I have all my info in Mozilla sites, passwords... try to back up my new phone and WHAT.., back up the phone and erase all the info I have on mu computer!!!

That is crazy!

Firefox has exceeded all previous mess-ups by upgrading itself today (apparently sometime when my battery went flat and was then left recharging), and this happened despite my account being set for 'upgrades to be only installed manually'. Now every bookmark, all passwords and all the settings of my Home Page have been erased. I have no 'restore point' to resort to as supposedly all this info is synced to the cloud. But I can find no method to retrieve any of these files let alone one to restore them. This is a nightmare. Please help.

My old laptop crashed and I don't know how to access my old bookmarks and passwords.

Trying to go through SYNC did NOT help ... still nothing.

I need someone to help me figure this out.

I have reset/reinstalled Windows on this PC many times over roughly the past decade. Every previous time, I would reinstall Firefox, sign back into my Mozilla/Firefox account, enable Sync, and my data would come back: years of bookmarks, saved passwords, payment information, and other Firefox data.

I reset my PC again recently and did the exact same thing, except this time everything is missing.

Firefox Sync itself appears to be working normally. I am signed in, Sync is enabled, the appropriate categories are selected, and I can see that Firefox is syncing. The problem is that there seems to be nothing from my old Firefox data to sync back down.

I am also fairly confident that this is the same Mozilla account I have always used. This is the only email address I tested that behaved like an existing account with an existing password. Other email addresses I tried appeared to be treated as new accounts and asked me to create a password.

So I am not really looking for basic instructions on enabling Sync, manually syncing, checking the last sync time, or selecting which data types are synced. I have already gone through that.

What I am trying to understand is how an account that has successfully restored this same Firefox data after numerous previous Windows reinstalls can suddenly have none of that historical data available.

Specifically:

• Can previously synced Firefox data disappear from Mozilla's servers even though I did not intentionally delete it or disable Sync?

• Could reinstalling Firefox and signing into a newly reset/empty Firefox installation somehow cause the empty local profile to replace or wipe the previously synced server data?

• Are there circumstances where Firefox Sync effectively starts over with an empty dataset while continuing to use the same Mozilla account?

• Is there any server-side recovery, previous Sync state, historical copy, encrypted backup, or other mechanism Mozilla support can access when the current Sync dataset appears to be empty?

• Is there anything left to investigate on the old Windows installation/reset itself, such as a previous Firefox profile, Windows.old, recovery data, or another local copy, even if Firefox Sync no longer has the information?

• Is there any way to conclusively determine whether this account previously contained the missing bookmarks/passwords, rather than simply confirming that I am currently signed into the account?

The important distinction is that Sync is not currently “broken.” It appears to be syncing normally. The problem is that years of data that Firefox Sync had repeatedly restored for me in the past now appear to be completely absent.

I am trying to determine whether the old dataset may still exist somewhere, whether something could have caused the Sync dataset itself to be reset or replaced, or whether there is any remaining recovery path for the previous Firefox profile/data.

Hello,

after a rollback of my home system I looged into my Mozilla account to find out nothing synced over from the previous version that was installed on the same machine.

How can I recover everything (priority on passwords)

Best, Sebastian

Suddenly one day I noticed that all my website passwords for the Android app disappeared. The passwords were strangengly odd themselves because some were very old, others were recent and many were incorrect when I would try to use them and it seemed to be very random and not how they were originally saved. Anyways, they all disappeared one day and I don't know why or how. Apparently I had got signed out of my account for Firefox which I didn't even realize that I was signed into an account through the browser. I don't use just one same browser for the web I tend to use a bunch of different browsers since they all are disappointing. I'm just wondering why they all got deleted and why couldn't I sync the ones from my desktop to my Android. Thanks for the help.

