Firefox Community Forum

After a few days of having no internet connection, my account was disconnected from my PC and saved passwords disappeared. After signing in to my account again and syncing, lost passwords were not recovered. I need help to recover them.

Sync is corrupting my bookmarks.

This is affecting Firefox on multiple Windows computers, and multiple Apple devices (phone and tablets).

Only partial data is available. The bookmark “tree” structure is complete, but the bookmarks are only partially populated (only about 15%, and it appears these are newer items).

I did not change/edit any bookmarks or Firefox settings. This did not occur after a Firefox or OS update (it has simultaneously affected Windows 11, Windows 10, iOS 26.2.1, and iPadOS 26.2.1 devices, Firefox 147.0.2 on the PCs, iOS 147.2.1).

One one computer I momentarily saw all the bookmarks (machine version) disappear as Firefox synced the corrupted version to that computer.

I know I can restore the bookmarks (at least temporarily, until Sync may re-corrupt them). What is causing sync to change MY information?

I am signed in on all my devices. Yet nothing has synced since October 2025. So none of the books marks from my laptop display on my desktop in bookmark folder. The folders don't even match what is on my laptop. How do I fix and how do I prevent in the future?

I'm on week 3 of attempting to import my firefox data I'm stuck on the already synced to profile create another. I am unaware that I have any profile at all and I don't want any profiles. Is there any means at all of retrieving my passwords and bookmarks from my old laptop without having to deal with this crap?

I have 4 macbooks and iphone w. about 10000-19000 bookmarks. Last n. I noticed what I bookmarked on 1 machine wouldn't show on another. A pop up said "your profile has reached a limit. A device can have ony one identity..make another (sic)...." I did that, and found the bookmarks from "classic" profile, WHICH I'VE HAD ABOUT 20 YEARS, weren't imported. I uninstalled, reinstalled Firefox, managed to get the bookmarks back via a desktop folder I'd made, thank god! It didn't restore the 50 passwords, and still won't accept the previous password..which is another can of worms-it actually won't let me change my p/w w.o "you may lose your personal bookkmarks passwords etc!:" Even the 32 digit code (which I had saved) is not working...and it doesn't let you get another one unless you have a p/w!!!! Is this sounding a vicious circle....I am going to not use sync or another profile, b'c I'd rather keep my personal data (bookmarks) and rightnow, I was able to 'restore' to the original profile!!

Hello,

I'm unable to find the sync bookmarks,

I'm trying for a long time, in my iPhone and MacBook, both Apps are the latest, using the same email and the Bookmarks do not show in any of the devises.

Can you please help me?

They [rimary password quit woking so changed it in mozzzila account which I'm logged into the browser, but it will not allow me to change the primary password in the browser or access a lot of stuff, . I updated the Password in the Mozzilla account, and since doing that the browser fails to sync.

I cannot figure out how to fix this in a lenovo laptop running stupid windows 11

When I choose add new device the website displays 2 choices: mobile with installed Firefox app or need to download the app.

I chosed mobile with installed app then the website return to this main page without show the QR to scan from app.

Now, I logged in using email on my Android mobile and failed to sync my web browser profile..

I've installed FF on new computers a few times in the past year and I've noticed that it never syncs the Search settings (things like default search engine, adding StartPage, etc.). Is that by design? Is there a way to make them sync?

I had to have my laptop serviced. When it came back, I downloaded Firefox and logged into my account. Usually, all bookmarks and passwords would load back up, since they were bound to my account. Unfortunately, this time after had synchronization finished, none of my data was present. It's as if my whole account was wiped. The only thing I did was change my password. How can I restore everything?

Dear Sir or Madam,

I'm recovering an older Firefox Sync Account. I can login on https://accounts.firefox.com. My password is valid. I cannot login within Firefox (activating Sync). It simply does not continue - After entering the E-Mail-Address and clicking the Button "Sign up or sign in". The browser network debug show no (obvious) communication error.

Please advise.

Kind Regards, Stefan

Recently, Firefox has been slow and crashes regularly. I try to sync tabs but after it crashes and I reopen it goes back to a much older save and lose tabs I've recently opened or sometime after a crash and reopen it tries to open a window with no tabs and I lose all my tabs

Hello, I just completed a wipe of my whole device, beforehand I obviously signed up and synced up my Firefox account to keep my boomarks and data. After reinstalling Firefox I managed to sign in, sync up and get my bookmarks back - great. However after reopening of the app they were gone again and when checking back-ups the only available one was from after the "automatic wipe". I quickly checked my mobile Firefox app as well - it still showed a bigger of number of bookmarks so I had hoped they stayed at least there but after entering the folder they appeared empty and then gone completely after re-entering. Please if possible assist, it seems like Firefox decided to overwrite this data so maybe it's still somehow recoverable as these bookmarks have been collected over the years. Thank you in advance.

Hello, in the last couple of days I spent a lot of time deleting old accounts stored in "passwords" in my Firefox account and making sure no vulnerable passwords were still around. I did it from my Mozilla account, on a laptop.

When I was done with it, I signed out from my account on my Android Firefox app, and deleted all the cache and the data, to remove all the old password. Unfortunately, when I looged back in my Firefox account, the old passwords were still there and synced on my laptop as well.

So, is there any way I can undo that Sync? The problem is that now not only all my cleaning pointless, but I changed the password for many accounts and the Sync override it with the old ones.

I have about a dozen computers synced to Firefox. The Bookmarks go nuts when an older seldom used machine powers up. I spend days cleaning out my bookmarks only to have old ones come roaring back. I have began manually backing my bookmarks up to a hard drive. Firefox has failed me. I wish to delete all, or some of the backed up bookmark files.

How do I do that!!! I've spent hours over weeks online trying to stop this madness. Can I wipe out all the files by deleting any of the three "places.sqlite files? Is there a way to selectively kill the very large files that keep coming back and keep the other recent backups?

Does someone sell a pay to play bookmark manager similar to Foxmarks / xmarks?

Thanks for your help Lee

I bought a new PC and when I try to sync to the browser I don't receive the confirmation code by email (yahoo). I saved the address in my contacts, nothing. The problem has persisted for more than a month. What can be done? Thanks
