Hello,

For some reason, when I try to sync all my stuff from my desktop Win 11 firefox/duckduckgo system, to my new Win 11 laptop, the only option I can get is to sync with a mobile device.

I had no trouble doing this some months ago with another laptop, but this time I cannot find how to do this after trying for over an hour . . . . . .

Has anything been changed that won't allow syncing with another 'big' device, please?

Hello Mozilla Support Team,

I am writing to request assistance with recovering my Firefox Sync data.

I recently reset my PC and after reinstalling Firefox and logging back into my Firefox account, my bookmarks and saved passwords are completely gone. I believe the sync may have overwritten the server-side data with an empty local profile after the reset.

Account email: [edited from public] @gmail.com Approximate date of data loss: 02 25 2026

I had been accumulating this data for approximately 1 years and it is very important to me. Could you please check if there is any backup of my sync data on your servers that could be restored?

Thank you for your help.

Firefox is disconnecting my account every time i restart the browser. I've made sure it's not set to clear data when restarting. I found a support forum post for mac where they weren't installing it and were running it from the dmg, but i'm using the firefox that was installed during cachy installation, which firefox gives /usr/bin/firefox, when runnign it from terminal (or anywhere) the command in btop is /usr/lib/firefox/firefox. its really frustrating because i lose my session data, have to log back in again, have to redownload all my extensions, ahve to reconfigure all my extensions every time the browser restarts

I'm on CachyOS on COSMIC de with a btrfs file system. I've tried uninstalling and reinstalling firefox. I've tried making a new profile. I really don't want to use a different browser, but this isn't functional.

what happened:

1: my pc is broken, then I got new system and hdd. 2: I download firefox and login. 3: Press Sync now and nothing happen.

ARE YOU KIDDING ME ?

What I want:

I want my bookmark back.

I used firefox soo many years.

PLS tell me I can take it back.

Hey, I am trying to synchronize my mobile tabs with my desktop app. Unfortunately, this is not working. I am using the latest version of Firefox and Windows 10. Any ideas how and if I can solve this problem? Thank you in advance.

I have changed operating systems from windows to linux mint. I made sure to sync my profile before uninstalling, but now the profile looks to be empty. there are no saved passwords or bookmarks. This worked when I changed between different windows devices last year, but this time it seems stuck. I will check on a windows device when able, but in the meantime, are there any other ways to troubleshoot this?

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Hi all, Starting at the weekend or end of last week I think, when I send tabs to another device when that device is switched off then when I open Firefox on the other device, the sent tabs are loaded in private browsing windows, not the main window with my saved tabs in. Sometimes all sent tabs arrive in one private browsing window, sometimes in one private browsing window for each tab. As I can't drag private tabs into the main window this is really annoying! How can I stop this happening please? Cheers :)

So I just switched OS on my desktop, and had to log into Firefox all over again for the first time in a bit, and it turns out that for some reason my saved passwords arent synchronising with my whats saved on my phone? In the past my experience have been that if I ask firefox to save my password on one device it remembers it on all my devices. Is this not the case? Is there something I need to do to manually synchronise?

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?

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?

After the latest Firefox update (ref 02fc63), my bookmarks and saved passwords are not syncing. Tried signing out and back in.

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

I use an iMac (2019) and MacBook (2015) but my tabs aren't syncing between the two.

I've refreshed the syncing a few times but the MacBook is still showing two lots of tabs for the iMac, and both of them are showing pages that are no longer open.

I'd really like to be able to move between the two so if anyone has any suggestions on how to get FireFox to sync, I'd be really grateful. :-)

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?

I just wanted create Account recovery key to keep my account more secure. So I did that + updated my password.

Now when I open the browser, it says account disconnected and that I need to create a new profile. I did that, but it started syncing from old chrome account with old extensions, bookmarks etc. Plus bookmarks from my phone.

I try to sign in and create new profile with the original profile settings that I want. But it keeps saying "This profile was previously synced to a different account". And now that I saved the bookmarks and made a third, fourth profile. Those don't work as it wants me to sign in. Only the 2nd profile that Firefox made me create which has the old extensions, bookmarks etc. It is missing a lot. So now I am just stuck in create profile loop. And cant use the one I want because I wanted more security? Do I need to uninstall and install again, would that help? I wish there was someone to talk to help me. I just want to use my original profile that I used earlier today to update the security settings.

I have a desktop and a laptop on firefox. I am selling my laptop so i cleared history and deleted all bookmark history.

To my horror, even though i remember i have signed out of mozilla account on the laptop firefox, on my desktop firefox all the bookmarks including bookmark folders are gone. Thankfully, i have a fairly recent backup of firefox userprofile file so i restored them.

However, to my horror once more time, I realize now firefox sync automatically deletes my bookmarks everytime it syncs so i have to turn it off.

How can i make firefox sync to treat my current bookmarks as the latest and stop deleting them?
