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.

Hello,

I have a firefox Account "accountA" which has the primary eMail-Address "mailA". I had an other Account "accountB" with primary eMail-Address "mailB" and secondary eMail-Address "mailC". Sadly I lost access to "accountB" and it's primary Mail-Address "mailB" (which is ok) but want to change the Mail from "accountA" to "mailC".

However, this is not possible since "mailC" is locked to "accountB" which I can no longer access (since I need the primary Mail Address. This meens I can never again use "mailC" for my Firefox account, which is now my primary Mail-Address. Is there should be a way to disconnect a Mail-Address from an account, if one has ownership of this Mail-Address?

I reset Windows yesterday to attempt to fix a problem with my computer. After redownloading Firefox and signing into a few basic things (including my Mozilla account), I realised all my logins were gone. I have followed the steps in [[this tutorial|https://support.mozilla.org/en-US/questions/1310179]] but it didn't work - I think saving logins in this instance of Firefox overwrote the other logins file, as when I opened it, it only had the login info from what I logged into after I reset.

Looking at my connected services, it seems the instance of Firefox from before I reset is still open. I mention this just because it's possible that this would contribute to a solution.

Any help is greatly appreciated as I have a number of securely generated passwords and cannot access a good deal of my accounts.

I know the answer to this is probably going to be along the lines of this is not possible, but I thought I'd ask anyway since none of the information is entirely clear. Or answers my exact question.

I have one desktop install of firefox and I have two android ones. I have all three synced to one firefox account, so it's easy to grab links I saved while wiki diving on something. While this works perfectly for the desktop side of things, the mobile side is where the issue arises.

Currently all my bookmarks from both mobile firefox accounts are merged into one long set, regardless of device. While the desktop ones have their own folder. Is there a way to keep the bookmarks from each device in their own separate folder? Like say instead of having one big mobile bookmarks folder, having one named DeviceX, and the other DeviceY?

It's still semi functional on desktop where I have more screen real estate and have to deliberately go to the mobile bookmarks folder, but on the phones it can be confusing when a set of bookmarks from device 1 mixes randomly into those of device 2. As it can become a lot harder to keep track of things.

Now I know one can turn off syncing of bookmarks. This is not what I'm looking for as I do still want to be able to share them between all three devices. Just have them more organised.

I also know one can make different accounts for say work or personal, but again I want them all to sync, just not mix them into one list.

So in short is there a way to be able to have two android devices into a threeway sync and keep the bookmarks separate? Or is my only option the round abound way of making subfolders and hope I remember to save in those?

Thanks either way.

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

Recently I had un/reinstalled my firefox via snap and apt from linux. I'm signed into my account yet locally I'm not getting data to sync across devices. Any idea?

My workplace bans Firefox. It is not possible to install it in any way on any computer. I still use Firefox on all of my personal devices, and heavily utilize the Firefox Sync to keep my Bookmarks in sync across devices. I need to be able to access my Firefox Bookmarks somehow from my work computer, so I can at least retrieve recently bookmarked items.

I am able to log in to my Firefox Account https://www.mozilla.org/en-US/account/ and see my Firefox account details, but this does not include any of my Sync data.

How can I access the contents of my Sync data? I do not even need it to be integrated into another browser, I just need to be able to access it somehow from a computer that is not able to have Firefox installed.

There is a similar question here https://support.mozilla.org/en-US/questions/1255784 which provides a non-functional non-answer which is not appropriate and does not work.

I am sorry that my letter has caused you trouble but I have to ask you for help to solve the problem I was facing. I forget to save my account Password when I uninstalled the Firefox browser and I didn’t log in to my account at the time.But I’m in hurry and need it too.Can you help me get it back?Thank yo very much! And the website is pog.org

Sadly, I am now forced to leave firefox. My passwords are getting "forgotten" more and more each day. Did i get hacked? Few passwords like proton mail I don't actually have anywhere else. Auto-Backup of firefox seems to be of the same day as the original??? So it loses the data then saves it twice? who designed this? I'm angry, not at firefox/mozilla. angry at myself for putting my trust in the first place. Chromium doesn't sync so it leaves me with chrome FFS. Does someone has a magic wand to recover the lost data? login.json is same day as original so not an option.

