I last sync my data on 31, August,2025 and delete all password from the device now I only have my passwords and bookmarks etc all data sync to Firefox account. And today I tried to login back to get my passwords, I forgot the Firefox account password and reset the password by clicking on forgot password and reset my account password. But my all synchronized data , passwords, filling forms, bookmarks all gone and I had nothing left. Kindly give me my data and passwords back and if you need any verification from me that it's original me person. Kindly cleanse give me a backup of password as I really need them. My all PhD thesis , all data there and I didn't remember any passwords. What to do now. I am very much depressed please help me out

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

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

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?

i deleted the document file in drive c and the app data by mistake, Im sure the syn was on for more than i can remember and even a few days ago i did the syn again, after the reboot i signed in and did the syn ,there was nothing at all please help me

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,

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 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 phone broke down and I had to send it in, for it to be repaired. As usual for warranty repairs the phone needed a factory reset to be sent in. Before doing that I backed up my session using Firefox sync as described here: https://support.mozilla.org/en-US/products/mobile/backup-recovery-and-sync/backup-data That went fine and I could access the data from my PC.

Now my phone returned, I reinstalled firefox yesterday and immediately after signing in, my backup in Sync was overwritten with a blank session. Is there any way to get the old session back?

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.

Фаер фокс обновился после какойто ошибки и я потерял доступ к папке олд дата могу я както вернуть с помощью своего аккаунта все кладки. Может они храняться как в базе или отправить мне прошлый профиль еще раз?

my phone and windows 7 desktop both sync bookmarks on Firefox. The PC got corrupted and had to be reinstalled. I reinstalled it without bookmarks and went to my phone to sync bookmarks before adding backup bookmarks to the desktop Firefox. That wiped out my phone's bookmarks. how can I avoid this next time.

My firefox recently crashed (f5ea38ba-f4f8-4224-8ab8-982e19cc72f7) is the crash code if that helps it happened just now, i dont have any additional profiles and no folder such as "old firefox" is there any way i can recover all the information and my old settings or passwords or anything? I tried to log into my firefox account to sync up data but there was no update on the information

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.

On Firefox browser, I cannot Copy a file in Studio Code Server (within Home Assistant). SCS is open in HA in a Firefox tab. I get the error popup "Unable to read from the browser's clipboard. Please make sure you have granted access for this website to read from the clipboard." "Learn More" links to https://code.visualstudio.com/docs/remote/codespaces#_how-do-i-allow-vs-code-to-access-my-clipboard-for-reading and the "How do I allow VS Code to access my clipboard for reading?" section. But I cannot find similar settings in Firefox's Settings menu.

Any suggestions please on how to resolve this? I'm sure I used ~ a year back to be able to Copy a file ok in VSCode on Firefox. Thank you.
