Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

My work is trying to fire me because they say Firefox was mirroring my activity at home and vice versa. I.E If I opened a tab at home it when then open a tab and attempt to connect to same website on my work computer in the office.

I’m fairly certain it doesn’t cause that would be wildly unnecessary for what sync tabs is trying to accomplish but I used wireshark to watch for outgoing connections on my home desktop and opened a tab on my phone and my personal laptop and wireshark never detected outgoing connections to the tabs on other devices

I use Sync on multiple computers for passwords. I have forgotten the Primary password on one of them. If I do a password reset on the one computer, does it affect the passwords stored on the Sync server, or maybe just the key4.db and logins.json folders on the computer being reset? I will not do a reset if the Sync'ed passwords could be affected, I'll just look them up on my phone. Thanks for your help!

When you check the image, you can see two "HOME" entries. This is an issue I discovered after uninstalling and reinstalling the Firefox browser and using Sync.

HOME is my PC, and this image was screenshot on my laptop.

Additionally, the Sync for these HOME entries is not functioning properly. I tested this by opening several sites, and while Sync works well from my smartphone to my PC, it doesn't sync properly from my PC to my laptop.

Does anyone know how to solve this problem? I tried rebooting my PC, but it didn't work out.

I recently deleted accounts and passwords that were stored in Firefox under my web browser account. Is there anyway I can get that data restored? I have access to the same email/account in Firefox, but need to restore the deleted website account/credential data.

I use Mozilla on two things, my laptop and my android cell phone. The syncing on my cell phone appears to work perfectly well. However, when I am on my laptop, I am unable to view my "Tabs from Other Devices" - It will show me tabs from days ago. I've tried manually syncing on both devices but nothing happens.

The only thing that seems to work is if I log out of my Mozilla on my cell phone and log back in but then it will stop syncing again.

If something else isn't syncing, I honestly don't notice because I don't use anything else much.

I updated my password but now when I go to sign in (since an updated password signs out on all accounts) it won't stay signed in ever on my laptop. I input the password, then the email confirmation, then the authentication, and it says I'm signed in but when I go to my account is disconnected again. I've tried many times. I've also cleared the cookies and cache. Any advice?

Dear Mozilla team, as a old fan from early days of Mozilla Firefox, Im quite dissapointed with the same issue I am facing with Firefox browser. Even I created my profile, which one you can check from which year has been created, even after I synchronised all my bookmars, passwords etc etc, still no data is restored. I formated my laptop last week and thought that this time, with syncronising I will save a lot of time buut veery dissapointed again. STILL I am not having back my 100+ login details saved on Firefox. Also tabs. Now, on my browser promts taht my account is all syncronised but still blanco browser, with not a single saved data!

I will appreciate your help to get back my data, as soon as possible.

Regards, Enis Jusufi

I'm not currently able to sign into my UK account using this link: https://www.mozilla.org/en-GB/account/ When I type in my email address and click continue I just get a circular loading symbol going round and round forever. I'm able to sign in using the US sign in link for some reason. I'm not able to sign into Firefox overall though, so none of my bookmarks etc. are synced. I have tried on two different laptops a week apart with the same results.

Yesterday, I noticed after I closed and re-opened Firefox, my browsing session was completely gone - all my tabs and windows, my entire browsing history, website sign-in status, all completely gone. I've been troubleshooting since then.

I've noticed that the 'sessionstore-backups' folder in my profile folder is missing. When I open Firefox, this folder is created and Firefox writes some data to it, but Firefox seems to delete the folder as soon as I quit Firefox. Firefox should not be doing this. My Firefox is configured to open previous windows and tabs, and is NOT configured to wipe any browsing data of any kind when it closes.

As a sanity check, I spun up a Windows Sandbox (briefly, it's a clean, isolated Windows environment) and installed Firefox there. I also enabled the option 'Open previous windows and tabs'. Firefox behaves normally - it re-opens the tabs/windows I had open when I quit Firefox. Great, that's what I expect. The trouble starts as soon as I sign in to sync. After signing in to sync, and letting the initial sync process complete, I open a couple of windows and tabs, then quit Firefox. Firefox begins nuking my browsing session again - the 'sessionstore-backups' folder is erased, and next time I start Firefox, all my windows and tabs are missing, and my browsing history is missing.

So, at this point, I'm assuming something in my synced data has become corrupt. I haven't installed any new extensions lately. I haven't changed any of Firefox's settings that would cause this to happen. The only thing I have done differently lately was enable Firefox Sync in LibreWolf and sign in to sync there. It seems like this session-nuking trouble started after I signed in to sync in LibreWolf. I assumed, since LibreWolf is a fork of Firefox, and because there were no warnings or indications the feature was incomplete/unstable/experimental/etc., that it would just work, that it wouldn't cause any issues. But it seems like it has caused issues. I checked LibreWolf's issues tracker for anything related to 'sync', but I didn't see anything noteworthy.

I've been using Firefox and Sync for numerous years without issue. This session-nuking thing started yesterday.

I use Firefox in a few places, and based on what I saw happen in my Windows Sandbox, this session-nuking issue is going to happen in every Firefox I'm signed in to as soon as it has a chance to sync. Obviously, I do not want this to happen.

What can I do to determine what the issue is? What can I do to check if something in my synced data has become corrupted? What can I do to reverse it? I'm not opposed to completely wiping/resetting my synced data, but I'd rather not if I don't have to. The only thing I would lose sleep over is my bookmarks, but I know I can export them. Are there any debug logs I can enable/look at? Anything I should look for in Event Viewer?

Thanks.

hi

XUL Runner platform version 129.01 is not compatible with 129.0 miniversion 129.0 maxversion 129.0 When this happened at first I did not have the use of Firefox. I then went to Firefox and down downloaded Firefox and started over. Then I went to go to my bookmarks and could not find them, bummer. Now I still get this XUL Runner message ??????? email guybrochu@yahoo.com

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.

I got a new Macbook Pro recently and set it up by basically copying my iMac onto it. All works great. Except that the MBP doesn't show up with it's synced open taps on my iMac or my iphone. The iMac doens't show up on the MBP either.

Have I maybe copied some setting that makes the two machines (iMAc and MBP) thinkt they're one and the same? How can I "separate" the devices so that they show up in each other's Synced Tabs lists, respectively?

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.