Hi. I want to sync with my work pc (it used to work just fine but when I synced to a newer third pc- successfully- it just stopped). When i try to sign in on the work pc it asks me for the primary password which it then FAILS to recognise to allow me to proceed! What's going on? I can't even log onto sites with saved passwords anymore. Any help appreciated.

I have two notebooks with Firefox (NB1 and NB2). NB2 rebooted and Firefox restarted losing all open tabs; now I would like to bring the tabs from NB1 to NB2; both have synchronisation enabled, but when I go to ‘Settings, synchronisation’ on NB2 it says ‘Synchronising in progress’ and nothing happens. I've also tried going to NB1 and sending a tab to NB2; I select NB2 and nothing happens.

My NEW M2, Windows 10 drive failed catastrophically. Am having to rebuild my system pretty much from scratch. I have the old failed, Windows 7 SATA drive. It will not boot, but the data is mostly intact and accessable. I want to sync my new Firefox install from the old, but I need help.

I met the same problem as https://support.mozilla.org/en-US/que.../1191123

I have read this https://support.mozilla.org/en-US/kb/forum-response-firefox-sync-verifica...

I have tried waiting for more than 24h, not working, and submitted a request at Bugzilla (maybe it's because I didn't write the request in the right way so I haven't got response yet).

I have some so many bookmarks in my firefox account and passwords in my lockwise account. Please help me out, my account email is xxxxxxxxxx@xx.xxx

(email address phone number removed by moderator; please do not post personal information on a public website)

I have both Win7 and Win10 on separate drives. I have been migrating from 7 to 10. From all appearances Firefox on both OS's are sync'd. I have asked for my passwords to be sync'd, yet they have not migrated to Win 10. Bookmarks have so I know something is working. Any advice? Thanks Chris

After up grading to a Mac Studio running Os 14.5, I downloaded the latest Firefox 126.0. I have three other computers with Firefox. The oldest a Mac Pro running 10.13.6 Hi Sierra that works flawlessly. I tried sync and bookmarks came over to the Mac Studio but not any passwords. I tried importing via a .csv file and got the message: Import complete New passwords added: 0 Existing entries updated: 0 Duplicate entries found: 0 Errors 190 (not imported)

Firefox will NOT even save manually entered passwords. I suspect some problem with Sonoma's paranoid security but I cannot find a solution. Any suggestions?

Hiya good citizens of the internet 👋

Please help me recover my bookmarks 🥺

I've gone through every single support article on this topic and tried everything suggested and still no luck. This is my hail mary.

How I got here I needed to do a full wipe and reinstal of my macOS; this was conducted with the help of the Genuis bar. Upon reinstalling Firefox, I signed into my account and my bookmarks are all gone, records of them empty.

I should also note that nothing else ported over. No passwords, no browser extensions. Nada. The passowrds and extensions aren't a big deal. I use a 3rd-party password manager and can easily re-download the handful of extensions/widgets. But I heavily relied on bookmarks for both frequently visited sites and ones rarely-used which I knew were important for future reference. And I cannot remember 80% of them...

What else I've tried other than what's suggested in help article:

• Because I did not check to confirm which Firefox profile I've been signed into for ages and ages before doing the reset, I thought maybe I had just signed into the wrong one. I proceeded to try every other email address I have, including two from my old workplace. None of the other 5 emails had profiles created. I know this because it prompted the sign up userflow; create a password, etc.
• But I also know for a fact that the bookmarks were saved as part of a profile because I used the profile sync feature to auto-port all my bookmarks when I first got this Macbook a year and a bit ago.
• The folders where bookmark backup info is stored locally are empty... Clearly, it wasn't stored in my icloud documents (that's on me for not double-checking)
• I checked my other device (mobile phone) to see if I had firefox downloaded and was signed into the same account as the original, with the bookmarks still visible. Of course I didn't. I only use Safari on my phone 😭

""Grasping at straws: the only other things I can think of""

• Is there some way of linking my MAC address with my IP address and using those to triangulate the correct profile?
• Because my computer got wiped and nothing is saved locally, my only hope is that my bookmarks are floating around the ether. If so, I just need to figure out how to find them.

Any and all help/suggestions are massively appreciated!!

Thanks in advance,

Lauren
