Hi, I recently upgraded my computer and as part of it had to reinstall Firefox for desktop. When I did, I noticed that none of my passwords, bookmarks, and such had transferred over. I tried hitting the 'Sync Now' button in the settings, but nothing happened. I then checked my phone as I had Firefox installed on it, and all my data was still there, and tried hitting the sync button, but nothing happened, the button just highlighted every time I hit it.

Going through the 'connect devices' route in the desktop settings, it popped up a qr code for me to scan, but the steps it outlined didn't make sense as there was no 'sync and save data' button to hit, as apparently with a recent update they removed that and folded it into the account menu - the same 'Sync' button I had tried fruitlessly before. I also noticed that no matter how many times I hit the button, it just said 'Updated 1 hour ago', indicating it was not actually syncing. Even when I changed the device name on my phone to 'Firefox Mobile' and then hit sync, my passwords and bookmarks didn't copy over, only the new name it seemed.

I then tried uninstalling Firefox from my phone and reinstalling it, and this time the option to scan came up during the install, but now my phone doesn't have any of the data I had been trying to recover. Additionally, in my Mozilla Account page it shows the desktop app, the new phone install of Firefox as 'Firefox on samsung SM-S921W', and the original 'Firefox Mobile', which presumably still has all the data I have been trying to recover with no success.

Please help me get my data back, I need my bookmarks and passwords primarily and believe they may be locked onto the 'Firefox Mobile' device, if they are stored anywhere at all. Even if there's an older partition of my bookmarks and passwords from a week past or some such that could be recovered would be greatly appreciated. Additionally I would greatly appreciate if you could make the Sync feature actually functional, as this has been rather stressful and aggravating - that data has been collecting over the past ten years, minimum, and some of it is rather critical.

Thank you for your time.

Is there away i can get my browser history and data back ,i logged out of windows couldnt remember my password ,logged in with a new password and all my data is gone .....

Today firefox deleted my complete history with the latest update. My data recovery tools cannot find any old profile. I demand a solution, since you update without any warning or possibility to save the history/tabs.

firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!

Under Settings; Privacy and Security, my Passwords have disappeared, and at the same time all of my Bookmarks disappeared also.

While I was online this morning, all of a sudden my Mozilla tab went blank and the Firefox Icon on the bottom tray disappeared too.

All 3 problems happened at the same time.

This is a disaster for me.

Can the Passwords be restored? What in the world happened to my system?

Thank you.

Logged into my Firefox account and after restarting the browser my tabs and browser history are gone. Every file in "sessionstore-backups" is also deleted and now only has two newly created recovery files. Why did Firefox delete my desktop browser session after logging in? Can I somehow recover my old session or maybe at least my browser history?

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.
