I-Firefox Community Forum

In the past I have had several computers synced together to keep bookmarks the same on each computer. Now I sometimes get the bookmarks but the links on the bookmarks are all changed to other sites. Everything is scrambled. How do I get a couple of my computers all syncing to other computers.

My bookmarks bar, etc have will not synced with my Firefox even though I ran "sync" several times. I haven't used this laptop in quite awhile, so I had to log in and sync. Also in my themes, a certain creator "MaDonna" has error messages on all of them" Cabin in the Mountains (and all others by her) by MaDonna could not be verified for use in Firefox and has been disabled." In my extensions page, I get the same error message. I am beyond frustrated, I'm also very computer literate, but this mess has me baffled and frustrated :(

I have a Windows Surface Pro 8 and when I set it up, I had no issues with the Syncing or Add ons/Themes/Extensions, everything synced just fine. I have Theme categories set up, and that's not even on the Themes page. I have logged into all of my Firefox/Mozilla accounts. Can anyone help?

Здравствуйте, проблема с восстановлением моих закладок. Дело в том что я продал свой пк и купил новый. И когда установил браузер. Вошел!! В свой аккаунт где были сохранены вск мои пароли и заметки просто исчезли. Я не знаю что делать. Доступа к старому пк у меня нет. Я не понимаю почему браузер не хочет восстанавливать мои закладки и все сохраненные сайты.

Dear Support,

Since ages ago I've always logged into Firefox and turned on sync so whichever device I was on (or if I have formatted my PC) I would still have acces to my browser history, tabs etc. Today I've formatted my PC to switch from win 10 to win 11 and logged into firefox as usual, but after trying to Sync nothing happens. My tabs, my history, everything is empty for some reason and I cannot find my original device (the one from a few hours ago connected in win 10) in my connected devices list either.

Please help me, my whole life is in that sync :(

Best Regards, Peter

i have opened my account on firefox and it has a very old version of my bookmarks, i have logged in to the same account on both computers and it isn't showing up on the new one

Hello Mozilla Support Team,

I am experiencing a critical Firefox Sync issue and would like to request your assistance.

I recently installed Firefox on a new Windows system and signed in using the same Firefox Account that I have used for a long time. Although my account shows recent activity (last connection around mid-February), none of my synced data has been restored on the new installation.

The missing data includes:

Saved passwords (logins)

Bookmarks

Firefox preferences/settings

I have carefully checked the Sync logs (about), and they indicate that collections for passwords, bookmarks, history, and preferences do exist on the Sync server. However, the new profile does not download or apply these records, and Sync appears to treat the new local profile as authoritative.

I suspect that repeated sign-ins and sync attempts from a fresh profile may have caused my previous data to be overwritten or made inaccessible, even though the server still reports existing collections.

Given the importance of this data, I would like to ask:

Is it possible to restore my Firefox Sync data (passwords, bookmarks, and preferences) from a snapshot or server-side state from approximately 20 days ago?

Is there any way to force a full restore from the server instead of uploading the empty local profile?

Are server-side backups or recovery options available in cases like this?

I fully understand that Firefox Sync uses end-to-end encryption, but since the data was previously accessible under the same account, I am hoping there may still be a recovery option.

Please let me know if you need any additional information, logs, or identifiers from my account or device to investigate further.

Thank you very much for your time and support.

Kind regards, [edited email from public community support forum]

Hi.

I had to install a new OS disk. So, I created an account, and made a synchronization. Then, I made a security backup. When I installed the SO and Firefox, I logged in to sync. As soon as I logged, it automatically started to sync the random tiles it had after install. So, I had to use the places.sqlite and favicon.sqlite files. It got me half the tiles, and even those were misplaced. So, I had to go for the security html, and I finally got everything I wanted. But, now it says the account is not associated. If I login to associate it, when I shut down the PC, it returns to those half tiles, and out of order.

How can I get this right?