Syncing is still something I don't understand I will tell you up front my smartphone is smarter than me I'm not techy somehow I watched Microsoft and Google interface with Yahoo and now I got each addresses answering each other's it's a mess on my end for the first time joining this I feel a fresh start for the first time I feel like I might be safe I'm not social media I don't post I don't post I don't copy I try to keep things simple so I don't understand a lot of things but I'm retired Marine sometimes my mind gets very reactionary bringing my stuff over mean something I'm going to have to accept that I don't like I don't even use Wi-Fi everything is hardwired ethernet that's the best I can describe my concerns thank you for your time

Hello, I have formatted my laptop and downloaded firfox, but I'm not able to restore my old bookmarks and passwords after I signed in to my account and sync. Could you help me with this and thank you.

I'm the only User of my Firefox browser and I noticed Firefox stopped filling out logins automatically when browsing on the internet. I was unable to access my logins in the preference menu under "manage saved passwords" as the list was empty. At first I didn't understand why. It seems that I hadn't created a "Profile" and was still using Firefox with my main account and as such was unable to access any previously synced data of that nature (under the updated Firefox configuration) I have now created a Profile but I don't know how to sync with my main account's login data list... I have read that I can locate a Profile folder to load previous data, but I'd rather find the main account folder if that's even possible, because the Profile folder hasn't synced any logins if I understand correctly.

Cheers for even reading this far ;)

Hi,

Over the weekend we had a break-in in our apartment and the laptop i use for work was stolen. I used Mozilla has my primary browser and had all the tabs and password i use on a regular basis saved there. As such I panicked a little and removed that PC from the synced units on my account. Now it seems I have no way to regain that information.

Is there anything I can do?

Thanks in advance, and best wishes

Help me to get back my data.

Hello, Today I performed a factory reset on my laptop (Windows 11). Before i did that, I checked if my Firefox account has synced all it's data, bookmarks, history etc. was checked and I pressed "sync" button. Then performed all of the actions connected with factory reset of a windows including partition removal. After that installed Firefox, logged in, but had to reset my password because it wasn't saved within my Bitwarden. Then synced and it turned out, that there is no saved bookmarks on my account. Is there a way to return my bookmarks?

Best regards, Karol Picher

Currently on Linux, but the problem is probably not OS-specific (although any work-around may be).

What I look for:

I want one setup for work, one for union, and one for personal use. If my work setup would be compromised, union bookmarks, search history etc is not compromised at the same time. Also, my work setup is not cluttered with private bookmarks and addons. Obviously, it'd be nice if those setups could be handled as separate start menue icons, so that I don't need to switch using a couple of clics, but just start the right setup directly. Needless to say nowadays, that these setups need to be syncable between devices. Ideally I as a person would have one Mozilla account that can store multiple profiles and protect each one with a seperate password, OR I as a person would have multiple Mozilla accounts that are made for easy switching.

What I've tried:

Multiple accounts, obviously; they sync between devices, which profiles really do not. The problem I run into is that I still need a separate profile for each account if I don't want to log in and out of them (which I don't want indeed, Alt-Tabbing during my leisure time is the only way for me to get things done for union and often for the office-part of work).

Finding the profile feature was hard enough but I adopted and have the about:profiles page bookmarked in all profiles. But whenever I start using a new computer, I need to set up new profiles. I tried saving them in a custom location on my nextcloud so that they can sync, but there is no straight forward way to import profiles. You need to create new ones and then move the contents of the old ones, instead of just pointing ff to an existing profile; that kind of kills the point of picking a custon location in the first place. All I ever do with a new profile is logging in to one of my already highly profiled accounts.

Along the way I realized that there is a now more GUI-way to create profiles, so I tried that. But when I tried choosing a custom location for them, I failed. Took me a while of restarting and googling to find out that Mozilla has managed to have two completely seperate features with the exact same name! That is, when you create a profile the modern way, it does not appear in about:profiles and vice versa.

