Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.

I'm attempting to set up Firefox in a newly installed OS and have logged into my Sync account. Many aspects seem to be loaded in, but the status via the Settings is stuck at "Syncing..." despite waiting several hours. Quitting Firefox results in a crash window popping up.

There are no files in the weave/logs directory. The weave/failed directory has multiple json files; most almost completely empty. addons.json has an ID, but that's pretty much it.

Deleting the .mozilla directory and starting over yielded no change in behavior.

Any help would be appreciated. Thank you.

Hello,

I recently reinstalled Windows on my computer and expected Firefox to sync and restore my saved passwords, as I had enabled Firefox Sync before reinstalling. However, after syncing my account, my passwords did not appear, and I am unable to access them.

I have already tried the following steps:

   Checked the sync status of my Firefox account.
   Ensured that I am signed into the correct Firefox account on my browser.
   Searched for any relevant troubleshooting steps but haven't been able to resolve the issue.

Could you please assist me in restoring my saved passwords or provide any guidance on how I can retrieve them?

Thank you for your help.

Best regards, Tameem

I was having some hard drive trouble so I formatted my pc. I did not think much of the browser favorites and tabs because they should have been synced.

This time, however, I seem to be unable to retrieve the data from my old computer, there is even a computer in my synced items (I'm hoping from the system before restoring, windows 11 on what used to be windows 10) but am unable to get anything from it, or see the history ect

I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

Historically, I remember when you open the `sync` sidebar and right click on the tab grouping (i.e. Firefox on iPad), it opened a context menu where you had the option to `open all synced tabs`. This seems to be missing from the latest version of Firefox (138), but wanted to check in to see if I'm missing something or if I should downgrade my version of Firefox to get that functionality again.

I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

Yesterday, I noticed after I closed and re-opened Firefox, my browsing session was completely gone - all my tabs and windows, my entire browsing history, website sign-in status, all completely gone. I've been troubleshooting since then.

I've noticed that the 'sessionstore-backups' folder in my profile folder is missing. When I open Firefox, this folder is created and Firefox writes some data to it, but Firefox seems to delete the folder as soon as I quit Firefox. Firefox should not be doing this. My Firefox is configured to open previous windows and tabs, and is NOT configured to wipe any browsing data of any kind when it closes.

As a sanity check, I spun up a Windows Sandbox (briefly, it's a clean, isolated Windows environment) and installed Firefox there. I also enabled the option 'Open previous windows and tabs'. Firefox behaves normally - it re-opens the tabs/windows I had open when I quit Firefox. Great, that's what I expect. The trouble starts as soon as I sign in to sync. After signing in to sync, and letting the initial sync process complete, I open a couple of windows and tabs, then quit Firefox. Firefox begins nuking my browsing session again - the 'sessionstore-backups' folder is erased, and next time I start Firefox, all my windows and tabs are missing, and my browsing history is missing.

So, at this point, I'm assuming something in my synced data has become corrupt. I haven't installed any new extensions lately. I haven't changed any of Firefox's settings that would cause this to happen. The only thing I have done differently lately was enable Firefox Sync in LibreWolf and sign in to sync there. It seems like this session-nuking trouble started after I signed in to sync in LibreWolf. I assumed, since LibreWolf is a fork of Firefox, and because there were no warnings or indications the feature was incomplete/unstable/experimental/etc., that it would just work, that it wouldn't cause any issues. But it seems like it has caused issues. I checked LibreWolf's issues tracker for anything related to 'sync', but I didn't see anything noteworthy.

I've been using Firefox and Sync for numerous years without issue. This session-nuking thing started yesterday.

I use Firefox in a few places, and based on what I saw happen in my Windows Sandbox, this session-nuking issue is going to happen in every Firefox I'm signed in to as soon as it has a chance to sync. Obviously, I do not want this to happen.

What can I do to determine what the issue is? What can I do to check if something in my synced data has become corrupted? What can I do to reverse it? I'm not opposed to completely wiping/resetting my synced data, but I'd rather not if I don't have to. The only thing I would lose sleep over is my bookmarks, but I know I can export them. Are there any debug logs I can enable/look at? Anything I should look for in Event Viewer?

Thanks.

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

My work is trying to fire me because they say Firefox was mirroring my activity at home and vice versa. I.E If I opened a tab at home it when then open a tab and attempt to connect to same website on my work computer in the office.

I’m fairly certain it doesn’t cause that would be wildly unnecessary for what sync tabs is trying to accomplish but I used wireshark to watch for outgoing connections on my home desktop and opened a tab on my phone and my personal laptop and wireshark never detected outgoing connections to the tabs on other devices

I installed (as always) the new Windows 10, downloaded from the office. firefox website. I log in to my login, synchronization takes place (firefox says so) but MY data is NOT!!! no synchronization, no loading of passwords, addresses, extensions!!!

I have a question regarding syncing. Is there a way to remotely remove all synced information from Firefox on a particular PC without actually accessing it? For example, if I sync my home PC Firefox with my laptop or my work PC. Then, one day, for some reason I no longer have access to my work PC, and all of my sensitive information is there. Or if I lose my laptop, or if it is stolen... Is it possible to remove all sensitive information from a remote synced PC? Alternatively, is there a way to remove all synced information every time I close the browser? This way I can remove a particular PC in my Firefox account and once the browser is restarted at the remote location, the data will no longer be pulled and synced. Can this be done? Thanks in advance!

Hello! I have a serious problem. I lost access to my data because I changed my password, so my data is no longer synchronized. I reinstalled my Windows, and I forgot the old password I had on that Windows. As I reinstalled, I decided to change the password because I didn't remember it, but after that I found out that synchronization doesn't work. Please help me, I had very important bookmarks that were there. Thanks in advance!

My computer died today due to water damage, which means I can't turn it back on again. I got a new computer, I've looked all over the Firefox support websites, and can't find a solution as to how to get all of my Firefox data onto this new computer. I tried the profile page, but it looks like a profile for my old computer's Firefox never even existed. I have no idea where to find any of my old data.

Every time i setup a new Firefox install and login with my Mozilla account: my homepage configurations reset. I lose all my pinned shortcuts and the related layout settings.

And I doing something wrong? I install, make a few basic config changes in Firefox to match what I want, then I sign in, and poof: i lose my homepage on ALL my active sign-ins.
