my passwords and links in the sync part are completely gone that took me years to setup. Is there any way of recovering them? Where did they do? I am positive I did not delete the account sync information. I would greatly appreciate any help in this matter.

I tried updating Firefox and it failed me. At the end of the day of work I did an automatic update. I shutdown my computer and the next day Firefox worked intermittently as in it would load pages and some it wouldn't load. I thought it was my internet connection and verified in another browser. The internet connection was okay, it was a Firefox issue. Then I notice the Firefox icon was a generic icon. I'm now lost all my bookmarks, which I thought I had in Firefox sync and open windows / tabs. This is a bit frustration that Firefox failed like this and caused me to lose data.

Today I find out that was logged out of my Firefox accounts. it happends few time this week. When I tried to log in, I found that all my passwords were gone. The logins-backup.json file is empty. after i restore firefox account synchronization happened and I'm afraid that I lost all my passwords. so What can i do?

So I reformatted my hard drive and everytime I finish I reinstall Firefox. I have an account where I log in and it put me back where I left off with all my past bookmarks that I saved. Ive been doing this for 10 years but today not sure whats going on but when I logged if all my stuff has disappeared. Please help or contact Mozilla regarding this. I cant understand why one cant directly speak to the ones who developed this browser. Quite frustrating

Hello, I recently used the option to sign out while also checking the box to delete data from the device. I was under the impression that once I had the new computer I could just sign into my account and my synced data would be there. This is not the case, because I can't even get my bookmarks and what not back on the device that I originally signed out of. I'm pretty sure I am on the right account so why is everything gone even though it said that synced data will not be deleted? Am I cooked? Losing all my keys and bookmarks is going to suck so if anyone could help me, that would be much appreciated.

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.

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.
