For years I had my Firefox sync working fine between Win10 PC, Android and several Win10 laptops. However yesterday I installed Windows 11 on the same PC I have Windows 10 (bought new disk) just to have a fresh install. Started with installing firefox - and here when problems begin. It couldn't let me log in into Sync, I was being immediately logged out ("Account disconnected"). Somehow I managed to log in, but then all my previous data was erased (passwords, bookmarks). I thought ok, maybe later it's gonna sync. Started installing extensions, saved one password. When trying to sync tabs with Android phone it didn't work, it couldn't see any tabs (but it could share tabs between devices!). On Android I still have old passwords and bookmarks saved, same as on old Win10 (on which I got logged out). Alright - it didn't sync after restart so I removed Firefox profile on machine, started again with logging in - and it synced only ONE password that I saved previously on same Win11 machine, with extensions I freshly installed back then. So it saved to sync improper data, forgetting about old? Logged out from all of my machines in Firefox Account. Now I'm back to my original machine on Windows 10. And what? I can't log in! Same error as on Win11 after install - "Account disconnected". Checked about:sync-log and found error logs - pasted into "Troubleshooting information" of this post.

Thanks

When using university computers, I log in to Firefox Sync so that I have access to my bookmarks and tabs from home. When I do, Firefox will ask to save passwords on my home computer and phone again, even though I had it disabled in the past. Is there a solution for this, other than disabling it manually every time?

Thank you for your time. I'm posting this from my personal computer, so I'm unsure what version of Firefox the university PCs run, but if necessary I can find that information.

Recently I reinstalled my Windows 11 system, and even though I synced my Firefox account before reinstalling the system, there are no passwords, settings and extensions, which should be synced.

I searched for the same problem, but all I could find was searching for profile files in C:\Windows.old

The issue is I do not have Windows.old folder or anything like that.

Is there any way to recover at least my passwords?

Thanks in advance for help.

nevermind. fixed itself. maybe it just took it a lot longer than expected

I have two firefox accounts. Got a new computer and trying to sync to the new one. I have tried to sync both of them. But only 34 of 300 passwords transferred and only 20ish bookmarks of 100s transferred.

I have tried looking into both accounts on both computers at the same time, run sync, but nothing more will transfer

Please help an old dummie? I have an existing FF install on a laptop. I would like to clone it (with bookmarks, settings tiles etc) onto a new PC. An article I read said open FF on the PC you want to sync. This is confusing! "Synchronising" is ambiguous, meaning 2-way. (but which way) "copy from" & "copy to" would be clear. I am worried I will synch(copy) from the new to the old....... effectively deleting/wiping out all my preferences in my original install. OR (preferably) Is there a way to just copy the whole installation from my original PC onto a USB stick & installing FF to the new PC from it? Many Thanks

Hello

Out of nowhere I started having problems watching Videos on Twitch. So, after some Flatpak repairs and reinstalls, I decided to sync my data with Firefox Sync and remove it completely. For my surprise after reinstalling and logging in on Firefox Sync my only extensions and, what looks like part of my history were restored. Lost my session, custom tabs names etc.

Hi Guys, I'm having trouble logging into Firefox on any of my devices even though i can pass all the password & security steps. When logged in, it asks me if want to connect any other devices then immediately logs me out.

On my main laptop i have all my bookmarks & passwords working but am not logged in, but i want to replicate this on another laptop.

Any ideas?

An error occurred during a connection to passport.moi.gov.af. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I mistakenly removed an important extension (LinkLocker, which I wrote, actually) from my synced work computer, not realizing it would be removed from my home laptop as well.

Unfortunately, I saved a significant amount of data in that extension's storage and, after reinstalling it, can't seem to recover it.

Is this data lost forever or is there some place I can look to find it?

Recently my PC has died from the hardware crash. So I've bought another PC and installed Firefox. While other browsers seem to nicely sync bookmarks and history from the previous PC, Firefox didn't do that although I have been logged into my Firefox account on both PCs and I can clearly see the other PC in devices using this account. What is the reason for that?
