Hi, I created mozilla account and turned on synchronization to save my passwords, history, etc. After I done it, I formatted my pc. Now I've just downloaded mozilla and log in to my account to see that NONE of my data were saved... How is it even possible? I turned synchronization on and then selected which data I want to save. Will you be able to help my with that?

I sent another help request on this subject but that too seems to have gone AWOL so I am trying again.

My passwords are being randomly wiped from my PC yet again but this time, although they are still on my Google Pixel 7 phone, Sync is not working for passwords. Strangely however, tabs are being synced.

I have tried every suggestion that I have found but syncing is just not happening.

To re-cap:- Passwords are not being synced from phone to PC Tabs are being synced between phone and PC.

Any suggestions?

When I'm on my phone and signed into my Firefox I want to be able to send tabs to my desktop. I'll click the three dots on my Samsung 20fe, click share, and click send to device. My p.c. is listed and when i click on it, a box pop's up and says "tab sent. I don't know where it's going, but it's not making it to my desk top. I've tried logging out and logging back in. on both devises

The android UI was updated in recent Firefox updates and it is now impossible to enable sync from an Android phone due to this change.

According to Firefox during setup the proper steps are:

1. Open firefox on your mobile device. 2. Go to the menu and tap "Sign In" 3. Tap Ready to Scan and hold your phone over this code.

The new android UI does not have one universal menu. Instead it includes a list that lets me:

• Bookmark a Page
• Find in Page
• Turn on Desktop Mode
• manage Extensions
• "More"

It also features:

• My Name for managing and backup/sync
• Settings

I'll enumerate the issues with this.

If I select More. This is different than the more settings options under "Settings". It allows me to:

• Translate the Page
• Add to Shortcuts
• Add to Home Screeen
• Save to Collection
• Open in App
• Save to PDF
• Print

All of these are irrelevant.

If I select my Account, the most obvious of these ambiguous choices. I can:

• Manage Account
• Sync Now
• Change the Device Name
• Sign Out
• Choose what to sync.

There is NO option here to scan a QR code. Manage Account leaves the app and opens a mozilla account webpage. None of these options work.

If I select "Settings" I receive a large list of useless options - none of which allow me to scan a QR code.

Since scanning the QR code is the ONLY way to enable syncing via the mobile app am I understanding correctly that Firefox has removed this feature and is mistakenly still advertising a deprecated feature inside their MacOS app which prevents me from actually ever signing in to my account.

If this is intended to still be a feature. How do I do it? The instructions are unclear and your UI does not help in any way to figure out how to navigate to the correct place where I might possibly be able to move forward in any manageable way.

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?

1.syncronising in firefox mobile app is awful if you delete some tab witg your linux firefox it wont syncronise with your phone anymore and wont let you to sync manualy(the sync button will freeze) and even do if you dont do anything sync button will freeze and wont sync with linux firefox. when this happen i have to uninstall my firefox and reinstalled it.

I recently switched to Linux on both my laptop and desktop computers, and I have started having an issue where after closing Firefox, the process does not end fully, leading to a Firefox crash notice after a minute or two.

This seems to only happen when I have sync turned on. It always says "syncing..." and never finishes, and logging out of my account or turning sync off fixes this problem. However, I'd really like to be able to use sync across my two systems.

My laptop is running Pop OS, and my desktop is running CachyOS. Making a new account fixed this error for a few days, and now it is happening again.

Here is my newest crash report: https://crash-stats.mozilla.org/report/index/9adbdc82-3cfa-49b7-8bad-e6e590260319

After the latest Firefox update (ref 4b7ede), my bookmarks and saved passwords are not syncing. Tried signing out and back in.

so I did a factory data reset of my s22 Plus last week and I just tried to send it a tab from my Mac to my phone which doesn't work but it works the other way. The device was still signed into my account I signed it out sign it back in from the phone and every time I try to scan the QR code to connect another device from the QR code scanner in the search bar of the Firefox browser it keeps saying that I need to use like another app because it thinks it thinks I'm using the phones camera I'm not quite sure where to go from here

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

I am signed in on all my devices. Yet nothing has synced since October 2025. So none of the books marks from my laptop display on my desktop in bookmark folder. The folders don't even match what is on my laptop. How do I fix and how do I prevent in the future?

Firefox 135 on Linux (Ubuntu) and latest Firefox on Android. All sync items are checked. Passwords sync, and bookmarks toolbar syncs, but not bookmarks in folders appear - they're just not there.

Because the bookmarks toolbar is synced it confirms that Bookmarks are checked under sync on both devices.
