Firefox Support Forum

Seems like when I tried logging in to my old account with a password reset, I somehow created a second account with the same email.

All my bookmarks and extension set ups seem to be gone.

Never had this issue, and have been using the same firefox account for like 5 years.

Hello. Last night i had to reinstall windows and i lost everything. but in firefox i have loged in and synced. its also synced with my safari browser on my phone. is it possible in any way to get my bookmarks and passwords back? because everything is gone and the profile folder only shows dates after i installed firefox again!

Best Regards Kaveh

Howdy, I just need to sync Firefox on my iMac and on my MacBook Pro. But this is surprisingly difficult to do. [[this page|https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer]] says to "click the 'Sign In' button next to 'Sync and save data'". It shows a handy little screenshot of a Sign In button, but I cannot see said button or the Sync and save data button even though I'm signed in to Firefox. This page gives me a handy QR code to sync Firefox on my mobile device, but I want to sync Firefox on my laptop. This page [[about:preferences#searchResults]] ] says "Sorry! There are no results in Settings for 'sync'". (Why ever not?)

It seems it should be very easy to sync Firefox between two computers; indeed it should be blindingly obvious, but it's not. What am I missing here? Thanks in advance for your help.

Very similar to posts in previous years that are archived and largely unanswered or not up-to-date.

I opened up my a Firefox session to find out I was logged out of sync and when I logged back in all my passwords where erased.

This has been stable for the last 10 months and Firefox has provided a reliable password archive with nice syncing features. However, this is a deal breaker, since I cannot loose the login credentials randomly.

No updates. No conscious logging out. No disregarding warnings etc.

Anyway to revert or retrieve?

hello

Thank You

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.

Hi,

I have read through some of the past similar issues with passwords not syncing across devices and the only official answer I seem to find from the Firefox team is to "manually or force sync"...

However that does not work. I have just saved a new login on my mobile, I have manually synced or "sync now" on both my mobile and desktop, restarted both devices and still...this login does NOT appear on my Desktop.

So please help! For all I know there could be other logins saved on my mobile that don't appear on my desktop and vice versa.

I do not want to uninstall Firefox.

Kind Regards, Alex van der Merwe

My laptop crashed last night

Labelled as "Firefox Sync" as it may be involved, as the only preserved data is seemingly what comes through firefox sync.

Hi all, My C drive filled itself with 50GB of Crusader Kings 3 crash logs.

While the drive was (unknowingly) full, I opened firefox. Firefox was...wonky...and instantly I could tell something was wrong, as my speeddial homepage was missing all the sites. My best guess is that, in the worst timing ever, firefox sync chose this time to sync. I immediately cleared space on the drive, and restarted firefox. No extension data recovered. I restarted the PC. No extension data recovered.

I began following Firefox troubleshooting steps, such as checking about:profile. Other profiles are present, but each lacks any extensions or extension data. I widened my search with Everything, to search everywhere for any waylaid installs or profiles that may hold backups. Specifically, prefs.js, extensions.json, firefox.exe (incase I was somehow running a non-default install location) or any sign of other installations. I did find some hits, but none had extensions installed.

Perhaps useful, my FF profile weave folder is populated with many CORRUPT files, and the 'failed' folder lists addons, bookmarks, clients, extension-storage and prefs from it's most recent sync. Perhaps this is the result of trying to write to a full disk?

This is mostly an exercise of curiosity now, as the developer of Group Speed Dial (Juraj Mäsiar) helped me recover from their own backup system seperate from the Mozilla Preferences. I have an easy way to see if any backup file has the correct data, as I have many settings that are instantly visible.

