Hello,

I have been using the same Firefox Account with Firefox Sync for several years.

I always reinstall Windows using a full disk format, and I have done this many times over the years. I have never signed out of my Firefox Account before reinstalling Windows, and Firefox Sync has always restored all my passwords, bookmarks, history and other synced data without any issues.

This time, after performing the same clean Windows installation and installing Firefox again, I signed into the same Firefox Account using the correct email address and two-factor authentication (Authenticator app).

I have verified that:

I am signed into the correct Firefox Account. Two-factor authentication works correctly. Firefox Sync is enabled for Passwords, Bookmarks, History, Tabs, Add-ons and Settings. Only the two new passwords I created after reinstalling Windows are present. All previously synced passwords, bookmarks, history, tabs and other data are missing. My Mozilla Account now shows only the new device. The previous computer is no longer listed.

I also checked the Firefox Sync log. It contains entries such as:

No metadata record Fresh start Wiping server data

Since I have successfully restored my Firefox data after many previous clean Windows installations using this same Firefox Account, this behavior is unexpected.

Could you please check whether my Firefox Sync storage still existed before this device connected, or whether it had already been reset or become empty?

Is there any possibility that my previous Sync data can still be recovered from the server?

Thank you for your time and assistance.

this is my back-up laptop, which until recently synced perfectly with the main one. now all bookmarks are missing, and I cannot understand what is happening the background.

With Firefox Android on my tablet, bookmarks are not syncing that i see when logged into my Firefox account on other devices. I tried logging out and in to my Firefox accont and also unchecking and checking the "sync bookmarks" box. Firefox Android says "bookmarks are now synced". But they aren't!

So I just switched OS on my desktop, and had to log into Firefox all over again for the first time in a bit, and it turns out that for some reason my saved passwords arent synchronising with my whats saved on my phone? In the past my experience have been that if I ask firefox to save my password on one device it remembers it on all my devices. Is this not the case? Is there something I need to do to manually synchronise?

Firefox desktop saved logins not appearing on android. Sync enabled on both devices yesterday. Previously worked fine, kinda frustrating having to manually re enter everything.

Firefox is disconnecting my account every time i restart the browser. I've made sure it's not set to clear data when restarting. I found a support forum post for mac where they weren't installing it and were running it from the dmg, but i'm using the firefox that was installed during cachy installation, which firefox gives /usr/bin/firefox, when runnign it from terminal (or anywhere) the command in btop is /usr/lib/firefox/firefox. its really frustrating because i lose my session data, have to log back in again, have to redownload all my extensions, ahve to reconfigure all my extensions every time the browser restarts

I'm on CachyOS on COSMIC de with a btrfs file system. I've tried uninstalling and reinstalling firefox. I've tried making a new profile. I really don't want to use a different browser, but this isn't functional.

I am using the same account (my school email), and everything else sync successfully.

Tab groups saved on my Windows PC didn't show up on my Macbook; tab groups saved on my Macbook didn't show up on my Win PC. Is this a feature or bug?

For years using firefox, I have had all of the bookmarks and login information retained by Firefox on my old HP laptop, but after buying a new Windows 11 Laptop and performing the Firefox syncing, none of the bookmarks/favorites and none of the password (and other items that used to self-populate) are there on my now machine. This has caused an emergency situation since my old laptop is now fatally broken. I'm wondering how to start diagnosing what the problem is, whether the "syncing" actually occurred within my account, while the syncing process indicated no problem. The new machine has it's own Bookmarks toolbar showing, but only contains a few new bookmarks that I have manually added.

I have been using a new windows 11 laptop, but which hasn't been able to import my favorites/bookmarks as well as password data from my previous (also running firefox) Windows 10 laptop. I performed syncing, but which didn't seem to help.

I have tried to look for my profile and it isn't there, I can do it through my mobile but when it syncs it doesn't add the Bookmarks I have saved there either to my PC

I'm the I.T. Director for a school and we use the Securly filtering system. I can't get Firefox sync to work behind this filter. What is the URL that Firefox is trying to connect to for sync so I can add it to the whitelist? Or, IP address. Also, does Sync use my system DNS or does it have some sort of internal DNS that it queries for sync? Because I recently found out the hard way that I have to use the Securly's DNS IP's or nothing works.....

After reinstalling my computer system, I logged into my Firefox account again, but the data synchronization failed. All my previous data is gone, including bookmarks, passwords, and widgets. What happened? I can't find them in the mobile app either.

I tried to sync my desktop and mobile today. Nothing loaded to my mobile a fact I am now gratefull for because my desktop did sync with the cloud ERASING an entire year of deleating broken bookmarks. What I want to know is how to deleate the cloud so this never happens again!

i have changed windows and i put the same old account on firefox but still not recover my old browser data or passwords , etc i loss everything , please help to recover all my data

I opened up Firefox for the first time in a while on this newer laptop, and all of my bookmarks are missing. I recently opened Firefox on my work desktop, and they were all there.

Any help would be appreciated!
