"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

I had to re-installed from 0 my windows. I was sure my Firefox account had all my passwords and logins because I had problems in the past regarding this. Installed Firefox into my new fresh windows. Hit the Sync bottom. Lastly, remove the old Firefox account login from old windows (for safety).

Now I checked password, 0 passwords saved.....

I am trying to re-sync but nothing happens...

Hello,

Earlier today I reformatted my device but when I logged in to firefox I can only see my history is getting synced my bookmarks are empty, I've checked and bookmarks are check off and they should be synced. How do I get them to sync? It has worked fine in the past. Thanks.

The subject says it all. The "tabs from other devices" are a) Shown as a long flat list of links, not in their individual tabs, which is disappointing b) right click does nothing - doesn't open them as advertised

I signed into my firefox account on my wife's computer and now ALL of her bookmarks, passwords are mixed in with my data. I've signed out of both accounts on that computer. I've signed out and relogged in on my computer. This is not a temporary issue. All of her data is somehow in my account. This seems like a MAJOR security flaw of the software. Were both using Windows 11 computers.

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.

I installed a new Windows 10, then I installed the latest version of Mozilla Firefox v133 and there's no sync option in this version 🤔 What is the problem?

I want to recover my bookmarks and passwords

Any solution?

As you can see in the picture

使用系统：win11。我在之前的Firefox上已经登录了账号并开启了自动同步，前天我重新安装了系统并下载登录了账号。登录了账号之后并没有重新同步我的书签，我手动同步多次没有结果，并等待了一段时间自动同步，以及观察是否会同步书签到本地，结果仍没有。于是我尝试用我手机的Firefox登录电脑的Firefox，结果才同步了我手机的书签信息，但我手机的书签信息已经过时。而且电脑的Firefox显示可以和手机的Firefox互相同步信息及标签页等，但我观察后发现并没有完全同步，我电脑/手机的信息及标签页都是一天两天之前的，手动同步后仍然没有看到有更新。我希望同步回服务器的书签信息！

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

Yesterday I only change the photo in my Firefox profile. Today I can't log-in to synchronize my account. When I click on "Anmelden" (German for "log-in") at the top right corner, a new tab opens, I can enter my e-mail adress, klick onto the button "Anmelden oder registrieren" (German for "log-in or register") it fades out and nothing else happens. I can access my account here as I logged in to send this message. What is the issue? How can I start synchronizing my account again? My Firefox version is 146.0 Thanks in advance, Chris

I upgraded to Windows 11 yesterday. I have always been logged in to Firefox with my email, so I thought the bookmarks will come back once I log in on the new windows, but that didn't happen. Some of these bookmarks are work related, so they're fairly important.

Although I'm using the same email, my profile picture is gone too—replaced with a default one. (Not AI generated sentence. I just like using Em dashes)

What could have happened and what can I do to get my bookmarks back? I appreciate any suggestion you can give me.

Thank you in advance.

I can no longer see a list of tabs from other devices. My computer was wiped recently and I was using the tab sync function to see the tabs I had open before the wipe. Now they have vanished. How do I get them back?

Hi,

I changed my password in my Mozilla account and now I can no longer sync my firefox for android.

I scan the QR code and on my android screen proceeded normal and asking me to confirm but in my desktop I get an error.

"General application error Something went wrong. Try again later."

I also tried in safe mode with no luck.

What to do now?

I've synced all my data (including add-ons, passwords, bookmarks, etc) to my firefox binded account on fedora linux then change my linux distro and re-setup firefox on Manjaro KDE, login and etc

found out that everything synced but my previous add-ons and open tabs are gone for good I've so many opened tabs are my custom add-ons settings on so many add-ons for personal preferences are gone

I've faced this many times but I thought somehow these days firefox might have fixed these issues but i'm so sad that all my important data are gone :(

I'm using firefox only just for sync+privacy for hassle free setup again and again over many devices otherwise i prefer tor for much anonymity and privacy

PLEASE, YOU GUYS CONSIDER WORKING ON SYNCHRONIZATION FEATURES SPECIFICALLY <ADD-ONS> AND <OPEN TABS>

thanks for reading and pl igonre my english errors