Useful info: Antivirus - None added (Windows Defender) FF Version - 111.0.1 (64-bit) Profile - default-release

(Moz Helpers, the remainder of this post is irrelevant, and purely to help future travellers) If a weary traveller comes across this post in the future, I gift you my knowledge from the year 2023 of Group Speed Dial. At this time, the way you access the backups on your system is to navigate to the Group Speed Dial homepage. If you are on the default homepage, you should find the option to set it as New Tab or Homepage in Firefox settings. Next, as you face the oblivion of an empty dialler page, click the Burger Menu (top-right for me) for the extension. NOT the firefox burger menu, the one as if you were clicking a menu in a website. For me, the Fourth option is History/Backups. This is a new-ish feature from the developer, so don't be surprised if it move around...be they seem very proud of it, so I imagine it lurks somewhere!

If you just want to recover your extension list, at this time you can find a complete list of everything by examining extensions.js, extension-settings.js and extension-preferences.js. There is a tool online for helping parse into a human readable table, but I would not rely on it, and instead look into a generic JSON formatter to make the data human readable. The site is jeffersonscher.com, which has a extension file reader here https://www.jeffersonscher.com/ffu/extensionsjson.html

Have a nice day all!

Recently I activated 2FA on Firefox. I scanned the barcode by Google authenticator, to make it my code generator.

I'm now trying to enter Firefox on my laptop. After typing my password, when I try to enter one of the generated Google Authenticator codes, I constantly get a response "Invalid code".

I had to use one of the backup codes (out of the 8), and managed to enter my account on the laptop, but none of the logins and passwords were found there (it's empty).

My first question is why does Firefox reject the codes received from Google Authenticator (do I have to cancel my 2FA and define it once again? but I did everything by the book, with GA, and it seemed fine the other day).

My second question: I finally managed to enter my account with one of the eight backup code. Why are there no passwords etc? Aren't they automatically drawn from my usual (existing) account?

The laptop runs Win 10. I installed the 2FA on my main computer, which runs Win 11.

Thank you very much in advance, Eldad

Hi everybody this will be a long question, and I would be really grateful for any kind of help anyone could give me, this is my case:

I use `firefox-sync` to manage all my logins information and firefox-sync's password is the unique password I save manually.

Currently I has problems with my O.S and I decided reinstall it. But also I have 2FA enable for mostly of my accounts, and firefox-sync is not the exception, and firefox-sync's 2FA is based on my gmail, so when I tried get logged on firefox-sync, firefox asks me for my verification code, but my verification code is in my gmail, and my gmail's password is in firefox-sync.

So I lost access to all my accounts, I lose my gmail, github, gitlab, stackoverflow, discord, etc etc... :'(

From the gmail side, I tried all that gmail let me try but unsuccessfully.

So, the only possibility that I see, is recover the information of the formatted partition and rebuild the previous state of Firefox. I mean:

Reading about firefox loggins, and taking a look to firefox's workdir (`$HOME/.mozilla`), I see firefox saves login's info in a json file located in `$HOME/.mozilla/$profile$/logins.json`.

So the basic idea is with a data recovery tool, try recover `.mozilla`s directory and replace it over the current environment so when I start firefox can get access to my login's info. But I'm not sure how much it is possible to recover the whole directory, and if is not posible, my question is:

What files next to `logins.json` should be my recovery targets to replace inside the `.mozilla` folder in order to reconstruct my accounts login information?

My gateway had to reboot for tv issue. Everything came back as normal except for Firefox. It shows a blank page with only a search bar that does not function. Other browsers and programs work. Should I uninstall and re-install Firefox? This is the first time this has happened as I have had this browser for many years.

A recently added computer's Firefox is not available on the "Send Tab To Device" list.

Both computers are logged into my Firefox account and Firefox is syncing. The new computer populated with my extensions and other synced data. The new computer shows the old computer in it's Send Tab list, but the old computer does not have the new computer's Firefox name in the Send Tab list.

On both computers, I can go to the menu / Manage Account and see the list "Connected Services - Everything you are using and signed into." On both computers, I can see the other computer's Firefox name in the list, and it reports "synced a few seconds ago".

