Firefox keeps just not work after I restart my Mac on the latest OS.

Now I have reloaded firefox and all of my bookmarks are missing and the account is unscynced?

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

I switched from Windows to Linux. I have signed in and tried retrieving bookmarks, browsing history and passwords, AFTER already having formatted my computer and deleted Windows. I signed in to the same account, had syncing on, but i can't seem to get any of the stuff back. I didn't have any additional backup files with those. Is there anyway i could somehow restore it all? The bookmarks are most important to me out of those. I'd be extremely grateful for any help

My computer crashed and after restarting I have lost my account data including profiles, history, bookmarks, extensions, open tabs, etc.

I have tried the basic methods suggested online like looking for hidden profiles, finding a folder for old Firefox data on the desktop, restoring from apparent backups that are meant to be there, etc. The account should have been logged in all this time and had sync on, which is not working... but should there be some sort of sync history I can restore from? Or a local backup from somewhat recently?

Thank you

Quite simply I replaced the dead power supply on an old PC of mine and booted it up to start using it again as a work PC.

When I did the now decade old version on firefox told me I might want a clean reboot which I clicked Ok since the history was so old on it as to be irrelevant. Firefox closed but didn't reboot. So I launched it again and simply chose not to restore the old tabs when prompted (not even some of them as that was also an option). I updated the old version on firefox I had on it before restarting it and logging into my firefox account to sync and try to transfer my work tabs to the old PC. When I did so I realized on the old PC that reopening Firefox didn't reopen where I had left off. I thought it was just the update but did a check nonetheless. Opening a couple of random tabs before exiting firefox and launching it again. It didn't reopen the last tabs. I checked the settings: "open previous windows and tabs" was checked. Did a brief google search that confirmed my next step: uncheck that box > exit firefox > launch firefox > check the box again > relaunch firefox. I did all that and was still not getting my tabs back.

Then I went back to my current PC (where I had changed nothing) and missclicked (I think I was going to the settings) exiting firefox there (3 windows and probably ~60 tabs ... yes I have a problem). And now even on my main PC firefox didn't restore windows and tabs!

I hoped I could go to history > reopen closed windows but no dice. The option is greyed out. That is also when I noticed I had no history whatsoever.

Now I unfortunately relaunched firefox a couple of times here trying to troubleshoot BEFORE I went online and saw that I could have possibly restored the last session using some backups.

With all that in mind can I still restore my tabs/history somehow? And why isn't firefox picking up where I leave it even though the option for it is on?

All of this is on firefox v148.0 on win10 for both PCs if that's relevant.

Thx in advance for any and all help!

Firefox keeps forgetting my bookmarks, so I uninstalled and reinstalled Firefox. After reinstalling, Firefox defaulted to my wife's profile. I then tried to recover an old backed up profile using sync. I selected the right profile, but Firefox reports there are no compatible files in any of several backup file folders.

I just reinstalled my OS (Windows 11), and installed Firefox, logged in, and just couldn't believe my eyes. Everything is just gone. Passwords, history, everything. Why then Firefox Sync is using email and password if it doesn't have any cloud storage for passwords and doesn't even work like chrome? Should I install Firefox on my iPhone to regularly sync two devices (manually), to store passwords on another device, then sync back?

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

Restarted my browser to update, and it 1. crashed my computer, and 2. erased all of my bookmarks and previous information. When I tried to log back in, it said that I couldn't restore anything and that I didn't have an account with my information already attached, even though I've been using FireFox and have saved bookmarks for years. How do I get it back? I know it exists somewhere, so I don't understand why I can't find it in the app now. It doesn't make any sense why it would seemingly crash my computer, too. Please help.

Firefox has reset entirely.

All of my profiles, bookmarks and saved passwords have disappeared; only history from this session appears. When I look at "Sync" I see the tabs from one of the profiles in the "Tabs from other devices"... it looks like Firefox thinks I have signed in from a new device, but I haven't.