Since I ditched the idea of custom location anyway, I setteled with the new way. But when I thought I'd make seperate startmenue links for them, because surely you can handle that with some kind of flag in the command, I could find only one option for profiles, and, as you can guess, it works with the old profiles.

It seems that one can start with a profile at a certain path, so maybe the old way with custom path could be something for me anyway, but when I used such a profile, I got a warning message that says that history and bookmark functions might not work properly and that some security program may cause this.

So, how is one actually supposed to use different accounts OR how is one supposed to sync different profiles between devices?

Hello,

I have a new laptop and I am trying to recover my old Firefox data. On my previous laptop, I had Firefox bookmarks, saved passwords, browsing history, and other browser data. None of this information has appeared on my new laptop.

I have also forgotten the password for my Mozilla account. I tried to recover the account, but my bookmarks and other data are still missing.

Could you please explain how I can safely restore my bookmarks and saved login information?

My old laptop is [still available / no longer available]. The new laptop uses [Windows/macOS/Linux].

Thank you for your help.

Okay, I do save a lot of bookmarks. But I'm not sure how they would ever add up to more than a gigabyte of user data. I already cleared my cache, and there's still 1.37 GB of "user data". The Firefox app doesn't seem to have a way to display a menu selection where I can get it reveal the contents of my "user data", or UD. Interestingly, my UD on my other devices is also gigabytes in size, across devices newer and older devices, and even desktop on Mac OS.

I am loath to delete my UD on my devices without knowing exactly what I'm erasing. And in the app, regarding the bookmark function itself, it seems that all bookmarks are stored locally on the device that they are created on. It's nice that with the sync function in the desktop app that all my bookmarks across all my devices can be ACCESSED using my desktop browser. But to SAVE, those non-local bookmarks would need to be manually opened in my desktop Firefox browser and then re-bookmarked to actually be backed up. Currently, as it stands, if I lose the device or clear the UD, I lose the bookmarks. I verified this situation using my desktop Firefox browser, which shows the root directory of bookmarks which are not locally stored in the desktop Firefox browser as "_other". And, interestingly, even with sync on across all my devices, I still can only see locally stored bookmarks on my cell phone devices; I can only see all synced bookmarks using my desktop Firefox browser.

So what I need to know is, does there exist a good way to quickly save bookmarks from, say, cell phone devices to a desktop version of Firefox, with hard drive space. And, I would also like to know how to access all the data in the UD part of the mobile device and desktop apps, so that I know what data the app is saving, and therefore, what I want to keep and what I want to delete.

I have a Firefox account I use as my default work browser. My organization's latest software updates forced me to re-install the latest version of Firefox. I specifically un-checked the box when installing that suggested clearing my settings and extensions, etc because I wanted to retain the way my profile was configured. When I logged back into my account, ALL of my settings, extensions, and YEARS of bookmarks I need to do my job have been completely wiped, and there seems to be nothing in my account that will allow me to recover them--the profile I've been using for year seems to have been completely reset, with all its history completely wiped.

Is there any possible way I can recover my bookmarks?? I did not create an external backup and realize that makes things harder, but I assumed my profile would retain its history as it was tied to an account I was always logged into.

Hi

I have been using Firefox mobile for many years. Recently I wanted to remove sone pinned websites on my home page. i was told the only way to achieve this was by using the desktop version as the mobile version did not support this action. i installed Firefox onto my laptop but on synchronisation it appears that the laptop has told the mobile that it is a new `setting` and not used the mobile as the `original`. I have now lost all of my bookmarks that i have collected over years on the mobile version. Can you suggest a way of restoring this and telling the laptop to use the mobile settings?

Regards

Paul McNeill

Hi, I'm pretty sure the email I am signed in with now is what was tied to all of my bookmarks in Firefox but I had to do an account recovery and I did not have my key. When I was able to sign back in and hit the sync button nothing updated.

I am really, really hoping I did not lose everything here... is there anyway I can recover my bookmarks/passwords?
