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 was using my account for sync my bookmarks, but i hope that was saved in my phone. After check CCleaner deleted all from my laptop, i realize that was also deleted from my mobile. ¿How i can recover all my bookmarks that was sync in my account?

Hello there. I had to recently wipe my computer on 4/12/2025. I forgot to sync my bookmarks and passwords. Is there any way I can possibly get these back? I don't know how far back Mozilla itself keeps files, I've been told they do but I'm not sure how far back.

Firefox keeps stopping on my Android; in fact, it won't even load. I have tried clearing the cache and clearing the storage, but that has not solved the problem. If I uninstall and reinstall Firefox, is there a way I can save my bookmarks? I don't think I am currently signed into (or registered for) Firefox Sync. I am hoping it might be possible to do that from my laptop. The bottom line is I really don't want to lose my bookmarks if at all possible. Thank you for any help/ guidance

My primary PC died about a month ago, and the SSD is fried. I had it synced to both my phone and a secondary one, so no problem accessing things. I bought a new one online, and it just arrived. Then, when I tried opening all my tabs on my new PC, I found that they were no longer available, on either that one, or my other devices. This is new, because I had already recovered a few individual tabs to my phone previously, but I hadn't thought to open all 50-100 of them then since I was waiting on a new primary laptop. The device still shows up among the connected services on my account, but it doesn't show the tabs anywhere I could find, and since the SSD doesn't work I can't go into the files and manually port them over. Is there a way to solve this?

I have always been logged into Firefox and I know that I had updated my bookmarks but recently I have re-installed my Windows and after logging into firefox all my bookmarks are gone. I don't have a html file and I can't 'upload' them manually.

I was hoping that they would be automatically updated after sign in... All I have are default bookmarks and the last 'sync' is showing today, which is after I re-installed Windows... Is there any way to get them back?

Any advice?

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.

Hey I changed my password before reinstalling the Windows but when I reinstall Firefox and logged in, all of my information was gone since Firefox doesn't back up after password change so I uninstalled Firefox since then because it was useless to me. I was looking through my files and I find that I still have the previous recovery code before changing password, can it be used to recover my passwords and bookmarks?!

i reinstalled windows and re downloaded firfox i logged into my firfox account like a normaly doo to get all my data but non of my data is getting synced it always works but it is not working no i need my data i have my passwords to all my account on it pls help

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 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

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

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.

Hi, I had to reinstall my windows where I thought my Firefox would sync up upon reinstallation. However, nothing would sync up and the best I could do myself was to import pretty out-of-date Chrome data. When I to my firefox account and scroll to connected services I see my last PC name with its firefox login. Is there any way to recover that data and import to my current device? I read you kept sync data as encrypted data on your Mozilla servers, so I hope that's a viable solution.

I accidentally Uninstalled my Firefox(don't ask). So I reinstalled it. How do I get the info from my old installation into my new installation? I don't have the sign in info for my old installation as that where it was saved.

Hi, looking to ask if anyone has experience with restoring Firefox open tabs after closing them accidentally on Android.

Environment: Android 14 Firefox account sync enabled

Things tried: 1. Firefox Sync (The open tab information was promptly cleared away by the sync) 2. Open tab information from a separate desktop Firefox browser with Sync enabled prior (same issue as #1) 3. ADB file access (no permissions) 4. ADB downgrade install to pull old files (failed due to Android 14) 5. Accessing "files:///data/data/org.mozilla.firefox/..." (cannot download files and looking at the timestamps, the SQLite files have probably been overwritten) 6. Firefox debugging (Nothing useful) 7. Searching for a way to get Firefox Sync historical data (doesn't seem available) 8. Mailing customer support (No response)

Things I didn't do prior to this incident (answering the common responses found online): 1. Bookmark my tabs 2. Firefox Collections

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

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...

Hi,

I can't seem to retrieve all of my Firefox bookmarks or passwords on this new mac laptop. My other (mac) one fried. I thought everything was saved on Firefox.  Tried to sync from phone (android) too. Therefore, I'm having a hard time logging into certain accounts, which I depend on Firefox for my saved passwords. (evidently that is a thing of the past and I will now write all passwords down in a safe place. Also does anyone know why when I scroll on my mouse I have to scroll up, in order to scroll down, more importantly how can I change it back. This is a new glitch. and I'd rather not get used to it! Please help if you can.

Thank you, techno dummy Noel lol
