I-Firefox Community Forum

Hello,

Earlier today I reformatted my device but when I logged in to firefox I can only see my history is getting synced my bookmarks are empty, I've checked and bookmarks are check off and they should be synced. How do I get them to sync? It has worked fine in the past. Thanks.

so i was using my pc (and firefox) normally, when i then turned off the machine as usual.

when i turned my pc on again and opened firefox, everything was gone, i wasn't signed in and all my bookmarks and several home url's were not there, you don't need me to tell you that's not normal.

of course, i followed the most logical course of actions, i signed into my firefox account (from which i am sending this ticket), and expected all my data to magically sync, which it didn't, so i then tried to sync in manually, looking for any backup file on my pc (i couldn't find any, though i can't say i know what one looks like so...)

hopefully this can be fixed because i had auto-sync on and it would be a bummer to lose everything and slowly rebuild my browser ui from the ground up

thanks in advance, GR

Hello, I am transferring to a new device but my device is not syncing and just loading even when I tried to close and open Firefox. I've tried to also log this in via support but to no avail. Appreciate any help on this. Thank you!

I have switched from chrome to firefox on my windows 11 laptop. I want to do the same on my pc but after signing into the Mozilla account, the bookmarks do not come in. History, and other things seem to work fine. I tried manually synchronizing in the settings over and over again but nothing works.

I have no idea what to do other than going back to chrome where things just worked and I didn't have to spend hours looking at forums for solutions that do not work...

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?

Hi,

I changed my password in my Mozilla account and now I can no longer sync my firefox for android.

I scan the QR code and on my android screen proceeded normal and asking me to confirm but in my desktop I get an error.

"General application error Something went wrong. Try again later."

I also tried in safe mode with no luck.

What to do now?

Dear Firefox Support,

I recently installed a fresh copy of Windows 11 and then installed the latest version of the Firefox browser. However, when I try to sign in to my Firefox account, it does not sync any of my data. My bookmarks, passwords, browsing history, and other synced items are not appearing.

I have tried clicking the "Sync Now" button, but nothing happens. I would appreciate your assistance in resolving this issue so I can recover my data.

Thank you for your support.

Best regards,

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

15/12/2025 I need to sync my firefox data from my old windows 10 laptop to my new windows 11 laptop. Do I have to download the firefox app on to my new laptop before I can sync it, and will I need a new password if I have to download the app. Im using my old password on my old laptop to write this. On the new laptop, I tried to sign into firefox on the internet but, it said my password is wrong. I'm an oldie and have no idear what to do. Iwill be very grateful for any help. Many Thanks,

                                                                                           Janet.

Firefox won't sync anything since a while back, maybe since two months back, I am unable to force sync. Clearing cashe, uninstalling the app, relogging both phone and pc, neither of these syncs bookmarks across the devices. I am able to send tabs in-between the devices. Biggest issue is I can't save bookmarks on one device and expect them to be available on my other device Nokia 7.2

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

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.

Dear Support,

Since ages ago I've always logged into Firefox and turned on sync so whichever device I was on (or if I have formatted my PC) I would still have acces to my browser history, tabs etc. Today I've formatted my PC to switch from win 10 to win 11 and logged into firefox as usual, but after trying to Sync nothing happens. My tabs, my history, everything is empty for some reason and I cannot find my original device (the one from a few hours ago connected in win 10) in my connected devices list either.

Please help me, my whole life is in that sync :(

Best Regards, Peter

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.
