Firefox Support Forum

Dear Team, I am facing issue which is firefox sync issue even i have login my firefox account successfully but the data did not sync yet? Email: [edited] @gmail.com

Hello Today, after installing the new Windows, I also installed the Firefox browser. But after I logged into my regular Firefox account, none of my previous account information, including plugins, bookmarks, and passwords, synced. I used this account for several years and all my information was stored in it. please guide me.

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

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

This morning when I turned on my PC, Mozilla didn't restore my previous session across 4 different browser windows. Normally, it restores my session (and the 4 windows) automatically. But this time, it didn't. I opened Mozilla, but the "restore previous session" option didn't generate the previously open windows.

I've lost hundreds of tabs that I had open... is there any way to restore my previous session?

Thanks in advance!

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!

Firefox can sync anything except logins and passwords between different devices. I have selected "Logins and passwords" at "settings-Sync-You are syncing these items across all your connected devices", but it still dosen't work.

Sir, I re-flashed windows on my laptop about 14 days ago. When I install Firefox the mail password in sync shows wrong. Then when I add a new password to the Forgot Password again, I lose my previous bookmarks. Where I had many important credentials. Please help me by returning them. Thank You.

hello

Thank You

I want to do a refresh of my firefox profile for it was overwriten with another profile or it was combined with another profile. So how can I start from scratch without my current profile been overwritten by what is stored on the cloud.

Firefox was crashing my phone (android) all of the time (not the problem) so I uninstalled and reinstalled the app, and was assured this would not be a problem as mozilla store all logins book marks etc, on their servers and a simple sync would restore all of that. It did not. I've since discovered that in actual fact reseting your password is pretty much the same as deleting your ENTIRE account, including all of my saved logins, bookmarks etc. This is unbelievable to me. I literally cannot believe that a tech organisation as large as mozilla has no way of retrieving, or allowing me to retrieve my own data because i changed my password. That's not my account. That's an entirely new account... or is it? Please help.

When I refresh my inbox, the items appear and then immediately disappear. All of my folders are still visible and when I open a folder, I can see all of the items and they do not disappear. I am running MS Outlook on a Macbook Pro with macOS Ventura 13.3.

My inbox is visible on both my iPhone and iPad. It is only on the MacBook that the inbox disappears.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS and not iOS.

My laptop was stolen. In my new laptop I try to open all my sync tabs at once, but I can't. I signed in, I see all the sync tabs under the "sign out", but how can I open them all at once? I read that I should right click the devise name to do that, but I can't right click it.

Hello. Have a problem with syncing passwords across two (for now) PC's. On my work computer I logged in to my Firefox account and imported some passwords form a file. After that, came home, logged in on home computer and see, that passwords are not synced from those, that I imported on work PC. What.s the problem?

The logins that I put manually synchronize with the account between the devices, however, the passwords that i imported from chrome through the .csv file do not sync.