But when I use the context menu and try to send a tab under "Send Tab To Device" the new computer is not on the list.

This article does not discuss this situation. For the case of "I don’t see my device listed" it just says "Sign In", but that has already been completed and is working on both systems.

Hello! Since the most recent firefox update, my settings and extensions have been inaccessible to me due to my firefox account profile being "old." It has been working perfectly until this update. If I try to change my profile to my old one, it forces me to create a new one which does not include my saved addons and settings. I am able to usually manually move my bookmarks to the new profile via the files stored locally. I really need access to the settings and extensions, so it would be great if someone can help me to recover them. I tried to troubleshoot by finding my extensions local folder from my old profile, and I copied it to a new profile, but it didn't work. I am also wondering, if I do copy the extensions successfully, how can I also copy the settings preferences? Any solution is appreciated, thank you!

I tried this: https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update And I tried this https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_what-information-is-stored-in-my-profile

I can prove that I'm using the same e-mail address but with different domain thus making the last statement from [[an article here|https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication]] invalid.

Any idea how I can contact Mozilla to restore access or delete my account to recreate it again? Cannot find an e-mail address to create a ticket :( I don't want to use custom e-mail domain for Firefox account.

Thanks!

Good morning!

Since v112.0.2 my Firefox logged itself out of Sync and will not allow me log back in. When I click the "Sync and Save Data" in the pulldown menu, the page spinner just spins and spins. The login page never loads.

Oddly, I couldn't even login to my Mozilla account here to post this. I had to use "Ungoogled" Chromium to load the page. I've never had any Sync issues with FF, that I can remember. This just "appeared" with v112.0.2 and continues with v113.0.

I did try to access the Sync login page while in Safe (Troubleshooting) Mode... no difference, though; same spinning spinner.

I'm running Slackware Linux on a desktop computer. No other changes have been made on this system other than upgrading from FF v112.0.1. to v112.0.2. This is when the Sync issue started.

Any ideas? Any assitance would be very much appreciated. I could just go to Chromium full-time, but I would not want to do that. I've been a Mozilla browser user for 23 years. The Chromium is only on my system as a backup browser, along with SeaMonkey. Yeah... I have a Seamonkey. :)

Anyway, thanks in advance for any help/ideas to allow me to troubleshoot/resolve this.

Regards,

~Eric

I have stored some password with my account. Recently from past couple of days all passwords got cleared and not no passwords are shown. Could you please let me know what needs to be done.

Greetings, I have an iMac running OS Monterey 12.2.1. I use Firefox as my browser and it is 'up to date'.

My homepage is the Sydney Morning Herald, and I am a subscriber of many years. When I open the browser is shows the Home Page of the SMH, and shows my name as being 'logged on'. BUT, when I click on any story within that page to read in depth, it goes to that story, but requires me to 'log in' the password a second time.

When contacting Apple Support, they requested I try both Safari and Chrome to see if the same problem exists there. And, it doesn't. I can log on to the SMH site and then click on any story and read it without needing to log in a second time.

I am 84 years of age and find this rather frustrating... particularly as I do not have the cyber skills of a younger person. I am used to Firefox and prefer it as my chosen browser.

I hope you can advise me how to rectify this vexing problem.

Thanks, Frank Arnold I

Hi there, I'm hoping someone can help with this. I recently signed into a shared computer with my personal Firefox account, and it automatically imported all my history, my browser extensions, and bookmarks, including personal/secure information that I wouldn't want on a shared computer. I tried signing out and deleting the sites and login information, even going so far as to completely delete all of my browsing history and cookies and signing in with another account, but all the supposedly deleted history and logins and extensions were then transferred to this second account. I have deleted all my data, even uninstalled and reinstalled Firefox, and all the data from my personal account keeps haunting me as suggestions when I type in the task bar or suggested usernames when I log in to websites. How can I actually delete this information so it's not on a shared computer? Thank you!