The "tabs from other devices" lists the tabs from one profile under the correct device name. I am hoping all of the profiles, bookmarks, passwords etc are in there still. How do I "reclaim" these profiles on my laptop?

Where is this information stored so that I can access it?

You jerks deleted passwords and bookmarks I needed for work just because I reset my password to login. Why in gods name would you think that's a good idea? Why would I ever use your sync function if you're gonna delete my data the moment you get the chance?

To whom it may concern,

After the latest update I was met with a blank profile, no saved data, even when syncing with my Mozilla Account. I followed the back-up instructions by the support team described in the forums, but it wasn't enough. Common sites I frequent like youtube and gmail were not indexed, the passwords and logins were nowhere to be found. I really don't get what's going on, or why would the Mozilla Account wouldn't recover the data, while leaving that to profiles. Is there any way to recover it further? Or even disable profiles?

Thanks in Advance,

My firefox recently crashed (f5ea38ba-f4f8-4224-8ab8-982e19cc72f7) is the crash code if that helps it happened just now, i dont have any additional profiles and no folder such as "old firefox" is there any way i can recover all the information and my old settings or passwords or anything? I tried to log into my firefox account to sync up data but there was no update on the information

Hello,

I am contacting you because I have a colleague who lost all her bookmarks when migrating her Mac computer. She was syncing with her Professional account. When she migrated and used her account to recover her bookmarks, no data came back. Her laptop was wiped and then reinstalled, so it is not possible to recover any data from it.

Would it be possible for you to find his bookmarks?

Thank you for your help.

Best regards,

My pc just did the latest update, the one with the new Logo. It wiped out all my bookmarks and passwords. I can reset the passwords, but I have hundreds of hours of research which was all bookmarked. I have changed laptops four times and each time I did, I would just sign into my Mozilla account and it was all downloaded into my new one.

Did anyone else experience this and were you successful in retrieving this data? Do you have any tips? This was important information on a health condition and I don't know if I can find all of this again.

Please, please help. I tried doing what I found in your forums but nothing helped. Could it be that the information was wiped out by your servers and it's permanently gone? I really need help. Thank you.

I have lost my passwords on my desktop. I still have them on my mobile. I am currently logged on to Mozilla on my Desktop. If I log on to Mozilla on my mobile and select "Synch" how can II ensure that the mobile passwords replenish those on the Desktop and not vice-versa?

Hello, I had 2 open firefox windows on each of my monitors. I was doing work and at the end, I closed every window on my PC. When I came to the firefox windows I closed my "secondary" window first and it said "would you like to close 3 tabs" and I clicked yes. That is pretty normal, when you have 2 windows. Then I closed my "main" window the one that is always restoring when I open firefox and it also said "you're about to close 20 tabs". Once again, sometimes this happens, sometimes it doesn't, but it always knows to restore it, so to me it's normal. I put my pc to sleep and I the next morning I turn on the pc and it opens a blank homepage. I think nothing of it, so I go to try and restore it through the history and that doesn't work. I go online to look how to restore it and it says everything about backup on the profiles folder. I go there and it isn't showing the files that I had, just the ones that I used this morning. I try to change the firefox profile to see if that window is in another one it isn't. I had hopes that it wasn't erased because that morning when I opened a window and I had more than 1 tab it said to me "would you like to close 4 tabs" and that always happens when there is more than one window open. So in the end I abandoned to recover the tabs I just could do it from the history. My WHOLE history that I collected for the past 6 years is gone and all my cookies. I have Firefox Sync and it shows my history on my phone, but when I go to sync it, it still doesn't show. I need help with at least recovering all my history and cookies; Bonus points if you can try to recover my lost window. Thank you!

I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?

My old laptop computer completely died. I installed Firefox on my new computer. However, after signing back into Firefox, my stored passwords and tabs were not available. How do I find/recover saved login passwords and tabs? I am a long-time Firefox user and had a lot of stored information that I assumed would follow my account.

Thank You,
